SEO Basics(17)

What is SEO and where should I start?
SEO (Search Engine Optimization) is the practice of helping search engines properly understand and rank your website. Start with (1) optimizing title tags and meta descriptions, (2) organizing heading structure (h1-h3), and (3) registering with Google Search Console. Rather than complex technical work, focus first on clearly communicating your page content to search engines.Check your SEO score for free
How does Google determine search rankings?
Google uses over 200 ranking factors. The main ones are (1) content relevance and quality, (2) quality and quantity of backlinks, (3) user experience (page speed, mobile-friendliness), and (4) E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness). No single factor guarantees top rankings — you need to improve multiple factors comprehensively.
How long does SEO take to show results?
Generally 3-6 months. Google needs time to crawl, index, and stabilize its evaluation of pages. Technical fixes like title tag changes may reflect within 1-2 weeks, but building overall domain trust and content authority takes months. Be wary of anyone promising immediate #1 rankings.
What are backlinks and why are they important?
Backlinks are links from other websites to yours. Google treats these as 'votes of confidence.' Quality matters more than quantity — links from relevant, trusted sites are most effective. Unnatural links (purchased links, mass link exchanges) can trigger penalties. The fundamental approach is creating content that naturally attracts links.
What is E-E-A-T?
E-E-A-T stands for Experience, Expertise, Authoritativeness, and Trustworthiness — Google's content quality evaluation criteria. It's especially important for YMYL (Your Money, Your Life) topics like health and finance. Improve it by clearly stating author credentials, publishing expert content, earning backlinks from trusted sites, and providing accurate information.
What is a good SEO score?
Generally, an SEO score of 80+ indicates solid SEO fundamentals. Scores of 60-79 suggest room for improvement, while below 59 requires urgent attention. The score is a guideline — what matters is identifying which specific items are lacking and prioritizing high-impact improvements. Our tool diagnoses 45 items across 4 categories with auto-generated improvement code.Check your SEO score for free
What is domain authority / domain power?
Domain authority is a concept describing a domain's overall trust and authority in search engines. Moz (Domain Authority) and Ahrefs (Domain Rating) quantify it with proprietary metrics, but it is not an official Google ranking factor. It reflects backlink quality/quantity, site age, and content depth. Domain power itself does not directly determine rankings — it is a reference metric calculated by individual SEO tools.Check your domain power
What is indexing?
Indexing is Google's process of storing crawled web page information in its database. A page must be indexed before it can appear in search results. Check indexing status via Google Search Console's URL Inspection tool, where you can also request indexing for individual pages. After publishing new pages, update your sitemap and request indexing through Search Console.
What happens if you don't maintain your website?
Neglected websites face multiple risks: (1) Ranking decline — Google considers freshness as a ranking factor, and sites without updates tend to lose positions over time. (2) Security vulnerabilities — outdated CMS and plugins create attack vectors for hacking and malware. (3) Outdated information — wrong prices, hours, or contact details erode user trust. (4) Technical decay — expired SSL certificates, broken links, and layout issues accumulate. At minimum, perform monthly security updates and quarterly content reviews.Check your site health for free
What does SEO stand for?
SEO stands for 'Search Engine Optimization' — the practice of improving a website's visibility in search engine results (Google, Bing, etc.). It encompasses all strategies and techniques used to rank higher in organic (non-paid) search results. The term covers both content optimization (keywords, quality) and technical optimization (site speed, mobile-friendliness, structured data).
What is technical SEO?
Technical SEO focuses on optimizing a website's infrastructure to improve crawlability (how easily search engines can navigate your site) and indexability (how easily pages get added to search results). Key areas include page speed, mobile responsiveness, HTTPS, XML sitemaps, robots.txt, structured data, and Core Web Vitals. It complements content SEO by ensuring the site's foundation is solid for search engines to process.Measure Core Web Vitals
What is local SEO?
Local SEO optimizes your online presence for location-based searches ('coffee shop near me', 'dentist in Shibuya'). Google Business Profile optimization is the most critical element — accurate address, hours, photos, and review responses. Also important: location-targeted content, consistent NAP (Name, Address, Phone) across directories, and backlinks from local media. Essential for any business with a physical location or defined service area.Use the local SEO tool
What is content SEO and how do I do it?
Content SEO is the practice of creating and improving content that matches user search intent to rank higher. While technical SEO builds the foundation, content SEO wins with substance. The process: (1) research keywords to understand demand, (2) analyze search intent to identify what users need, (3) study competing top pages to find content gaps, (4) create content with original experience, data, and insights, (5) measure results in Search Console and improve through rewrites. This cycle of publish-measure-improve is the core of content SEO.Use the keyword research tool
What is the click-through rate (CTR) for each search position?
According to Advanced Web Ranking's 2024 data, Google position #1 gets ~39.8% CTR, #2 gets 18.7%, #3 gets 10.2%. It drops sharply from position #4, reaching ~1.6% at position #10. Positions 1-2 alone capture roughly 60% of all clicks. However, queries showing rich results or AI Overview tend to push organic CTRs lower. The most effective way to improve CTR is optimizing title tags and meta descriptions.
Why did my search rankings suddenly drop?
Five main causes: (1) Google algorithm update — core updates frequently cause ranking shifts. (2) Manual action (penalty) — check 'Manual Actions' in Search Console. (3) Technical issues — robots.txt misconfiguration, accidental noindex, server errors. (4) Lost backlinks — a major linking site removed your links. (5) Stronger competitors — rivals published better content. Start by checking Search Console for errors and manual actions to identify the cause before taking action.Check your SEO score for free
How do I check my search rankings?
Three methods: (1) Google Search Console — the Search Performance report shows average position for each keyword, free and most accurate. (2) SEO diagnostic tools — our tool instantly diagnoses SEO score and improvement areas from just a URL. (3) Incognito mode search — shows non-personalized results, though location and device differences remain. Search Console is the most reliable source for accurate ranking data.Run a free SEO diagnosis
Why aren't my search rankings improving?
Common causes: (1) Search intent mismatch — your content doesn't match what users are looking for. (2) Overpowered competitors — established domains with strong backlinks targeting the same keywords. (3) Technical issues — slow pages, poor mobile experience, indexing problems. (4) No differentiation — rewriting what competitors already cover without adding unique value. (5) No backlinks — even great content struggles to rank with zero backlinks. Start by improving pages that get impressions but few clicks in Search Console.

Basic SEO (Tags & Headings)(8)

What is the optimal title tag length?
The recommended title tag length is 50-60 characters for English. Google displays approximately 50-60 characters in search results, truncating longer titles with '...'. Place important keywords at the beginning and brand names at the end. On mobile, even fewer characters are shown, so include the core message within the first 40 characters.Read the title tag guide
What is the optimal meta description length?
The recommended meta description length is 150-160 characters for English. Google may display up to about 160 characters. However, Google often rewrites snippets automatically, so include your search intent answer and CTA within the first 120 characters. While not a direct ranking factor, it significantly impacts CTR.Read the meta description guide
How should heading tags (h1-h6) be used?
Heading tags indicate document hierarchy. Use one h1 per page for the main title. h2 marks major sections, h3 marks subsections within h2. While skipping levels (h1→h3) isn't an HTML error, maintaining logical hierarchy (h1→h2→h3) helps search engines better understand content structure.Read the heading tags guide
What is a canonical tag?
A canonical tag (rel="canonical") tells Google which URL is the 'official' version when the same content exists at multiple URLs. For example, if a parameterized URL (?sort=price) has the same content as the base URL, canonical specifies the preferred URL to avoid duplicate content issues. Self-referencing canonicals are recommended for every page.Read the canonical tag guide
Is alt text required for all images?
Alt text is required for meaningful content images — photos, charts, and infographics should have descriptive alt text. Decorative images should use alt="" (empty alt) for accessibility. Alt text is also a ranking factor for image search, directly impacting SEO.Read the image alt guide
What are OGP tags?
OGP (Open Graph Protocol) tags control how your page appears when shared on social media — title, description, and image. The four basics are og:title, og:description, og:image, and og:url. Without OGP, social platforms auto-extract information, which may not represent your page well. While not a direct ranking factor, OGP affects social traffic acquisition.Read the OGP tags guide
How do I set up hreflang tags?
Hreflang tags tell Google which URL corresponds to each language/region version of your content. Use <link rel="alternate" hreflang="en" href="URL"> format, with mutual references between all language versions. Include x-default for the fallback URL. Proper setup ensures the right language appears for each user and prevents duplicate content issues across language versions.
What are the SEO benefits of breadcrumbs?
Breadcrumbs serve three SEO purposes: (1) Site structure comprehension — helps Google understand page relationships. (2) Rich results — implementing BreadcrumbList structured data can display breadcrumbs in search results. (3) Internal linking — provides natural links to parent pages, distributing link equity throughout the hierarchy.

Keywords & Content(9)

How do I choose the right keywords?
Keyword selection follows three steps: (1) brainstorm keywords related to your service, (2) expand candidates using Google Suggest and related searches, (3) prioritize by search volume and competition. Start with low-competition long-tail keywords (3+ words), then gradually target broader keywords as your authority grows.Use the keyword research tool
What are long-tail keywords?
Long-tail keywords are specific search queries with 3+ words. For example, 'SEO' is a head keyword while 'free SEO score checker tool' is long-tail. They have lower search volume but higher conversion rates due to clear search intent, and less competition makes them easier to rank for. New sites should start with long-tail keywords.
How do I check search volume?
Three main methods: (1) Google Keyword Planner (requires Google Ads account, free version shows ranges), (2) Google Suggest + keyword research tools (our tool supports this), (3) paid tools like Ahrefs or SEMrush. Exact numbers require paid tools, but free tools work well for relative comparisons.Check search volume
Does rewriting content improve SEO?
Yes, when done properly. Effective rewrites: (1) align content with search intent, (2) update with latest information, (3) add missing information, (4) improve readability and structure. Simply adding words or stuffing keywords is counterproductive. Prioritize pages with high impressions but low clicks in Search Console.Read the content rewrite guide
What are the risks of duplicate content?
Duplicate content makes it hard for Google to determine which page to show in results, potentially displaying the wrong page or diluting ranking signals. Manual penalties apply only to malicious duplication, but technical duplicates (www variants, parameters, HTTP/HTTPS) still cause signal dilution. Fix with canonical tags and 301 redirects.
What is search intent?
Search intent is the purpose behind a user's search query, classified into four types: (1) Know — seeking information (e.g., 'what is SEO'). (2) Do — wanting to take action (e.g., 'SEO score checker'). (3) Go — navigating to a specific site (e.g., 'Search Console login'). (4) Buy — considering purchase (e.g., 'SEO tools comparison'). Aligning content with search intent is the single most important factor for ranking.
Does longer content rank better?
Word count is not a Google ranking factor. What matters is having sufficient information to satisfy search intent. Writing 5,000 words for a query answerable in 1,000 adds noise and degrades user experience. Top-ranking pages' word counts are a correlation, not causation. Aim for the shortest content that fully satisfies the search intent.
How do internal links help SEO?
Internal links connect pages within your site and serve three functions: (1) Crawl facilitation — crawlers discover pages through internal links. (2) Link equity distribution — ranking signals flow through links. (3) User engagement — increases pages per session. Best practices: link between topically related pages, use descriptive anchor text with keywords, and concentrate more internal links on your most important pages.
How do I find my competitors' keywords?
Three main methods: (1) Competitor keyword tools — enter a URL to see which keywords competitors rank for. Our tool lets you extract competitor keywords for free. (2) Use Google's 'site:' command to search a competitor's indexed pages and identify keyword patterns. (3) Compare your Search Console data with competitors to find content gaps — keywords they rank for but you don't. Competitor analysis is the most efficient way to discover new content topics.Research competitor keywords for free

Structured Data(5)

What is structured data (JSON-LD)?
Structured data is markup that helps search engines understand web page content programmatically. JSON-LD is the most recommended format, written inside <script type="application/ld+json"> tags. Structuring FAQs, products, reviews, and events increases the chances of rich results (star ratings, FAQ sections) in search results.Read the structured data guide
How can I verify my structured data?
Three methods: (1) Google's Rich Results Test (search.google.com/test/rich-results) — check detected schemas and errors. (2) Schema.org Validator (validator.schema.org) — check JSON-LD syntax. (3) Chrome DevTools console — run document.querySelectorAll('script[type="application/ld+json"]'). Our tool also auto-checks structured data during SEO diagnosis.Diagnose structured data for free
What are the benefits of FAQPage structured data?
FAQPage structured data can trigger FAQ rich results — expandable Q&A sections in search results that increase your real estate and CTR. AI Overview (AIO) also tends to prefer FAQ-formatted information. Note: per Google guidelines, FAQs in JSON-LD must also be visible on the page.
Which schema types should I implement?
Depends on site type. Business: Organization + WebSite + FAQPage. Blog: Article + BreadcrumbList. E-commerce: Product + Offer + AggregateRating. SaaS/Tools: SoftwareApplication + Offer + FAQPage. Start with WebSite + Organization + BreadcrumbList as basics, then add site-specific schemas.
Why isn't my structured data showing in search results?
Four common reasons: (1) JSON-LD syntax errors — validate with Google's Rich Results Test. (2) Guideline violation — content defined in JSON-LD must also be visible on the page; hidden content gets ignored. (3) Crawl/index delay — Google needs days to weeks to re-crawl after implementation. Request indexing via Search Console's URL Inspection to speed this up. (4) Google's discretion — even valid structured data doesn't guarantee rich results; display is ultimately Google's decision.Diagnose structured data for free

Technical SEO(10)

What are Core Web Vitals?
Core Web Vitals are three Google-defined metrics for user experience. LCP (Largest Contentful Paint): main content load speed, good under 2.5s. INP (Interaction to Next Paint): responsiveness, good under 200ms. CLS (Cumulative Layout Shift): visual stability, good under 0.1. These are confirmed Google ranking factors.Read the Core Web Vitals guide
How can I improve page speed?
Priority optimizations: (1) image optimization (WebP/AVIF, proper sizing, lazy loading), (2) reduce/defer unnecessary JavaScript, (3) CSS optimization (remove unused CSS, inline Critical CSS), (4) use a CDN, (5) improve server response time. Measure with Google PageSpeed Insights and address flagged items in order.Measure Core Web Vitals
What is mobile-friendliness?
Mobile-friendliness means pages are optimized for smartphone viewing. Google uses Mobile-First Indexing (MFI), ranking based on mobile page versions. Requirements: responsive design, tap-friendly buttons (48px+), readable font size (16px+), and proper viewport configuration.
How should robots.txt be written?
robots.txt controls crawler access at the site root. Basic structure: User-agent: (target crawler) and Disallow: (blocked paths). Allow all: 'User-agent: * / Allow: /'. Block admin: 'Disallow: /admin/'. Include Sitemap: with your XML sitemap URL. Note: robots.txt is a request, not enforcement.
Is an XML sitemap necessary?
Not required but strongly recommended, especially for new sites, large sites, and complex link structures. Submitting to Search Console helps Google discover and index pages faster. Most frameworks auto-generate sitemaps. Include lastmod tags for frequently updated pages.Read the XML sitemap guide
Is HTTPS mandatory?
Effectively yes. Google uses HTTPS as a ranking signal, and browsers show 'Not Secure' warnings for HTTP. Free SSL via Let's Encrypt makes cost near zero. When migrating, set 301 redirects for all pages and add HTTPS property in Search Console.
What is the difference between noindex and nofollow?
noindex: 'don't show this page in search results' — for admin pages, internal search, duplicates. nofollow: 'don't pass PageRank through this link' — for ad links, user-generated content. They serve different purposes and should not be confused.
What is the difference between 301 and 302 redirects?
301 means 'permanently moved,' 302 means 'temporarily moved.' The key SEO difference: 301 transfers link equity to the new URL, while 302 generally does not. Use 301 for domain changes, URL restructuring, and HTTP-to-HTTPS migration. Use 302 for temporary maintenance pages or A/B tests. Using 302 when you mean 301 loses accumulated page authority on the new URL.
How should I handle pagination for SEO?
For paginated pages (/page/1, /page/2...), link all pages with internal navigation and set unique titles/descriptions for each. Google discontinued rel="prev/next" as a signal in 2019. Current best practices: (1) keep all pages crawlable, (2) don't canonicalize all pages to page 1, (3) structure navigation so users can easily find what they need.
How do I handle multilingual SEO?
Three essentials: (1) Use hreflang tags to cross-reference language versions so the right language appears for each user. (2) Include language codes in URLs (example.com/en/, example.com/ja/). (3) Create unique titles, meta descriptions, and OGP for each language. Low-quality machine translations can hurt rather than help — start with high-quality translations for key pages and expand gradually.

Google Search Console(5)

What should I check first in Search Console?
Start with the Search Performance report's 4 metrics: (1) Total clicks — actual site visits, (2) Total impressions — search result appearances, (3) Average CTR — click-through rate, (4) Average position. Keywords with high impressions but low CTR are prime candidates for title/description optimization.
What if my page isn't being indexed?
Check the Page Indexing report for causes. Common issues: (1) 'Discovered - not indexed' — low crawl priority; add internal links and include in sitemap. (2) 'Crawled - not indexed' — deemed low quality; improve content. (3) 'Excluded by noindex' — check for unintended noindex tags. Use URL Inspection to request individual indexing.
How do I read the Search Performance report?
Analyze across 4 dimensions: Queries, Pages, Countries, Devices. Practical tips: (1) Sort queries by impressions, find low-CTR keywords to improve titles/descriptions. (2) Check each page's actual search queries vs intended keywords. (3) Compare periods to monitor monthly changes. Data is stored for up to 16 months.
How do I submit a sitemap in Search Console?
Go to 'Sitemaps' in the left menu, enter your sitemap URL (typically /sitemap.xml), and click 'Submit.' If it shows 'Success,' it's been processed. Errors will show details for you to investigate. Once submitted, Google automatically re-fetches updated sitemaps. Large sites should use a sitemap index file (a file that lists multiple sitemaps).
What if I receive a manual action (penalty)?
Check under 'Security & Manual Actions' > 'Manual Actions' in Search Console. Resolution steps: (1) Identify the issue (unnatural links, thin content, spam). (2) Fix the problem (use the Disavow Links tool for unnatural links). (3) Submit a 'Reconsideration Request' via Search Console. (4) Wait for Google's review (typically days to weeks). Be specific about what caused the issue and what you fixed.

AIO / GEO(7)

What is AI Overview (AIO)?
AI Overview (AIO) is an AI-generated answer at the top of Google search results. AI extracts and summarizes information from multiple pages. Being cited provides top visibility even with low organic rankings. Per Ahrefs, 62% of AIO citations come from outside the organic top 10.Read the AIO citation analysis
What is GEO (Generative Engine Optimization)?
GEO optimizes your site to be cited by AI-powered search engines (Google AIO, Bing Copilot, Perplexity). This includes structured data, direct answers at page top, specific numbers, and structured FAQs. GEO isn't special — it's thorough, good SEO. Requirements for structured, clear, extractable information align with traditional SEO.
What is llms.txt?
llms.txt helps LLMs understand your site. If robots.txt is for crawlers, llms.txt is for AI. Place it at site root with service overview, features, pricing, and differentiators in markdown. Enables AI to grasp your site from a single file, potentially contributing to AIO citations.Read the llms.txt guide
What makes a page likely to be cited in AIO?
Four characteristics: (1) Direct answer to search intent at page top (55% of AIO citations from top 30% per Seer Interactive). (2) Properly implemented structured data. (3) Information with specific numbers in list format. (4) Clear differentiation points. All align with SEO best practices.
How can I check if AIO is showing for my keywords?
Currently, the only reliable method is manually searching your target keywords on Google and visually checking for AI Overview. Google Search Console does not have an AIO-specific filter or report, and no automated tool accurately tracks AIO citations. Periodically search your key terms and note whether AIO appears and which sources are cited.
Do I need separate strategies for Perplexity and other AI search engines?
No. Perplexity, Bing Copilot, ChatGPT search, and other AI engines all share the same fundamentals for citing web content: (1) structured data, (2) clear answers to search intent, (3) trustworthy information, (4) llms.txt. Rather than optimizing for each platform individually, focus on content quality and structure — the same GEO principles apply universally.
How do I measure the impact of being cited in AIO?
Precise AIO traffic measurement is currently limited. Indirect methods: (1) Compare CTR changes for target keywords in Search Console over time. (2) Monitor organic traffic trends in GA4. (3) Track branded search volume changes. AIO citations may be consumed without clicks, so look beyond direct traffic — brand awareness indicators like branded search growth are equally important.
