Basic SEO FAQ

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 →

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 →

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 →

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 →

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 →

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 →

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.

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.
