How is this different from rank tracking?

Rank tracking tracks the ranking changes of your own specific keywords over time. Competitor keyword research comprehensively retrieves the list of keywords competitors rank for. The former is a monitoring tool; the latter is an exploration tool.

How accurate is ETV (estimated traffic)?

ETV is an estimated value calculated from search rank, estimated CTR, and monthly search volume. Absolute values do not perfectly match actual traffic, but the accuracy is sufficient for comparing "relative strength" between competitors. It is practical enough for priority decisions.

Can I filter and sort the results?

Yes. All columns — search volume, rank, ETV, and so on — are click-sortable. The number of displayed items is also filterable by top-N count, so you can quickly reach the keywords you care about.

Can I download the results as CSV?

Yes. CSV download of research results is available on the Basic plan and above. Useful for analyzing in spreadsheets or pasting into client proposal materials.

Competitor keyword research is a method that, by simply entering a competitor's domain, retrieves the keywords, search rankings, estimated traffic, and ranking page URLs that the competitor ranks for on Google — helping you discover content gaps on your own site. Unlike the large-scale analyses of Ahrefs and Semrush, it instantly visualizes "which keywords your competitors are winning with" at a price point designed for freelancers and SMBs.

3 Steps to Build a Content Strategy with Competitor Keyword Research

Enter a competitor domain and the list returns within tens of seconds. Use the flow below to identify content gaps.

1
Identify the top-ranking competitor domains for your target keyword
Search Google for your target keyword and pick 2-3 sites from the top 3-6 results that are content-oriented and operate in the same industry and at a similar scale. Exclude ads and major aggregator sites.
2
Retrieve the competitor's ranking keywords as a list
Enter the chosen competitor domain and display a list of ranking keywords, search positions, monthly search volume, estimated traffic value (ETV), and the ranking page URLs. Sort by search volume in descending order to identify the competitor's traffic pillars.
3
Extract content gaps and turn them into a plan
Extract keywords your site is not ranking for. Prioritize articles where ETV is high and the topic matches your area of expertise. Clustering by search intent makes the planning efficient.

Comparison items	CodeQuest.work SEO (practical scope)	Ahrefs / Semrush (large scale)
KW database scale	Measured data from live Google searches	Proprietary DB with millions to billions of entries
Data fields	Keyword, rank, search volume, ETV, ranking page URL	Above + total traffic, history, related keyword tree
Results displayed	Free 3 / Entry 5 / Basic 20 / Pro 100 per query	Unlimited (plan-dependent)
Monthly searches	Free 3/mo, Entry 10/mo, Basic 30/mo, Pro 100/mo (shared with Ranked Keywords)	Unlimited to thousands

FAQ

What is competitor keyword research?▾

Enter a competitor's domain to see their Google-ranked keywords, search positions, monthly search volumes, estimated traffic, and ranking page URLs in a single view.

What data can I retrieve?▾

Keyword name, search rank, monthly search volume, estimated traffic value (ETV), and the specific page URL ranking for each keyword. Click column headers to sort.

How is this different from Ranked Keywords?▾

Ranked Keywords is primarily for checking your own site's rankings. Competitor Keywords lets you enter a competitor's domain to discover which keywords and pages they rank for, including ranking page URLs.

Are there usage limits?▾

Available on all plans, sharing the usage quota with Ranked Keywords. Free: 3 searches/mo (top 3 results), Entry: 10/mo (top 5), Basic: 30/mo (top 20), Pro: 100/mo (top 100).

How should I use the results?▾

Identify keywords where competitors rank but your site has no content. Use search volume and estimated traffic to prioritize which keywords to target for new content.

How does this compare to Ahrefs or Semrush?▾

Ahrefs and Semrush offer extensive keyword databases at $100+/month. Our tool provides competitor keyword research at a freelancer-friendly price, plus integrated SEO diagnosis and automatic improvement code generation.

How long does it take to retrieve the data?▾

Results return in tens of seconds to about a minute per domain. Because it crawls search results and aggregates data, it takes a little longer than a pre-built database query like Ahrefs.

How fresh is the data?▾

Because Google search results are crawled in real time, the data reflects the current ranking situation on the day of the query. It is fresher than tools whose database is updated monthly.

How is this different from GSC data?▾

GSC only covers "the search performance of your own site." This tool is decisively different in that it lets you retrieve "the search performance of other companies' sites." Using both together lets you simultaneously understand your room for improvement and your competitors' strategy.

Can I also research English-language and multilingual sites?▾

Yes. Because it is based on Google search, you can research sites in any language or region where Google provides search results, including English and Japanese. It can also be used for competitor analysis of international SEO and multilingual rollouts.
