Free Keyword Research Tool

Enter a topic to see its estimated monthly searches, keyword difficulty, CPC and search intent, then explore related keyword opportunities and question ideas for your next article.

Your search query is sent to WriterFlowLab's server and our SEO data provider (DataForSEO) to return these results. It is not added to the page address or sent to analytics.

Search volume, CPC and difficulty are estimates and may differ from Google Ads, Search Console or other SEO platforms. Keyword data is supplied by DataForSEO, a third-party SEO data provider.

How to use the keyword research tool

  1. Enter a short topic or phrase, such as "content calendar" or "email newsletter ideas".
  2. Choose the country (and language, where a country has more than one) you are writing for. Search volumes differ a lot between countries.
  3. Review the overview for your seed keyword, then sort or filter the related keywords by volume, difficulty or intent.
  4. Shortlist keywords that match what your audience actually wants, then check the live results with the SERP Checker before you write.

What the metrics mean

  • Search volume: an estimate of average monthly Google searches for the keyword in the selected country, based on recent months.
  • Keyword difficulty (KD): DataForSEO's 0–100 estimate of how hard it is to reach the top 10 organic results. Higher is harder. It is a guide, not a guarantee.
  • CPC: the average cost per click advertisers have paid for the keyword in Google Ads, in US dollars. A high CPC often signals commercial value.
  • Paid competition: how competitive the keyword is for advertisers (low, medium or high). It describes ads, not organic rankings.
  • Search intent: the main reason people search: informational (to learn), commercial (to compare), transactional (to buy or sign up) or navigational (to find a specific site).

Limitations

  • Search volume, CPC and difficulty are estimates and may differ from Google Ads, Search Console or other SEO platforms.
  • Very new or very niche keywords may have no data, which is shown as a dash rather than a guessed number.
  • Question keywords are picked out of the returned results by their wording and are only shown for English searches.
  • Free searches are limited per day. Export is not offered, but you can copy the keyword list.

Privacy and your data

  • Unlike our browser-only writing tools, this tool needs a server: the keyword you enter is sent to WriterFlowLab's server and to DataForSEO, our SEO data provider, to return these results.
  • The keyword is not added to the page address, saved in your browser or sent to Google Analytics. Our analytics only record that a search happened, which tool was used and the country selected.
  • Results are cached on our server for up to seven days so that repeating the same search does not request the data again. The cache holds the keyword with its results and is deleted when it expires.
  • To apply the free daily limit, our server keeps a one-way hashed version of your IP address (not the address itself) for up to three days. No account or email address is needed.

Like the rest of the site, this page also uses Google Analytics and Google AdSense, as described in our privacy policy.
