MeasureSEO vs Website SEO Checker (2026): which should you pick?

Pick MeasureSEO if

• Fits if you check a draft or live page for a keyword used too often
• Works for writers on pages in languages other than English, with stop-word lists for 25+

Look elsewhere if

• Too light for keyword research, as it gives no search volumes or rankings
• Watch out: pages built mostly with JavaScript, such as forums and web apps, are harder for it to read
• Skip it if you're not on Chrome, and note the extension's last update was in December 2023
• Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply

Pick Website SEO Checker if

• Fits if you check a page's tags, indexing rules and hreflang without opening its source
• Works for Sitechecker users who want a page's Search Console clicks and queries beside it

Look elsewhere if

• Too light for whole-site audits, as it checks one page and site crawls are a separate Sitechecker product
• Tight if you won't make a Sitechecker account, since Search Console figures and monitoring need one
• Not for you if you browse in Firefox, Safari or Edge, as it's listed for Chrome only
• Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply

MeasureSEO

• Pages built mostly with JavaScript, such as forums and web apps, are harder to analyze, the listing says.
• It counts words on one page; it gives no search volumes or rankings.
• It is listed for Chrome only, and the listing was last updated on December 17, 2023.
• The developer has not identified itself as a trader, so EU consumer rights do not apply, as the store listing notes.

Website SEO Checker

• It checks one page at a time; whole-site crawls are a separate product on the Sitechecker platform.
• Search Console insights and issue monitoring work only when logged in to a Sitechecker account.
• It is listed for Chrome only.
• The Chrome Web Store notes the developer has not identified itself as a trader, so EU consumer rights do not apply.

MeasureSEO

Keyword counts and density

Lists every keyword on the page with how many times it appears and its percentage of the total word count, shown above the table.

Phrase length and minimum count

Switch the table between single words and longer phrases, and hide terms that appear fewer times than a set minimum.

Stop words in 25+ languages

Stop words are removed by default using lists in more than 25 languages, and you can add your own stop words or excluded words.

CSV export

Export the keyword table to CSV for reporting or further analysis.

Runs in the browser

The analysis happens in your browser without uploading page text, and the developer discloses that it collects no data.

Web tools

The MeasureSEO site has a keyword density checker for pasted drafts, plus robots.txt, meta tag, sitemap and UTM generators.
