SEO Content Analyzer
Check how well a page’s content is set up for readers and search engines. The analyzer finds the main content area, counts words and sentences, measures the title and meta description in pixels, checks the H1 and subheadings, paragraph and sentence length and estimated reading ease, and lists the most used words and two-word phrases. Enter a focus keyword to see whether it appears in the title, H1, description, first 100 words, subheadings, URL and image alt text, and how dense it is.

SEO Content Analyzer FAQ
Is there an ideal word count?
No. Google has said word count is not a ranking factor. Pages with very little text, however, rarely answer a search fully, so the tool warns below about 300 words.
What keyword density should I aim for?
There is no ideal number. Write naturally; above roughly 3% exact-match density the text usually reads as stuffed, which the tool flags.
How is reading ease calculated?
With the Flesch formula from sentence length and syllables per word. Syllables are estimated with English rules, so the score is only shown for English pages.
Does the score predict rankings?
No. It checks on-page basics. Relevance, expertise, links and user satisfaction matter more.
What the analyzer looks at
On-page SEO starts with the basics: a descriptive title that fits in the results, a meta description that invites the click, one clear H1, subheadings that break the text into sections and paragraphs that are easy to read on a phone. Each of these is checked and explained.
The focus keyword checks count exact phrase matches. Search engines understand synonyms and variations, so do not force the exact phrase everywhere; use the checks to make sure the topic is clear in the most visible places.
The top words and phrases show what the page is really about to a machine reading it, which is a quick way to spot off-topic sections or missing subtopics.
Privacy: the address you enter is fetched by our server only to run this check. The downloaded HTML is passed to your browser for analysis and is not stored, and the results are not saved on our side. Requests are rate-limited to keep the service fair for everyone, so if you check many pages in a row you may need to wait a few minutes.
Limits: pages are read up to 2 MB of HTML, redirects are followed up to eight hops and each request has a short timeout. Pages behind a login, servers that block automated requests and content added only by JavaScript cannot be analysed this way; for those, copy the page source from your browser and use the paste option where it is available.
Tip: fix the problems marked red first, because they matter most. Yellow warnings are worth reviewing but are often harmless in context, and blue notes are information. After a change, run the check again to confirm the result – search engines pick up the change on their next visit to the page.
