On Page SEO Analysis: the On Page SEO Checker for Pages You Already Published

Most on page SEO checkers grade against a fixed rulebook: keyword in title, keyword density, word count, one H1. Those rules are table stakes and they miss the thing that decides rankings. Search results are relative. Your page is not competing against a checklist, it is competing against nine other pages that already answer the query. So Reoptimize scores both layers.

Paste a URL and its target keyword into the analyzer at the top of this page to see the shape of the output. For a portfolio view rather than a single page, run the content decay checker across your sitemap.

1. Confirm the target keyword. One page, one primary query. If you cannot name it, the page cannot be scored.
2. Read the live SERP like an editor. Open the top five results. What question are they answering, in what order, in what format? That is the bar.
3. Check the title against intent, not length. A 52-character title that promises the wrong thing loses to a 61-character title that promises the right thing.
4. Map the outline. List your H2s next to the H2s of the ranking pages. Missing sections are the fastest ranking gains available.
5. Find the entity gap. Terms, tools, and named concepts the top pages treat as required reading and your page never mentions.
6. Count inbound internal links. A page with two internal links from a 300-page site is under-supported no matter how good the copy is.
7. Check schema and freshness. Ship the structured data the page qualifies for and update anything that dates the page.

Done by hand this is 2 to 4 hours per page, which is why most libraries never get the pass. The analyzer compresses steps 2 to 6 into minutes and writes each finding as a before and after suggestion your writer can execute. The full method is on how it works.

A score is only useful if it maps to work. Reoptimize scores a page from 0 to 100 against the current top-ranking set for its keyword, and the number moves for reasons you can act on. Pages in the 70s and 80s are usually competitive and need targeted additions. Pages in the 40s and 50s are typically missing whole sections, not commas. Anything under 40 for a keyword you care about is usually an intent mismatch: the page answers a different question than the one being searched, and no amount of on-page tuning fixes that. Rewriting the angle does.

Do not chase 100. A perfect score on a page nobody links to and nobody searches for is a vanity number. Chase the fixes on pages with traffic history, which is exactly what the content audit tool queues up for you.

Honest limits. On page work moves pages that are close: something ranking 6 to 20 that used to rank higher, or a page competing on a query where the top results are not much stronger. It will not push a page into a SERP owned by domains with hundreds of referring pages you do not have. It cannot fix a page that targets a keyword your site has no business ranking for. And it cannot promise a position, because no tool can.

What it does reliably is remove every reason for the page to lose that is inside your control. On a library of a few hundred pages, that alone tends to be the cheapest organic growth available, because the URLs already have age, links, and history. If your traffic fell off a cliff rather than drifting down, start with recovering lost SEO traffic instead: cliffs are usually technical or algorithmic, not on-page.
