Website SEO Score Checker

The earned points from all checks are added together and clamped to a 0–100 scale, then mapped to a letter grade: A from 90, B from 80, C from 70, D from 55, and F below that. Because the checks are weighted, fixing a missing title or restoring indexability moves the number far more than adding a favicon. The result also surfaces a short, ranked list of priority fixes, ordered by how many points each gap is costing you.

Not every check is worth the same. The title tag carries up to twelve points, with full credit when the title runs roughly 30 to 65 characters and reduced credit when it exists but sits outside that range. The meta description, image alt coverage, and content depth are each worth up to ten points — the description scores in full at about 70 to 165 characters, alt coverage scales directly with the percentage of images that have alt text, and content depth steps up at roughly 100, 300, and 600 words. HTTPS, a single clear H1, the viewport tag, and indexability are each worth eight points.

The lighter checks fill in the rest: a canonical tag and supporting H2 subheadings, an Open Graph title, JSON-LD structured data, an HTML lang attribute, and a declared favicon each contribute a smaller share. Because the weights differ this much, restoring a missing title or fixing an accidental noindex moves the number far more than adding a favicon — which is exactly why the priority-fix list is ordered by the points each gap is costing you.

Start at the top of the priority-fix list, since it is already sorted by impact — the items there are the cheapest points on the board. Confirm the page is indexable before anything else, because an accidental noindex both zeroes a high-weight check and, more importantly, keeps the page out of search entirely. Aim your title and meta description at their full-credit ranges rather than just making sure they exist, and raise alt coverage by writing genuine descriptions for meaningful images instead of stuffing keywords. Remember that content depth is a blunt word-count signal: clearing the 600-word tier earns the points, but it is no substitute for actually answering the searcher's question well.

This number is a triage aid, not a Google ranking and not a promise of one. It looks only at on-page markup and deliberately ignores off-page factors such as backlinks, domain authority, search intent, and how competitors are doing for the same query. A page can score in the nineties here and still rank poorly if the content does not match what searchers want, and a lower score simply points to fixable on-page hygiene. Treat it as a weighted checklist, then judge content quality and relevance separately.
