Step 1: run a free check
Paste your URL into the free SEO checker and hit Analyze. In about thirty seconds you get a score out of 100 plus the specific issues found: no signup, no email required to see the result. Test your most important page first — usually the homepage or your top landing page — since scores are per-page, not per-site.
Step 2: read the score correctly
A score of 90+ is excellent and 70+ is genuinely solid on a demanding scale. But the number depends entirely on what's checked: a permissive tool that only inspects your title tag hands out 95s freely, while a strict one that weighs indexability, canonical tags, structured data and heading structure is much harder to satisfy.
Also know what no SEO score can see: backlinks, domain authority and your actual rankings are off-page factors invisible to a page scan. Treat the score as a checklist of what you control on the page — not a prediction of where you'll rank.
Step 3: fix the highest-impact items first
The fixes that move a score (and results) fastest, in order: make sure the page is indexable at all (no stray noindex, a reachable sitemap); write a unique 30–60 character title with your keyword near the front; add a 120–158 character meta description; keep exactly one H1 and a logical heading outline; add JSON-LD structured data; and declare a canonical URL.
These are the items a checker can verify objectively — and the ones Google's own documentation keeps pointing back to.
Step 4: check the dimensions SEO tools skip
Classic SEO checkers stop at on-page tags, but rankings increasingly depend on more: page speed and Core Web Vitals, accessibility, security headers, and now AI-search readiness. WebAnalyzer scores all of these alongside SEO — including a GEO score measuring whether ChatGPT and Perplexity can read and cite you — so one report covers the whole picture.
Re-check after each round of fixes. The before/after delta, on the same tool, is the only score comparison that means anything.
