SEO Tools

SEO tools for the on-page work that an editor or content operator can finish without involving an engineer: title and meta description length checks, keyword density and prominence scoring, product listing optimization against marketplace character limits, and the small structural validations that catch the silly mistakes (no H1, duplicate H1s, missing alt text, an h-tag jump from h2 to h4). The work here is verification and tuning, not strategy. The common assumption to unlearn is that the meta description length is measured in characters; Google truncates by pixel width on the rendered SERP, which is why the length checkers here report both characters and pixel width and flag the latter as the binding constraint. A second common mistake is over-stuffing keywords; the keyword tools surface density, prominence, and co-occurrence, and the recommended ranges are conservative on purpose. If you are new to the category, start with the length checkers before any page goes live, the keyword tools when you are revising older content for a new target term, and the listing optimizers if you sell on Amazon, eBay, Etsy, or any marketplace that constrains your fields. None of the tools here promise rankings; they catch the on-page mistakes that would otherwise cost rankings.
