Score readability, structure and SEO signals in your content.
The Content Analysis tool measures readability, structure and keyword presence in any article — pasted as text/HTML or pulled from a live page URL.
It is a quick pre-publish sanity check for word count, sentence length, reading level and keyword density.
Enter your draft text or fetch the page you want to evaluate.
List the keywords the page should rank for, comma separated.
Review the metrics and the actionable list of improvements.
Built and maintained by the W3Tech team that ships production websites and SEO campaigns every week, this tool is held to the same standard we use on our own client work.
These tools run in real W3Tech SEO projects, where the numbers feed actual client rankings and link building.
The recommendations mirror what our SEO team implements on live sites every week.
Checks run against live inputs on demand rather than stale, pre-computed databases.
The same data pros use, presented without the gatekeeping.
Every result is something you can act on — markup to paste, files to upload, scores to compare.
Run up to 10 URLs or a full sitemap list in a single pass.
No accounts, no email capture, no trial countdown.
No premium tiers holding the useful data hostage.
Most tools return results faster than you can refill a coffee.
Competitor lists, sitemaps and URL batches are handled in one go.
Run as many checks as your audit demands — nothing is capped.
Ranking is decided by signals: technical health, content relevance, authority and speed. These tools target every one of them — markup you can validate, crawl files you can submit, authority you can compare and density you can sanity-check.
The sites that outrank consistently are not the ones with a single clever win. They are the ones that stay disciplined across the whole checklist. That is precisely what this suite enforces.
Run competitor URLs through the checker and sitemap tools to understand their on-page setup.
Compare authority, density and structure to spot where they are most beatable.
Turn what the tools reveal into a prioritized change plan and ship it faster than they react.
Most professional SEO software costs hundreds of dollars a month — the same money small businesses should be spending on their product. W3Tech built these tools for its own client work and is releasing them free to level the playing field.
Our mission is to give every business access to the same analysis the pros use, without the gatekeeping, sign-ups or premium pricing.
For the web, 60-80 is comfortable for most readers. Below 50 starts to get heavy for a general audience.
There is no hard rule. Write naturally and include the keyword and natural variations; forcing density past 1-2% rarely helps.
