What is on-page SEO?
On-page SEO is the set of signals inside a page that help search engines understand and rank it. That includes the title, the heading structure, the meta description, how often the target keyword appears, and how readable the writing is. Unlike off-page factors such as links, these are all things you control directly.
An on-page SEO checker reviews a page against those signals and reports what is in good shape and what needs work. Enter your blog URL and keyword here and you are taken to the Wittypen app to run the full audit.
The checker crawls your page and returns a scored report with actionable suggestions so you can fix issues before they cost you rankings.
Why on-page SEO matters
01
It catches the basics
A missing title, no H1, or a thin word count are common issues. A quick check surfaces them before a page goes live.
02
It keeps keywords in balance
Too little use of the target keyword can weaken relevance; too much reads as stuffing. A density figure helps you stay in range.
03
It protects readability
Long, dense sentences slow readers down. An average sentence length hint flags writing that may need tightening.

Frequently asked questions
Can this checker crawl a live URL?
Yes. Enter the blog URL and keyword, then submit to run the check on app.wittypen.com. The app fetches the page and returns a full on-page SEO report.
What is a good keyword density?
There is no fixed rule, but a density of roughly 0.5 to 2.5 percent is a common comfortable range. The goal is natural use, not a target number. If the keyword feels repetitive to read, it is too high.
How many words should a page have?
It depends on the topic and intent. Many ranking pages run well past 600 words because they cover a subject thoroughly, but a short, focused page can rank if it fully answers the query.
What meta description length should I aim for?
Aim for 150 to 160 characters. The checker flags descriptions that are missing or fall outside that range, since longer ones get truncated in search results.
Does the checker store my URL?
The check runs on app.wittypen.com. See the Wittypen privacy policy for how data is handled on the app.
