Paste a draft and see the SEO and readability problems immediately — keyword density, sentence length, passive voice, transitions and heading structure. Your text never leaves this page.
Start typing and the analysis appears here — instantly, and without your draft leaving the browser.
A real-time content checker scores a draft while you write it. Paste your text, add the keyword you want the page to rank for, an SEO title, meta description and URL slug, and the score updates as you edit.
It checks the things a search engine and a reader notice first: whether the topic is clear from the title, headings and introduction, whether the keyword is used naturally, and whether the text is easy to read.
Every change re-runs the checks in your browser. Nothing is sent to a server, so drafts stay private.
Whether your keyword appears in the introduction, a heading, the SEO title and the slug, and whether it is repeated so often that it reads as stuffing.
Whether the SEO title and meta description are set and fit the space Google usually shows (about 60 and 160 characters).
A Flesch reading-ease score and your average sentence length, so long, dense passages stand out before a reader meets them.
Fixing a draft is cheaper than fixing a live page: there are no old URLs to update and nothing to wait for search engines to re-crawl.
The checks cannot tell whether the content is accurate or genuinely helpful. Use them to catch the mechanical problems, then read the draft as your reader would.
This tool checks one draft you paste. A site audit crawls the pages already published and finds technical problems such as broken links, missing titles and redirect chains.
Anyone who writes for the web:
Checking a page before it goes live, without hiring an agency.
A consistent checklist for every draft, whoever writes it.
One shared standard for titles, descriptions and keyword use across a team.
Scroll up, paste your content and add your keyword to get instant feedback.
Common questions about the content checker.
Content length, keyword density, whether your keyword appears in the introduction, headings, SEO title and URL slug, the length of your SEO title and meta description, readability and average sentence length.
The checks are simple rules applied consistently, so they are reliable for what they measure, such as lengths, counts and where your keyword appears. They cannot judge whether the content is correct, original or genuinely useful; that still needs a human read.
There is no ideal percentage. Write for the reader and use the keyword where it fits naturally. The checker flags a keyword missing entirely or repeated so often (above 2.5%) that it reads as stuffing.
No. The analysis runs in your browser, so the text you paste is not sent to seodada or stored.
Run the same checks against any published URL, or crawl up to 200 pages for the issues a single page can't show you.
