常见问题
What does the SEO Optimizer actually check?
It analyses your content for keyword density and placement, readability level, and on-page signals like heading structure and length, then returns specific suggestions to improve each area. The goal is concrete edits, not a vague score.
How do I use it on a draft?
Paste your content and, if you have one, the target keyword you want the page to rank for. It evaluates how well the text supports that keyword and where readability or structure is holding it back, then lists the changes to make.
Does a good score here guarantee I'll rank on Google?
No. On-page optimisation is one ranking factor among many, alongside backlinks, site authority, search intent, and competition. The tool helps you fix what's in your control on the page; it can't promise a position in the results.
What's an ideal keyword density?
There's no magic number, and stuffing keywords hurts. The optimizer flags when a term appears too rarely to signal relevance or so often it reads as spam, and nudges you toward natural usage with supporting variations instead.
Can it optimise content in languages other than English?
It works best on English-language copy, where readability scoring and keyword analysis are most reliable. For other languages the keyword checks still apply, but treat the readability score as a rough guide.
Will it rewrite my content for me?
It focuses on analysis and recommendations rather than wholesale rewriting, so your voice stays intact. You apply the suggested edits, which keeps you in control of tone and accuracy.
Is there a limit on how much I can analyse?
Free use covers 5 analyses per day with no signup. If you're optimising many pages or a whole site, Pro removes the limit at $19/month.
