How high is maximum keyword density please? I've been told 6-9% is ideal. Does this change if there is more text?

I don't worry with keyword density

Do not worry too much about this matter and try creating your web pages in a natural way.

It is always advised to develop a content for human not for search engines. Having high keyword density as like 9 % may result into high bounce rate which can harm your ranking as well. 2-5 percent is good enough

Yes, keep it at a low (2-6%) rate so it wont be keyword stuffing (spamming).

The main thing is that your keywords should be relevant to the site, describing your site, there isn't a limit of use of keywords, as long as you don't spam or stuff kws..

Try to concentrate on only 1 or 2 keywords for page. Incorporate them into you page title, meta tags, H1 tag (only 1) and the first hundred words of copy.

Hello,

It's depending on website, But 3 to 6 % is better.

with regards,

That's a good range. More than that is spammy

Ah I see most say it's around 2-6%.
Seems to make sense.

Keep between 3 - 5%. If you go more than that you can lower your rank.
