Hello,

In my web site my Meta Name Keywords are 3000 bytes long.
How it is possible to respect the SEO recommandations ?

Thanks in advance.

The bytes? To my knowlegde if the length of the text is limited. Limited in terms of text being used to that extent. In any case: The meta keywords don't play any significant role for search engines anymore. Google as the most important one does ignore them anyway. Much more important ist the content of the page itself.

In general, the keywords use the tags assigned to the item in question. So the quick fix is assign less.
