    "; echo "关键词密度:".$keyword_density."%"; ?>
    Copy after login
    1. Internal links and anchor text

    Appropriately adding internal links to the article can improve the ranking of keywords in search engines Weights. At the same time, we also need to add appropriate anchor text to the link so that search engines can understand the content of the link.

    Sample code:

    关键词是关键的部分"; $content_with_link = str_replace($keyword, "".$keyword."", $content); echo $content_with_link; ?>
