A UK SEO

Anchor text is the text used in a link, for SEO it’s important that links contain relevant anchor text, as in the text needs to be relevant to the page the link points to. For example

Click here to see our products range.

“here” means nothing to the search engines. Where as.

View our products range.

Now the link is meaningful so the search engines will understand that the page they will craw to is the products page.

This method should apply to internal and external links.
