Hello guys.... If i write a simple text john and then write john as a anchor text for a link. then google gives importance to john or john anchor text.
both will be given same importance except that anchor text will be followed and the page it refers to will be indexed. moreover, if you build significant amount of links with the keyword "john" then you will be ranked for this keyword.
That's right, the more backlinks you have that are targeted to your keyword, will help to increase your SERP! You can use this for blog commenting, forum posting, links in bios on article directories, the list goes on!
i think you better know this as you have the one in the signature........still if you really dont know this then an anchor text is better to than a simple text......as it help you get link to your website or a hyperlink from some another page on the website.... hyperlink is also a vote to the linking page
