If I have a site with like 20 pages and each page is on a long tail keyword that is based on a 2 word niche. For example let say the niche word is "home widget." Then some of the longtail keywords that I'm targeting is "home widget keyword1, home widget keyword2, home widget keyword3, keyword4 home widget, etc. The long tail is either another word in front of "home widget" or after it. So when I'm building links it is better to like use 20 different anchor texts or can I combine some of the longtail keywords? What I mean is can I rather do "keyword1 home widget keyword2" or "keyword3 home keyword4 widget keyword5", etc. for the anchor text? Let's say that those exact combination of words have no search volume (from Google Adwords Tool), but a combination of 3 of those words in that 4 or 5 long tail anchor text does have search volume, will be I be able to move up the SERP's for all the combination of 3 word keywords or just only for that exact 4-5 keyword? So when someone searches for a 3 word keyword will I have built juice with those 4-6 long tail keyword anchor texts? What I mean is do you guys check whether your long tail anchor text has any seach volume/ad competition or that does not matter? I like to do it this b/c I want to move up the each of the 20 keywords. Wouldn't this be a better SEO technique than just varying that main keyword by either inserting like "info", "guide", "all" etc. to it?
