we have some articles, unique ones.. Of course, we have written them using lots of keywords for our market. Shall we link all this keywords to the sale pages (pages that we wish top SERPS in Google) ? Or shall we keep keyword as a normal text, with no links ? Is using <b> a good strategy for such keywords ? And also, in some cases, the article have 5-6 repetitions for each keyword.. Shall every one have a link, a <b>... ?
You should use the Author Bio section really. Many Article repositories don't allow more than 2 links per article. Simply use the targeted phrase in the Author Bio and link the texts to the corresponding targeted pages
ahh Ok... and your thinking of using an internal linking structure from them? Meaning terms in the article linked to other pages in the site? Is this correct?
Well it will have some (limited effect) to be certain. Not much though. A good internal linking structure is always important these days for indexation Outside of that linking more internally to given target pages will also ensure the level of importance given to it. Will it help with rankings? No, not really.
