My lady has a blog, fashion & beauty related. She had it for about 3 years and it does get some traffic, but nothing really major (I think it's like 2000 visitors per month ). Content is excellent though, she has degree in English literature and journalism. I have examined her blog and the only thing which is missing are backlinks(I think there are only 8 or 10 of those at the moment). Mostly she has written articles or product reviews for pr/marketing departments of major brands.
My question is would it be sensible to take some of these articles and post them on article submission sites in order to get backlinks ? Which ones would you recommend?
Do we have to remove these articles from a blog after we post it on an article submission website?
