Im doing link building using article submission sites to get more back links to improve my search engine rankings.. im think if i should build around 50 incoming links from ezinearticles.com or if i should build around 50 links from 50 different article submission sites.. which will be more effective way to do link building for SEO ?
If you can obtain 50 links from ezinearticles then you should try it first if not then 50 links from 50 sites.
links from different sites are generaly better, however if we're talking Ezine articles, then I'd do 50 links from there too. Because they will generate you traffic.
I really agree with this answer because get 50 links from different article sites better that 50 links from only one site. I am also getting 40 links from 40 different articles sites.
50 links from 50 different websites is anytime better. But then you must ensure that the websites from where you are getting links are good websites which gets cached in Google regularly. Otherwise I would prefer getting 50 links from 25 top websites i.e. 2 links from each website.
