Hi, How much do you think guest article marketing influences SEO overall? I've been guest article-spreading during the past 1-2 weeks for a new site and I have like 4-5 partner sites putting up periodically articles for the same site. I could have 40-50 articles in 2-3 months, but spread across 4-5 sites only. Is that good? Bad? Too many per site? By the way, they are weak to medium sites, none of my partners has much strength in Google and their PR is usually 2-3 only. But these were the best I've found so far... Looking for more sites to place articles, how much do you think this will influence my SEO? I'm relying mostly on article posting now. I was wondering whether it's effective in 2013 as well.
