Profile links are one of the most discussed topics on SEO community. So, back on Mart 2010, I decided to make my own separate research about the effectiveness and weight of profile links.
I have tested 3 of my static niche sites and used only profile links from forums and other communities. At the same time I worked on SEO of my other same type static niche sites for comparison.
I have really been amazed with the results. I discovered that profile links are one of the 3 most effective and fast backlinks today. The sites I tested got some significant jumps on Google within 7-10 days for medium competitive keywords. This is very important. Not all links can do this job. I have got the same results with only 2 other strategies before in my SEO practice, so it surprised me a lot.
Best of all, the results are effective for long term. Mainly the result changes like this: 7-10 days after getting profile links, you see sudden jumps in SERPs, after few days SERPs decrease a bit and then after some days SERPs go higher.
If anyone has other experience or want to say about the profile links, then feel free to post your comment below.
I am going to do another research for other sites, too. Hope it is helpful for you.
Feel free to post opinions about your experience with profile links.
