I'm building my links using link:www.xyz.com on GOOGLE (where www.xyz.com is competitor's url or website of similar niche). Now i have built few links from such sites. But only one link is indexed in google. I have already used pingomatic and search engine pingler tools but no change. I have noticed that google is also indexing facebook page, twitter account and linkedIn page as backlinks then why my pages are not indexed as google backlinks.
What else i can do build GOOGLE BACKLINKS? OR I must try some other method to generate GOOGLE Backlinks. Now thinking about getting reciprocal links... Will that harm my site due to penguin updates?
