I've been outsourcing profile links on high PR domains (PR6+), but so far I've only been adding anchored links to the profiles, and nothing else. We all know that Google gives more weight to links that are embedded in text, but I am wondering how much text is necessary to make a difference? For example, do you think adding 10 words before and 10 words after my link would make a considerable difference? I've had great success with posting unique articles to web 2.0 sites, but those articles are ~ 300 words and it obviously wouldn't be cost effective to pay to have a couple hundred words written for each profile link. Basically, I'm trying to decide if it would be worth spending extra cash to have a couple unique sentences written around my links, or if I would need more text to make it worth it. Has anyone else experimented with this?
