Comment spam. We all do it, some better than others. I want to pick your brains on the following issue: How much can/does google infer about your link from the surrounding text? For example, I have often thought it would be easy for Google to identify some of my links as comment spam and devalue them. However, it does not do this. E.g. it would be easy for Google to look for "nice post" and other thankyou 1-line posts with a link, or devalue all links which are preceded by "posted by" etc. There are so many ways. What I do at the moment: I prepare a paragraph of text related to my own niche, and insert no more than 2 of my links into it. The paragraph is altered every x number of postings. Note: I deal almost exclusively with unmoderated sites. So many spam comments out there are endless chains of hundreds of links. How can Google fail to notice these as spam? Mainly what I want to know is: What's your comment spam strategy and why?
