The most successful photographers often times are not the best, just the most well-known. That Verizon guy “Can you hear me know” is well-known because he is EVERYWHERE, from commercials to billboards. We like to get well-known everywhere by commenting on other blogs and in community forums.
Blog comments and forums often have a URL field. Those URLs are for showing who you are and do not add link value for search engines.
When you add value to a conversation with a comment, those who want to engage will click through your profile link. Sending them to Facebook offers an easy way to connect (especially when you tell them to – a Call to Action).
Takeaway: Link to your Facebook URL when you comment on blogs and forums in order to connect with those who took an interest in you.
