Hi, I'm a noob to this forum but not to internet marketing. However one thing I've never fully understood (or ever made use of) is social bookmarking. I'm hoping someone here can help explain this to me as it is related to getting a competitive advantage when it comes to SERPs. Ok I know what social bookmarking is: you post links to your site at places like digg and you get a) backlinks and b) possibly more traffic. Awesome. Here's what I'm wondering about: I see posts that are like 400 SOCIAL BOOKMARKING SITES! Or like HUGE 1,000 SOCIAL BOOKMARKING SITES!!! Ok, so you have a big list of sites. Now what? 1) I seriously doubt that there are people with legit social bookmarking accounts who sit around all day going "Gee, I wonder what cool new links were posted on [insert social bookmarking site] today!" So I can imagine any increase in traffic is minimal at best. 2) People get all these lists of social bookmarking sites and EVERY SINGLE TIME, without exception, the next question in the thread is "what software do I use to automate this?" Throughout all of these, I've seen a few mentioned (such as BMD), but EVERY SINGLE PERSON says it sucks, it can't break CAPTCHAs, the proxies are banned, or only a very small percentage of the links actually go through. So that makes me wonder, what is the purpose of these giant lists of bookmarking sites if you have to do them all manually? That would take FOREVER, for something that probably won't even get indexed and if so will only pass a tiny bit of link juice onto your site. It doesn't seem like a time-efficient strategy to bother manually creating social bookmarking sites. 3) Forum spam and comment spam are both at all time highs. In fact, Google will soon be ignoring forum spam (there's an article posted about it somewhere... basically Goog knows that forum spam is used by internet marketers and pretty soon it's not going to count when factoring your SERPs and may possibly result in a penalty) and same thing with comment spam. "OH WOW YOUR ARTICLE WAS SO INTERESTING PLEASE VISIT MY SITE FOR [insert link]." Surely Google must know that a large percentage of social bookmark sites are just BS spam from IMers, so how viable of a strategy is it, really? It just seems to me like you'd sit around all day manually creating accounts and submitting links to your website (since all of the tools that claim to do it automatically don't work) and then maybe a small percentage of those actually get indexed and give you a little boost in the SERPs. And how many HOURS did you spend doing that? What am I missing here? Thanks guys.
