I've used social bookmarking in my arsenal of link acquisition for years with success.
My advice was to knock out a 'supplemental' or 'indented' secondary listing that your competition has when they search for your keyword - especially if you are in the top 20. One extra position equates into sometimes double the traffic. In the top 10 in this (poker) market one position could mean tens of thousands.
Over time I have gotten more flack from people that never believed it could work - over and over and over again.
As was the case recently.
So i decided when I saw the criticism, I was going to go out and immediately start yet another test to prove how strong a technique it was, but I never expected this...
I performed this search "poker" in the default Google (no regional or language filters) and since I am still in Amsterdam it searched from my Netherlands based IP at my hotel. Here are the results;
Notice PokerListings.nl's position - #9, and notice the two listings above it; nl.pokernews.com - with 2 listings. Notice what the URL and search term is.
I ran this at 10 AM GMT on the 4th, just after being doubted yet again
And this morning at 6AM, less than 24 hrs, here are the results;
Not only has the indentation been removed, earning one better position for the target site, but the rank was improved placing them ABOVE them as well.
I'd like to think that I don't need to prove myself each time I get questioned, but I guess we need to question the claims made by many SEO's since so many of them are another author's repurposed statements.
I test everything because you never know what your getting - especially from the likes of Google.
If anyone else gives this a go please publish your results. We don't need to see screenshots and URL's, although you could use a random one like I did.
One more thing...the last time I ran this strategy the ranking increase on Google lasted around 30 days and Yahoo and MSN lasted 45 days.
Give it a go!! (but definitely DO NOT abuse this. The SBM sites will ban you and it may run a red flag at Google if abused)
