One thing about Search Engine Optimisation is that you cannot afford to rest on your laurels. Take my 'Melayu Boleh' project for example - which started out as a competition initiated by Mohd. Suhaimy but later became a personal campaign to dislodge porn blogs from Google search results for the above search terms.
I eventually won the challenge on February 02, 2007. That was a great effort and in fact, the first results page didn't have any links to porn sits for a while.
On January 12, 2007, my post was #4 in Google search results for melayu boleh. It even went up to #2 and I think that was the highest it ever went up to.
It later dropped and I had to work hard to bring it back to #8 position in Google - 18 Aug 2008.
However, I stopped bothering after a while and now my post is nowhere to be found on Google results.
