SEO in Thailand is harder since G penalty.
tagged algorithm, banned, google and thailand
Recent changes in Thai algorithm , and banned in many major seo players in Thailand cause more difficulty for search engine marketer ,TH said.
Thailand is quite a niche market especially if you target for Thai language ,many SEOs can get top SERPs within few months due to smaller and lesser sites , and quite weak language filter . You can find many weird practices , hidden text , doorway pages , keyword stuffed , keyword spammed , or every possible black-hat techniques , surprisingly on Thailand top 20 sites !
Google has concerned also the poor quality of search in Thai language , after complaint from many companies . The last changed in text filtering mechanism started on 10th Jan 2008 has major effect to many black-hat sites , and yet to normal sites who also use -search pages with tagged ( or record queries). The impact still need to be evaluated in the long term , but right now , quality of search is much improved. We are hoping for initiation of genuine Thai Adsense Service after fine tuning of all filters.
