Google Penalties And Filters

Some SEO's do not agree that Google uses some special filters to rank a site but many SEO's believe in these filters and also give evidence on the existence of these filters.

The reason behind these filters is still unclear, but most probably they are applied to stop spammy sites and the sites using unethical SEO to get higher positions in Google search engine. These filters are either built in Google Algo or applied time to time individually in case of Google Bomb (simply awesome biggrin )

Google & SEO

These filters surely do exist. I`we gone through few of those mentioned in post.
Google Sand Box Filter slapped my new site when only going for the right keywords to often. Bam ... site was doomed in engine for 5 months. 7 months old site or domain that was. But that could also go as Over Optimization.
Google Domain Age Filter, i dunno bout that, i`we experienced that sites in high competitive niche did well, although dmoz editors go for domain age among other things.
But the point is, yep, those filters sure do exist as many of us got slapped by it one way or the other.
