Google’s Minus-30 Filter

Webmasters in online forums are reporting a new Google filter that Google uses to downrank web sites in its result pages. Has this filter been applied to your web site? How can you avoid Google applying that filter to your site?

What is Google’s Minus-30 filter?

The Minus-30 filter is a penalty that Google applies to web sites that use spammy SEO techniques. If Google applies the penalty to a web site, the rankings of that site are dropped by 30 positions. Many webmasters in online forums reported that they had top rankings on Google and now they can’t get beyond position 31 at the top of page 4 in Google. Some webmasters even report #31 rankings for all of their keywords on Google.

Why does Google apply the Minus-30 filter to some web sites?

Google seems to apply the -30 filter to web sites that use certain spamming techniques. The following techniques appear trigger the Minus-30 filter on Google:

  • Guestbook spamming: If you try to get inbound links by spamming guestbooks and blogs with links to your web site, then Google might apply the filter to your web site.
  • JavaScript redirects: JavaScript redirections might be misinterpreted as a spamming attempt. Better use 301 htaccess redirect if you must redirect URLs on your pages.
  • Doorway Pages: Google doesn’t like doorway pages. If you must use special landing pages for PPC ads and other ads, make sure that these pages can’t be spidered by Google and other search engines or they may be interpreted as an attempt to spam the search engines. You can use a robots.txt file to mark those pages as not to be spidered by the search engines.

What can you do if Google applies the Minus-30 filter to your site?

First of all, remove any search engine spam elements from your web site. If you use JavaScript redirects or doorway pages, remove them from your site.

The Minus-30 filter seems to be an automated filter. If you remove the spam factors from your site then you may get your rankings back after some time. You can also send a reinclusion request to Google. If nothing helps, then the only way to get reincluded in Google may be to get a new domain name. (!)

Google doesn’t like spammers. If you want lasting results then you need to employ only ethical search engine optimization methods. Like we do at Rank Magic.
