Search engine rankings on certain keywords for websites can fluctuate all the time, which comes down to the way the search engines are ranking your website based how the website has been optimized. From one week to the next, the major search engines can make the website jump from page to page, especially if you have made a lot of changes onto the website. This can come as a bit of a mystery to many as it is difficult to predict when these shuffles in the search rankings will happen. With Google optimization there are several filters that they use in order to rank a website as well as Google penalties that are issued if the website is not appearing to follow their guidelines.

Below are just a few of the filters that Google use on a regular basis. Google have not confirmed these filters via any press releases but these are assumptions and theories created by SEO specialists.

Google -30

The Google -30 filter looks through the website and checks for any SEO spam techniques that the website has tried to implement. Tactics such as keyword stuffing in the meta description and in the content will bring penalties and as a result will drop the websites ranking by 30 places.

Google Bombing

The Google Bombing filter is applied to sites that seem to gain a large amount of inbound links with the same anchor text. This for Google is extremely unnatural for inbound linking to all have the exact same anchor text.

Google Sandbox

This Sandbox filter is mainly used for brand new websites that are seen to be applied to domain names that have been around for a long period of time. With many domains not lasting longer than a year, Google introduced a filter to make sure that a new website doesn’t receive decent rankings for competitive keyword terms. These sites can still receive non-competitive keyword terms though.

Google Duplicate Content Filter

As the title of the filter suggests, the duplicate content filter is applied to websites who take credit for content that has already been created and indexed on other websites. If this is found to be the case then this page will not be ranked highly and Page Rank can be devalued as a result of this duplicate content.

Google Domain Name Age Filter

The domain age filter works closely with other filters with the idea being that the older websites and domain names are much more likely to have better ranking results for keyword terms than newer websites. As the site gets older, the more results will appear for more worthwhile keyword rankings.

Google Links.html Filter

If you are using reciprocal links to gain more inbound links and are also holding these reciprocal links in one file on the website which so happens to be called links.html then Google will spot this. Google can filter out any pages containing reciprocal links especially when they are hidden away not to be seen by search engines. Search engines don’t promote reciprocal linking anymore although usually it doesn’t harm your website, but it brings no benefits.

Google Over Optimization Filter

Over optimization, such as keyword stuffing, high keyword density or high keyword proximity can be seen as too much SEO. Google will penalize your website for over optimization as it prefers natural websites that are totally user friendly, it doesn’t like to see you trying hard for SEO.

Google Too Many Links Filter

If you are really pushing your link building campaign you may end up bringing in too many links all at once into the website which can cause your website to be banned from Google. Factors including the timeframe of links obtained and where the links are from are included in the code for this Google filter.

Google Link Farming Filter

Link farms contain a huge amount on unrelated links and are completely disapproved of by Google. Linking to bad neighborhoods can lead to drops in your SEO rankings and even cause your website to be banned from rankings.

Google Trust Rank Filter

Google loves to rank websites and much like the PageRank rating, Google has a trust rating for all of the websites on the internet. This trust can be built up by one-way inbound links, domain age, website age, regular content updates and so on, all of the factors that help to build your website up as an authority. If your site has a low trust rank then you are likely to have low results in the natural listings.

CO-citation Linking Filter: This popular filter by Google watches your inbound link structure. If your link is on a site who’s outbound links are related to casino’s and porn sites and your automotive site is an outbound link on this site then google will think your site is related to porn and casinos. Poorly constructed co-citation will damage your ranking and make it hard for you to rank well for the terms you are targeting.
