People who use Google to search for information benefit from specific filters it uses to provide better search results. When someone is looking for information on a particular subject, they don't want to have the same article coming up time and time again because the it has been posted on a number of different article directories. Google's duplicate content control check is a means of making sure that duplicate content is kept to a minimum.

The following is a list of several common filters Google uses and how to bypass them, therefore bypassing most of Google's Duplicate Content Check.

Filter #1: Google Sandbox

The purpose of this filter is to ensure that, for high search engine queries, new websites do not receive high rankings. Make it a habit of linking your web site to more established and popular ones as a means of bypassing the Sandbox filter.

Filter #2: Google-30

If you are using your web site to spam illegally, then Google will applies this filter. The filter will push your web site down by 30 ranks when it discovers illegal spamming tactics. Make use of black-hat search engine optimization strategies on your web site in order to bypass this filter.

Filter #3: Google Bombing

Google will look with suspicion at your web site if it discovers that your site has a substantial number of external links that have similar content inside of <a> tags. This Google filter is applied in matters that involve paid link promotions. Get rid of these links by changing them into other kinds of linked text to bypass this filter. Then make an application to be indexed again. The only way to bypass this filter is by removing the links; it is quite hard to bypass.

Filter #4 CO-Citation Linking Filter

Your web site's topic is defined by the topics of web sites that link to it. When Google sees these links, it determines what your web site is about. Google will identify your web site's topic as medical in nature if, for example, you link to a web site that links to several medical web sites.

Taking care as you link to other web sites is the method of bypassing this filter. Make sure the sites you link to have content that is related to your site's content.
You also need to pay attention to how many pages you are adding to your web site. You don't want to have too many, and it is a good idea to stop adding pages and come back later if you find you are creating too many.
Illustrating additional uses of HTML tags is another function of this filter. It is important not to over-optimize your site's content which is how you bypass this filter.

Filter #5: Google Domain Name Age Filter

The Sandbox and Trust Rank filters are close cousins of the Google Domain name Age filter. Bypassing this filter requires that you make use of quality links.

Filter #6: Page Load Time Filter

Google will penalize your site if it takes too long for pages to load, so you want to make sure that your site's pages load quickly. Bypassing this filter is simply a matter of ensuring fast page loads on your web site.
