The Truth About Content Filtering Online
If you are a search engine operator, are starting your own online company
, or if you are just interested in how the internet works, content filtering is something you may want to dedicate some time to learning about. Duplicate content and how it is handled by filters is something of particular significance and interest lately, as it has everything to do with making an internet company more successful.Search engine spam is any deceitful attempts to deliberately trick the search engine into returning inappropriate, redundant, or poor-quality search results. Many times this behavior is seen in pages that are exact replicas of other pages which are created to receive better results in the search engine.
Many people assume that creating multiple or similar copies of the same page will either increase their chances of getting listed in search engines or help them get multiple listings, due to the presence of more keywords. In order to make a search more relevant to a user, search engines use a filter that removes the duplicate pages from the search results, and the spam along with it.
Unfortunately, good, hardworking webmasters have fallen prey to the filters imposed by the search engines that remove duplicate work. It is those webmasters who unknowingly spam the search engines, when there are some things they can do to avoid being filtered out.
In order for you to truly understand the concepts you can implement to avoid the duplicate content filter, you need to know how this filter works. First, we must understand that the term "duplicate content penalty" is actually a misnomer.
When we refer to penalties in search engine rankings, we are actually talking about points that are deducted from a page in order to come to an overall relevancy score. But in reality, duplicate content pages are not penalized.
Rather they are simply filtered, the way you would use a sieve to remove unwanted particles. Sometimes, "good particles" are accidentally filtered out.
Knowing the difference between the filter and the penalty, you can now understand how a search engine determines what duplicate writing is. There are basically four types of duplicate work that are filtered out.
The first is websites with identical pages. These pages are considered duplicate, as well as websites that are identical to another website on the Internet are also considered to be spam.
Affiliate sites with the same look and feel which contain identical work, for example, are especially vulnerable to a duplicate content filter. Another example would be a website with doorway pages.
Many times, these doorways are skewed versions of landing pages. However, these landing pages are identical to other landing pages.
Next, is what is called scraped content. Scraped content is taking writing from a web site and repackaging it to make it look different, but in essence it is nothing more than a duplicate page.
With the popularity of blogs on the internet and the syndication of those blogs, scraping is becoming more of a problem for search engines. Next is e-commerce product descriptions.
Many eCommerce sites out there use the manufacturer's descriptions for the products, which hundreds or thousands of other eCommerce stores in the same competitive markets are using too. This duplicate content, while harder to spot, is still considered spam.
Last, we must look at the distribution of articles. If you publish an article, and it gets copied and put all over the Internet, this is not necessarily a good thing as you might originally assume.
This type of duplicate information can be tricky, because even though Yahoo and MSN determine the source of the original article and deems it most relevant in search results, other search engines like Google may not, according to some experts. So, how does a search engine's filter work?
Essentially, when a search engine robot crawls a website, it reads the pages, and stores the information in its database. Then, it compares its findings to other information it has in its database.
Depending upon a few factors, such as the overall relevancy score of a website, it then determines which are duplicate content, and then filters out the pages or the websites that qualify as spam. Unfortunately, if your pages are not spam, but have enough similar content, they may still be regarded as spam.
The duplicate content filter is sometimes hard on sites that don't intend to spam the search engines. But it is ultimately up to you to help the search engines determine that your site is as unique as possible.
This is why it is important to keep your information and how you present it fresh, and original. By doing so, you can avoid the annoyance of getting rejected by internet filtering.
