Casual Articles - Duplicate Content: What You Ought to Know About
In the old days, stuffing your web pages full of the same keyword was a guaranteed way to boost your web site to the top of the search engines. However, in the Web 2.0 world, search engines are smarter, and the old tricks won’t get you anywhere.If you read many blogs or forums, you have probably seen plenty of debates about keyword density.Many people believe that Google likes a keyword density of two to three percent, while Yahoo and MSN prefer six to eight percent (some even go as high as twelve).With all the disagreement on the subject, how are you supposed to decide what density to use?At SoftwareProjects, we believe that when you’re writing content, keyword density shoul
How Do Duplicate Content Filters Work?
There are several algorithms in data mining aiming to detect similar text passages. The one claimed to be used by search engines is w-shingling. Each document has a unique fingerprint or shinglings - the contiguous subsequences of tokens (blocks of text). The ratio of magnitude of union and intersection of two documents' shinglings can be used to determine their resemblance. Another algorithm that can be used for duplicates detection is Levenshtein's distance

Trainers, please picture this... You are presenting in a new location to a new group. You are prepared for a one day workshop. Your materials are ready and you are “on”. Things seem to be going well. You are building a nice rapport with the class and the pace of the training is right on schedule. About two hours into your day one participant starts to demonstrate disruptive behavior. This individual begins talking to the person beside him during the lecture. A few minutes later, during an activity this gentleman is doing everything in his power to take people’s attention away from the subject at hand. As the calm cool trainer you are, you try to work with him to no avail, and his behavior is really starting to affect the others in the workshop. You’ve go
Penalties for having duplicate content can be really harmful. This is not just a downgrade in rankings but a move to supplementary results which are hardly visible to the most of the web users. Normally it is expected that Google would select one URL over another to display in SERPs, while duplicates could be found in supplemental results. Unfortunately this is not always so. In the thread "Duplicate content observation" in the WebmasterWorld.com forum you can read about a case when an original high quality and authoritative page was removed from Google's index together with its duplicates. Considering that this can happen even to the most honest webmaster, one can imagine the amount of attention this issue gets on any SEO forum.
Types of Duplicate Content
Duplicate content has a wider definition than the 'copy-paste' plagiarism; it is not just content scrapped from a competitor's site, a SERP or a RSS feed. Apart from this there are few more aspects that are generally referred to as duplicate content.
Circular Navigation
Jake Baille from TrueLocal vaguely defines circular navigation as having multiple paths across website. This can be understood as the same content being accessible via different URLs. An example of the circular navigation could be an article that is retrieved by links like
- example.site/articles/1/ ,
- mysite.site/article1/
- mysite.site/articles.php?id=1
Another legitimate use of multiple URLs is forum threads. Each thread can be accessible by a link like myforum.site/index.php/topic.1201.html , and each message within the tread has a URL like myforum.site/index.php/topic.1201.msg.01.html . In the eyes of a search engine all the links lead to different pages with identical content. Solution? Think of a consistent way of linking, or apply robot.txt exclusion rules.
This can also be the case when other people link to you using differently looking URLs. Since these external links are out of your control, you should create a 301 redirect to the canonical URL you choose to be displayed.
Printer-Friendly Versions
Making a printer friendly version is a common practice and it adds value to the visitors. But printer-friendly version is also a prominent example of duplicate content! Fortunately a simple solution like adding a 'noindex' meta tag to your print pages solves the issue.
Product-Only Pages
Product pages looking similar are common among online stores. Typically they are created using a single template. Often two different product pages share a description that varies in just few words or numbers, which causes them to be filtered out as duplicate content. This issue has no easy solution. Either you rewrite robot.txt to allow only one product description to be crawled and lose SE traffic to the rest of them, or you roll up your sleeves and add something different to each product page, like testimonials, which is time consuming or nearly impossible depending on the number of product types in your stock.

At one hundred sheets (or one thousand cards), however, offset printing will cost about $7, while the copy store's rate goes up to $10. Add to that the fact that the offset plate only needs to be made once, which means that if you print a thousand cards for $7 in June, you can get a thousand more for $2 in September--a total cost of $9. The chain copy store will charge $20. (Again, less machine cutting.) That leaves much more room in your budget for the more expensive finishing options that can make a card great.Of course, the simplest method of reducing costs is to reduce the number of features on your card. It's possible to do this without compromising your original intentions, especially if your design doesn't actually depend on advanced printing fea

The current era can rightly be termed as the era of innovation. The technology has improved a lot during this era. The use of internet has increased a lot. Never before in the past was the use of internet so common. Today the bulk of the trade and businesses have their own online interfaces for their prospective customers. The world of trade and commerce has changed a lot. Not only that the internet has changed the face of the world of trade, it has also affected us in many other ways. Internet is also the most important source of information exchange today. Keeping all these in view, we can use forums on the websites to our advantage. Forums are those web pages on a web site which are dedicated to discuss a certain problem or issue. The opinions of people who are

You could be generating 50% to 100% more sales with your marketing. How? By working with basic human nature to convert more of your prospects to customers.Each week 100 or 1000 people visit your web site or read your small business marketing materials but only a handful of those are contacting you. You can double the number of people who buy your products and services and double your profits.The biggest mistake made by small business owners is that they treat marketing as if it didn't need to follow basic rules of human nature. It's like trying to force feed broccoli to someone who hates vegetables or trying to get a vegetarian to eat roast beef. Similarly, it just doesn't make sense to try and force your prospects to do something they don't want to d

One of the most popular questions asked in online business forums or even by my customers and subscribers is this :“How the hell can I increase my sales?”or“I’ve got tons of visitors but nobody seems to be buying anything? What gives?”FISHNETS WITH HOLES? ANYONE?Getting traffic is not the be all and end all of a successful online business. It requires skills, specific online marketing strategies designed for your site and a robust customer service strategy.So what if you have thousands of visitors per day! That does’nt amount to success, unless you close at least 5 to 10% of those visitors.You see, when you get a lot of traffic from your advertising and marketing activities and nobody there to guide them, is like ha

It is naturally to expect from a duplicate content filter to be able to discover the origin and rank it higher. The simplest way to detect the origin would be comparing the date of indexing implying that the original source is uploaded and crawled earlier than its copies. But with the advent of the RSS feeds the new content can be distributed instantaneously and this approach is no longer valid.
Concerning the origin's right to be ranked higher - this is not always implemented. In this article you can read about an experiment of an article distribution. An article was syndicated twice scoring as many as 19000 copies. After some time Google, Yahoo and MSN have purged their indices leaving just few of the duplicates. MSN's filter managed not only to discover the origin but also put it to the top of the search results. Yahoo has also discovered the origin, but in the results page to the title of the article, the origin's position fluctuated obviously responding to the way Yahoo counts relevancy and authority.
To the tester's amusement Google's refined index did not include the original at all! Evidently Google featured only those pages with copies of the same article which it considered relevant and authoritative with no regard to the original source of the content! I've already mentioned a thread where a similar problem is discussed. The both stories took place in 2005 and early 2006 and so far I found no evidence that this issue is resolved.
