AdWords users may see an increase in the number of impressions though as reported by Google. When a user types a query and pauses for three seconds, it counts as an impression. Now, when the query is completed and the results get refreshed, it will count as another impression if your ad gets displayed. This could mean a reduction in the clickthrough rates.
The job of SEO experts was made difficult since the time search started getting more and more personalized. Two people could be searching on the same term, yet see different results based on their geographical locations, especially if they are signed into their Google Account.

In such a case, there is only a certain amount of search engine optimization that you can depend on because the results are not within your control. However, to say that the search engine optimization is becoming less relevant would be incorrect. The days of keyword stuffing and AdSense ads are definitely over – SEO techniques are getting more sophisticated and businesses actually want to provide their users with information that will make them keep coming back.

This is all fine, untill your data grows in size to petabyte scale, then old way simply isn’t feasible. Tagging, sorting, and categorizing, would take an emmence amount of time. A single computer, no matter how large, just can’t crunch that many numbers at once.

Google Data Structure

Google use a very different approach, when sifting and ordering the world wide web. Thier solution for working with colossal data sets, is an approach called MapReduce.

It works like this:

1. Collect

MapReduce does not depend on traditional databases, where information is collected then categorized. We’ll just gather up the full text of every book Google has scanned.

2. Map

You then write a function to map the data: “Count every use of every word in Google Books.” The request then splits among all the computers within your army, each is assigned a chunk of data to work with.

3. Save

Each PC doing a map, writes the results to its local hard drive, cutting down on data transfer time. Then the computers that have been assigned a “reduce” function grab the lists from the mappers.

4. Reduce

Then the Reduce computers correlate the lists of words. Now you would know the frequency of a particular word that is used, and in which books.

5. Solve

The system finally creates a data set about your data! In my example, the final list of words is stored as separate sets, so it can be quickly referenced or queried. So then you don’t have to plow through unrelated data to get your answer.

Search engines can penalize a sites ranking if it looks as though content has been taken from another site. However, these sites do sit in index and even rank very well. How can this be? Does it mean there are no filters?

Filters exist, but they are in a primitive form

Search Engine’s need lots of resources to check the entire internet. Therefore, engines use simple forms to uncover duplicate content.

How?

The most common pattern is links. In general engines check between two linked sites for duplicate pages/content. If they exist, then engines try to get rid of the duplicate – usually the one who links to the source site.

How does this work?

If website B (healthy news) republished an article from site A (health research institute) and puts a link from B to A for reference, search engines understands that site A is the original source and the site B has copied it. Site B is seen as dupe content website.

How do search engines penalize?

One or two articles like this won’t harm your site much for example, if website B has lots of original content. However, if duplicate content fills a significant number of pages, websites can be penalized by being moved down in the search result pages, moved to supplemental index or even unlisted from search index.

Test Conducted

Website X has 5 pages of original content and ranked #1 for very uncommon search term. This website has 100+ links pointing to it and Google PageRank of PR4. After few weeks 30 pages of content from another site that required a link back to it were added. In results, after Google indexed the website, it went from #1 position down to about #67 – #100. The test was continued by adding even more links – but even an extra 100 links
(now site has over 200 links) didn’t help to move it back of even above these #67 – #100 low positions.

After 3 months – duplicate pages were removed.  After search engines updated the website – it slowly moved back to position #2.

What does it mean to you?

The idea is simple – don’t link to websites that have the same content as yours – especially if it is in huge amounts compared to total number of pages.

What you should do?

You may not link to websites with duplicate content but your website may have lots of popular articles like from MoreNiche Content Connection, it is useful to follow few rules of thumb which are based on the fact that engines evaluates the whole page’s code not just the article itself.

To put it simply  – engines see all page as code, that probably includes site specific menu, HTML tags, layouts, title, descriptions etc. so it mix it up and articles aren’t considered  as duplicate since it is part of some bigger code. That’s the secret.

Some useful tips for Content Connection users

To ensure even more security from search engines it is recommended to use one or more of these tips:

1) Use articles on pages that have a solid size menu
2) Try to have a unique intro and closing for used articles, change titles
3) Use synonyms to replace words
4) Insert comments in the middle of an article or links to detailed info
5) Insert contextual short product reviews (1 picture plus one paragraph and link to full review will be just fine)
6) Split longer articles into 2 pages or more as long there stays 150 – 200 words on each page
7) Rewrite articles into your own words
Combine two or more articles into one
9) If there are bullet points – mix their order if possible
10)Think outside the box…

Last tip

Don’t try to host a DMOZ directory or part of it for making more pages on your website. Google can easily ban you for that and remove your entire site as happened to a website about coffee that hosted 10000 pages from DMOZ to drive extra 500 visitors a day.  Sad but a fact. Duplicate content is evil. Be aware.
