Which database does Facebook & Google use ?

Facebook has moved to a NoSQL database named HBase. Google uses their own system called BigTable. What is NoSQL ? NoSQL is a term used to designate databases which differ from classic relational databases. NoSQL database management systems are useful when working with a huge quantity of data when the data's nature does not require a relational model. The data can be structured, but NoSQL is used when what really matters is the ability to store and retrieve great quantities of data, not the relationships between the elements.

How To Get Your Adsense Account Approved And Increase Traffic To Your Site !

The first question that should strike your mind should be:

 "Why Does Your Request Gets Disapproved?"

You may already know that AdSense works by crawling your web pages for content, then delivering ads based on that content. This means :

1. That if your content is limited, there crawler may have difficulty identifying the information on the page. 

2. The content is enough but still all cluttered due to improper labeling,and again crawler is having difficulty in identifying content type. 

As a result, your request for the approval may not be considered and disapproved or if approved you may see ads that are not directly relevant to your page.

Here's a solution : Ensure that your pages are full of compelling content. The more targeted, text-based information you provide to there crawler, the easier it will be for there system to determine what your pages are about, and the greater the chances of the approval will be. 

I think everyone of you out there has some image like this at the back of your minds after the approval from the AdSense........

Well lets work on getting the most out of it alongside........

Here's a simple equation that spells it out:
1. A content-rich page = Highly-targeted ads  
2.Highly-targeted ads + Interested users = Healthy clickthrough & conversion rates  
3.Healthy clickthrough & conversion rates = Success! 

 

 

 

How to tell the CRAWLER what your pages and content are all about? 

You can use page section targeting to focus there crawler on certain sections of your page that may be more content-rich than others.

The HTML tags to emphasize a page section take the following format:


<!-- google_ad_section_start -->

<!-- google_ad_section_end -->

You can also designate sections you'd like to have ignored by adding a (weight=ignore) to the starting tag:


<!-- google_ad_section_start(weight=ignore) -->

With these tags added to your HTML code, your final code may look like the following:


<html><head><title>Section targeting</title></head>
<body>
<!-- google_ad_section_start -->

This is the text of your webpage. Most of your content resides here:


<!-- google_ad_section_end -->
</body>


 ...All The Best...
