How Web search Engine and Page Ranks are linked
World Wide Web Worm (wwww) is claimed to be the first search engine and was released after March,1994. It had 300,000 multimedia objects and was available for searching keywords through WWW.
Today’s world the most important search engine Google came into existence in Jan,1996. This was developed during the research project by Larry Page and Sergey Brin while they were doing the PhD. The term Page ranks were named after Larry Page and which is widely used now.
Let’s see the challenges that Google had to scale up with the increase in data. Retrieving data has been the challenges and that was done efficiently with crawling technology and along with efficiently used storage space and proper indexing process. Google was designed well to optimize the data structure so that results in favorable scaling properties for centralized systems.
In Google’s word,
The citation (link) graph of the web is an important resource that has largely gone unused in existing web search engines. We have created maps containing as many as 518 million of these hyperlinks, a significant sample of the total. These maps allow rapid calculation of a web page’s “PageRank”, an objective measure of its citation importance that corresponds well with people’s subjective idea of importance. Because of this correspondence, PageRank is an excellent way to prioritize the results of web keyword searches. For most popular subjects, a simple text matching search that is restricted to web page titles performs admirably when PageRank prioritizes the results (demo available at google.stanford.edu). For the type of full text searches in the main Google system, PageRank also helps a great deal.
Page Rank calculation is done through an iterative algorithm. But we are not interested here about the algorithm rather how it affects and what good practices can be done for better search behavior. So Page rank is nothing but a human behavior which can be explained as the random surfer visits web pages randomly and never hitting the back button. He randomly picks up links and keeps visiting the pages until is bored and then visit to a different page. The probability of visiting a page is its PageRank. So basically the page which is linked by number of other pages will have the higher PageRank. Similarly a page which is linked from (may be a single link) from a site like Yahoo or which has higher ranking status will also result a higher PageRank.
As the content is getting added and modified on the Web , the search Index is also getting updated every moment. So as in the ranking algorithm. If the page is connected well with high number of linking, the percentage of the page will be getting added to the Google’s database while the next crawl happens. Because of that the indexing will be updated and the page may not appear always at the same position while searched.
You can check the below options to check how your site is performing and indexed by Google.
- Site:[Site Name]
Example- type in google search bar, site:kidsunfold.com. Will list all the pages which are indexed.
- Cache:[Site Name]
Example- cache:kidsunfold.com. Will display the cached and indexed version of the homepage along with the information when it was cached.
- Link:[Site Name]
Example- link:kidsunfold.com. Will list all the pages that link to your site’s home page. This gives an idea of the active backlinks of your site for that google has the information.
- Related:[Site Name]
Example- link:kidsunfold.com, will list all the sites which are similar to your searched page.
Pay attention so that google can keep and store the relevant information of your sites to help appearing while searched.
- Allow Google to crawl your site information
Check the robots.txt file and crawl errors for your site. Also keep the Sitemap file for your site.
- Allow Google to index your site
Keep the key content tags like title tag, alt attribute relevant and proper.
- Follow the content guidelines by Google
Use the proper keyword, html guidelines and also the proper size and quality of image un your sites.
