Google Milestones
Google Milestones
According to Google lore, company founders Larry Page and Sergey Brin were not terribly fond of each other when they first met as Stanford University graduate students in computer science in 1995. Larry was a 24-year-old University of Michigan alumnus on a weekend visit; Sergey, 23, was among a group of students assigned to show him around. They argued about every topic they discussed. Their strong opinions and divergent viewpoints would eventually find common ground in a unique approach to solving one of computing's biggest challenges: retrieving relevant information from a massive set of data.

Reason to Ranking Drop
1. Your website changes
Most webmasters update their web pages regularly. As long as the changes are only small, this won't have a big effect on your rankings. However, if you re-design your web pages or if you optimize a page for a new search term then search engines might re-calculate your search engine rankings.
Google even has a filter for changed web pages. If you change your web pages, Google will temporarily apply a filter to your sites. Details can be found here.
Required action: If you have web pages with high search engine rankings then you should change these pages with great care.
2. The links to your website change
If you have an old website with a grown inbound link structure then it's not likely that your site rankings will drop because of a link change.
If the links to your site are mainly paid links that suddenly disappear or get discounted by Google then the loss of these links can be enough to cause a significant ranking drop.
In addition, sudden changes in the linking structure of a website make your website suspicious.
Required action: If you heavily rely on paid links you might want to reconsider your linking strategy. Try to get inbound links that last.
Continually getting links is essential to keep high rankings. If you don't work on your links then your website will be replaced by better linked web pages in the search results.
3. The websites of your competitors change
Everybody wants to be on Google's first result page. For that reason, it's only natural that other websites will be listed better than yours if you don't react.
Many websites target the same keywords as you do. If these other websites have better content and better links than your site then it's only natural that these sites get better rankings.
Required action: You must offer better content than your competitors. Make sure that you offer many web pages that are relevant to your search terms and that you have better inbound links than your competitors.
4. Spam elements on your web pages
Search engines don't like spam. If search engines find out that you use cloaking, hidden text, doorway pages or any other spam technique on your web pages then it is extremely likely that your website will be penalized.
Required action: Remove all spam elements from your web pages. Just because your website hasn't been penalized yet doesn't mean that search engines won't find the spam elements in the near future.
5. Search engine algorithm changes
Search engines are continually improving their ranking algorithms. While most changes are rather subtle, some ranking algorithm changes can have a major impact on the rankings of your web pages.
Required action: Wait for some days to find out if the ranking drop is not just temporarily. Then optimize your web pages so that they reflect the latest search engine algorithms.
6. Technical problems
Your web server can be the reason for a ranking drop. If your website is down when the search engine spider tries to access your website then search engines cannot give your web pages high rankings because they don't know your pages.
Some websites display the correct web page in the web browser but the server returns an error code. In that case, search engines won't index the web pages.
Required action: Make sure that your website is hosted on a reliable server that has no downtime. Check the HTTP status code that your website returns.

Link Building / Link Popularity
Link Building/Link Popularity
PageRank is the measure of importance Google assigns to a Web page on a scale of 1 to 10.
You can check the PageRank value of every page you visit by downloading the Google Toolbar.
Google’s founders, Sergey Brin and Larry Page, formulated a Search Engine algorithm that shifted the ranking weight to off-page factors. They developed a formula called PageRank, in which the algorithm counts the number of sites that link to a page and then assigns the page an importance score on a scale of 1-10. The higher the number and importance of sites that link to your page, the higher the PageRank of your Web site.
What is Link Popularity?
Link Popularity refers to the number of links pointing TO your site FROM other sites on the Web.
The Search Engines consider your site more important and rank it higher if several other sites link to your site.
Quality links means links from related pages and with high rankings in search engines.
Building Quality and Relevant back links is a dual advantage where you attract vistors from the reciprocal linking site and simultaneously boost your websites Page Rank.
Types of links
There are two types of links you can establish on the web:
Reciprocal links
Link exchange is an easier way to establish links from other websites to your website.
In link exchange process, you trade links with prospective partner sites by offering a link to their site from your own site.
This method is a fast way to establish several hundred links to your website. However, it may not get you great benefits.
Reciprocal links
Both sites link to each other
One-way links
To establish ‘only-incoming’ links also called ‘one-way links’ or ‘Non-Reciprocal links’.
Only incoming links are the links established on the other websites where you do not need to link back to them.
Inbound links
Site A receives a link from Site B
There are various compelling reasons and methods to establish such one-way links which include linking back from a different website that you may own, publishing articles on sites, content syndication, listing in trade directories and giving out press releases in news networks.
Outbound links
Site A links out to Site B
Kia Dealers - Get multiple Kia price quotes from competing Kia Dealers
Used Autos - Autotropolis.com is your #1 stop for auto reviews and comparisons on new automobiles and trucks.
Calculating percentage OR Bounce Rate
Bounce rate is expressed as a percentage. To calculate bounce rate, take the number of single-page visits and divide by the total number of visits, then multiply
by 100.
Vsp = Visit of Singe Page/Single time
Vt = Visit of Total page
If, on one day, a page receives 335 visits and 320 are bounces, and the next day receives 950 visits and 720 bounces, the bounce rates would be 95.5% and 75.8%, respectively. Although on the second day, the page had more bounces numerically, the bounce rate expressed as a percentage makes it easy to compare the data meaningfully and to see that the second day had a more favorable bounce rate.
