Back links - It’s Not Quantity, It’s Quality
I am going to talk about Google back links as Google is considered as the most important among all other search engines.ÂÂ
If you are trying to rank for Google, you are going to need more patience.   You would not expect any new website to rank for a very competitive keywords for at least months.   During the Jagger update in November 2005, Google has changed its algorithm in ranking websites and only their engineers know exactly what has been changed. According to the studies made by search engine companies, the following aspects believed to have changed during the update:
1. Value of your website’s incoming links
2. The anchor text used in the incoming links
3. Content of the page of incoming links
4. How keyword are used in the anchor text
5. Age of the incoming links
6. Relevancy of the sites linking to you
7. Directory links
8. Value of reciprocal links
9. Sandbox effect / age of your site, domain registration date
10. Number of pages your site have.
11. Frequency of fresh content update
12. Canonical / sub domains, sub-sub domains
13. IP numbers of sites linking to your site
14. Duplicate content on same site or on multiple domains
15. Over-optimization, excessive text markup
16. Readability of your site to search engine robots.
