Seeing so many subscribers still interested blog, i have decided to keep posting here. So welcome come back and let us learn more together. I am going to talk about the external factors can influence the search engine rankings of a web site today:
-Quantity, quality, and relevance of inbound links
- Link churn
- Link acquisition rate
- Link anchor text and surrounding copy
- Reciprocal links
- Number of links on a page
- Semantic relationships among links on a page
- IP addresses of cross-linked sites
-TLD of domain name for a link
- Link location
- Web standards compliance
- Detrimental “red-flag” factors
Quantity of Inbound LinksA site with many inbound links is likely to be relevant because many people voted for it by placing the link on their sites. There are some caveats here with regard to whether the links are detected to be part of an artificial link scheme, and quality is also a concern as explained in the next section. However, more is generally better.
Quality of Inbound LinksA popular web site that links to you prominently that itself has many inbound links and a good reputation is likely to mean more than a link from a random page from an unimportant web site with few links. There is no absolute definition that describes "quality." Search engines themselves struggle with this definition and use very complicated algorithms that implement an approximation of the human definition. Use your judgment and intuition.
Relevance of Inbound LinksA search engine is likely to view a link from a semantically related web page or site as more valuable than a link from a random unrelated one. Usually, a series of links with very similar anchor text from unrelated sources is an indicator of an artificial link scheme, and they may be devalued. Too many links from irrelevant sources may result in a penalty. This has led to speculation that competitors can hurt your web site by pointing many such links to your web site.
Link ChurnLinks that appear and disappear on pages are likely to be part of a linking scheme. The rate at which these links appear and disappear is termed “link churn.” If this happens frequently, it may be regarded as spam. Those links will either be devalued, or at worst your web site will be regarded as spam and penalized. Unless you are participating in such a scheme, this should probably not be a concern.
Link Acquisition RateAn algorithm may view the acquisition of many thousands of links by a new site as suspicious, if not also accompanied by relevant highly ranked authority sites. Usually this is an indicator of a linking scheme. This consideration was affirmed by Google engineer Matt Cutts in one of his videos at http://www.mattcutts.com/blog/more-seo-answers-on-video/.
Link Anchor Text and Surrounding CopyInbound links that contain semantically related anchor text to the content they point to have a positive effect on rankings. The copy surrounding the link, if present, may also do the same. Some even posit that this copy is as important as the link anchor text itself. Links with such surrounding copy are widely believed to be valued more by search engines, because links without copy surrounding it are frequently purchased and/or less indicative of a vote.
I will discuss more tomorrow, so keep an eye on it.
