Search engine ratings, such as Google and Yahoo, are based on computer formulas (algorithms). The formulas give an estimate of how satisfied a search engine is with various websites. For example, someone from Topeka, looking for a general contractor to rebuild their kitchen, will be most satisfied with the sites of high-quality general contractors that serve Topeka.
The key factor in the formulas used by search engines is the “popularity” of the website among other sites on related topics. For example, when evaluating a website called "Joe & Sanitary", a search engine can determine its popularity on websites for home improvement and other similar topics. The search engine counted the number of relevant sites that bothered to associate with Joe's Sanumbing. From the point of view of Joe's Sanumb, each of them is a “feedback”.
If there are 500 backlinks on the website, the search engine counts 500 “votes” for the website. If there are more votes than other plumbing websites, especially if the votes are taken from sites that are considered to be plumbing, the Joe's Sanumb website will be rated high when the seeker is looking for a plumbing contractor.
Of course, with local businesses such as plumbing, the search engine will only compare sites that serve the same area. Search engines assume that someone in Seattle searching for a plumber wants someone to be local will show the search for the most popular sites of numbers in Seattle. Using search engine optimization (SEO), a Seattle plumbing company can change its site and provide it with backlinks so that it is high ranking among those who have been shown to the search user.
Relevance of the linking site
Search engines not only link to backlinks, but also point out the relevance of the binding site. The back link from the site, called, for example, “Home Improvement”, will be the relevant link for the electrician's website. A link back from the baseball card website will not be up to date. His voice will not be counted.
The power of the binding site
More important than relevance, is “authority ". Google takes into account aspects of the “credibility” of the website and summarizes them and the age of the website as a measure called “PageRank”. Why the age of the site? Older websites have proven that they do not work at night.
The Google search engine publishes PageRank from many web pages, especially home pages. PageRank runs from “unranked” below, then from 0 to 9, with 9 being the highest score. Most sites without a rating or rating of 0. Very few, such as the home pages of Wikipedia.org and Yahoo.com, rank in 9.
Most contractor sites are ranged from 0 to 3. A high-quality website that has been on the Internet for several years and has many backlinks can expect to reach PageRank 2. If your contractor site has PageRank 3-5, you really do a lot of things for a long time!
You can find out the PageRank of your website, as well as websites that link to it with special software. I use free software called “SEO Toolbar” from the “Tools” section of SEOBook.com. SEOToolbar can be downloaded into the Internet browser "Firefox".
You will notice that when using the PageRank tool, almost always a high PageRank value is added to the home pages, but not to the internal pages. For example, on the main page of Wikipedia.org there is currently PageRank 9, but on the Wikipedia page on the “dog” there is currently PageRank “only” 7.
Most often, Google leaves the internal pages unchanged. Google employees maintain confidentiality in most of the work of their search engine. Thus, no one knows with certainty the credibility of the reciprocal link from the unconfirmed internal page of the website with a high PageRank page. However, many SEO experts believe that backlinks from internal pages elevate some of the authorities on the main page.
This is useful for ranking in search engines in order to have high google pagerank. This is also useful for getting back links from high PageRank sites. Of course, if you could get a link from the main page of Wikipedia with its PageRank 9, it would be great - and it would be difficult, if not impossible. But getting backlinks from web pages using PageRank 2-7 depends very much on the possibility.
Backlink strategies
Knowing the importance of quality backlinks for search engine rankings provides targets for SEO surveys. SEO also requires link building strategies, such as getting listings in builders; directories or publishing articles in online journals with links to your contractor site. Developing link building strategies is the next step in SEO.
