When you begin the task of acquiring quality and relevant backlinks to your website there are many factors that can increase or decrease your search engine rankings. This article outlines the difference between good and bad backlinks.
A quality backlink pointing to your site should be in the same category and relevant in content to your website. The page where your link is located should be indexed by Google and the page should also have a Google page rank. The webpage where your link is located should also contain no more than 30 other out-going links to other websites. Link pages with more than 30 out-going links are less relevant to the search engines. Having your link posted on this type of webpage can affect your search engine rankings in a negative way. Other excellent techniques of acquiring backlinks are directory submissions, posting articles, blogs and forums.
For directory submissions select the proper directory category and take a look at how many other websites are contained in the category where your link would be posted, if you can manage to get on the first or second page of the listings, this is a quality backlink. Also look at the Google page rank of the landing page for your link. If the page has a Google page rank this is also a quality backlink.
Stay within your category, relevant content is very important to the search engines. Write an article preferably relevant in content to your website and submit the article to high quality article directories. Blogs are an excellent way to get quality one-way backlinks, Blog sites also receive tons of traffic, which in turn give your site more exposure. Posting your link on forum pages is also an efficient method of aquiring backlinks instantly.
Backlinks to avoid would be a zero page ranked webpage, especially if the home page has a zero page rank. Links posted within framed webpages which will also steal your traffic. Especially avoid link farms, webpages which contain more than 100 unrelated outgoing links, This type of link page is frowned upon by many major search engines. Avoid Webpages with mirror sites containing the exact same content with a different URL, also pages that utilize redirects and URL cloaking. Never post your link on a webpage that contains a “no follow” or “no index” robots meta tag within the source code. Dynamic websites with question marks in the URL should be avoided because they are not always indexed by the search engines.
Avoid posting your link on a page that opens very slow or contains mostly ads and flash banners. Try not to aquire or purchase great numbers of backlinks in a short period of time, backlinks should be accumulated gradually. Also avoid webpages and directories that list their results in alphabetical order, as their database increases your link could be moved to a less relevant page with less pagerank. Quality backlinks are one of the most important factors involved in the process of acheiving high search engine ranking.
