If you're interested in buying links from web directories so that your sites will rank with the search engines, there are a number of factors you will want to take into consideration. First, there are a large number of directories available on the web. While some of them are high in quality, many of them are not. As an online business person, you must maximize your available resources, and this means you can't afford to waste even small amounts of money on a directory that does not give you a good return on your investment. Before you spend money on a directory link, you must first run that directory through the proverbial "acid test."

The first thing you will need to find out is who links to the directory. Does the directory have a single link that companies from a bunch of medicine sites? If the answer to this question is less, this is a sign that you will want to avoid paying for their service. The search engines place a high emphasis on the quality of your inbound links, and you cannot afford to waste money on directories like this. Never buy a link from a directory until you've analyzed their inbound links to make sure they are high in quality. After looking at who links to the directory, you will want to next look at who the directory links to.

It is possible for a scam link directory to buy hundreds of outbound links to make it look like the site is high in quality. Search engines place a great importance on the quality of outbound links, so it is important for you to analyze the outbound links of the directory. If these links are low in quality, this should tell you whether or not you should pay for a link in their directory. It is also important for you to make sure the category pages have been crawled by the search engine spiders. Many low quality directories will only have their homepages crawled, and this is something you will want to avoid at all costs.

Another factor you will want to look at is how often the directory is crawled. If a site is crawled on a regular basis, this is a sign that the search engines trust it. If it is not crawled frequently, this means the SEs don't trust it, and you shouldn't either. It is also important for you to determine whether or not the directory is valuable to human visitors. It is not enough for a site to be useful for the search engines. It must also cater to the needs of those who visit it.
