Let’s try to put ourselves in shoes of online search engine owners and creators. A few years earlier, a directory site submitting to thousands of other sites required a great deal of work, time and determination.

After the software and online scripts, which immediately submit pages to directory sites, appeared, getting hundreds or countless links in a short time period is not a problem anymore. At the same time, the variety of websites is growing every day and it increases competitors for particular keywords. The search engines need to find sites which best fit to the search phrase from countless websites.

Due to the above mentioned aspects, the creators of search engines were forced to utilize unique filters. In their opinion, on the one hand, the inflow of the large number of useless links from websites submitted to the countless directory sites is limited, and the focus is just on these which show the genuine quality of the page.

On the other hand, just these sites, which best fit the topic of the search, are fund. For that reason, nowadays it is better to have our one or two links on quality websites than one hundred in useless directories.

At the same time, much attention ought to be paid to the optimization of keywords, which still is main factor of determining the style of the site.
