Additionally, paid inclusion spiders will go back to your pages often, sometimes even daily. The advantage of this is that you can update your pages constantly to improve the ranking in which they appear in search engines, and the paid URL  inclusion spider will show that result in a matter of days. First and foremost, the disadvantage is the cost. For a ten page website, the costs of paid URL inclusion range from $170 for Fast/Lycos to $600 for Altavista, and you have to
pay each engine their annual fee. How relevant the cost factor is will depend on your company. Another, and perhaps more important, disadvantage is the limited reach of paid URL inclusions. The largest search engines, Google, Yahoo, and AOL, do not offer paid URL inclusion. That means that the search engines you choose to pay an inclusion fee will amount to a small fraction of the traffic to your site on a daily basis.
Google usually updates its index every month, and there is no way you can speed up this process. You will have to wait for the Google spider to index your new pages no matter how many other search engines you have paid to update their index daily. Be aware that it is only after Google updates their index that your pages will show up in Google, Yahoo, or AOL results. One way to figure out whether paid URL inclusion is a good deal for your company is to consider some common factors. First, find out if search engines have already indexed your  pages. To do this, you may have to enter a number of different keywords, but the quickest way to find out is to enter your URL address in quotes. If your pages appear when
you enter the URL address but do not appear when you enter keywords, using paid inclusion will not be beneficial. This is because your pages have already been indexed and ranked by the regular spider. If this is the case, your money would be better spent by updating your pages to improve your ranking in search results. Once you accomplish this, you can then consider using paid inclusion if you want to speed up the time it will take for the regular spider to revisit your pages.
