The task of website analysis for promotion in different search engines is usually solved by the means of various online services and software products. It is better to use a mashup approach, when you get all results of the web server log analysis on the same platform, thus eliminating the need to buy a set of various software products or pay for multiple online services.

Web crawler visit frequency and depth are calculated by a set of adaptive algorithms that the search engine developers prefer not to disclose. When you run an advertisement campaign to promote your goods or services over the Internet, or even just update your website content, it is important to understand in what way and how fast these changes will be seen by the search engines.
