Marketing To Search Engines
What can we know about SEO SEM marketing.
To search, we use programs which are called Search Engines, Spiders, Crawlers, Knowbots etc.. Thereare currently three types of search engines:
a) Crawler-based search engines,
b) Human-Powered directories,
c) Hybrid Search Engines.
The heart of the search engine is a recursive procedure process_url, which takes a URL strings as input. It operates as follows. First, it hashes the URL to see if it is already present in url_table. If so, it is done and returns immediately. Each URL is processed only once. If the URL is not already known, its page is fetched. The URL and title are then copied to the heap and pointers to these two strings are entered in url_table. The URL is also entered into the hash table. Finally, process_url extracts all the hyperlinks from the page and calls process_url once per hyperlink, passing the hyperlink’s URL as the input parameter.
One of the example of Crawler-based Search Engine is Google. It creates listings automatically. Crawling the web they list their findings and then the user search from their findings. Human-Powered directories is as it states in meaning. Powered by human or depends on human for listings.
In this way, the site description is submitted and then it’s matches are found. Here, we should say that in Crawler-based search engines it does matter if you make changes in your web pages.
But in Human-Powered search engines it does not take effect.
In Hybrid Search Engines both types of searches and listings are available. SEO website stands for Search Engine Optimization, it follows the basics: search engine friendly site design and architecture, and the fundamentals of keyword research and content development.
