How Do Search Engines Work - Web Crawlers
It is the search engines that finally bring your website to the attention of your prospective customers and clients. Which means it is better for your website performance if you know how search engines actually work and how they present information to the customer initiating a search.
There are basically two types of search engines. The first is by robots called crawlers or spiders.
Search Engines use spiders to index websites. When you submit your website pages to a search engine by completing their required submission page, the search engine spider will index your entire site. These automated programs are run by the search engines. When a spider visits a web site, they read your actual web content, Meta tags and follow the links that your site connects to.
The spider then returns all that information back to a central depository, where the data is indexed. It will visit each link you have on your website and index those sites as well. Some spiders will only index a certain number of pages on your site, so don’t create a site with 500 pages!
The spider will periodically return to the sites to check for any information that has changed. How often this happens is decided by the search engine. A spider is almost like a books table of contents, the actual content and the links and references for all the websites it finds during its search, and it may index up to a million pages a day.
When you ask a search engine to locate information, it is actually searching through the index which it has created and not actually searching the Web. Different search engines produce different rankings because not every search engine uses the same algorithm to search through the indices.
One of the things that a search engine algorithm scans for is the frequency and location of keywords on a web page, but it can also detect artificial keyword stuffing or spamdexing. Then the algorithms analyze the way that pages link to other pages in the Web. By checking how pages link to each other, an engine can both determine what a page is about, if the keywords of the linked pages are similar to the keywords on the original page.
Submitting Your Website to Search Engines
If you have a web-based business or if a significant portion of your business is done on the web through your website, then the best advertising and marketing is done by submitting to a search engine. No amount of press release, newspaper or radio ad, banner ad, spam email or newsletter will achieve the same results, although, maybe effective in a small proportion.
Beware of companies that promise automatic submission of your website to hundreds of search engines which are but only false promises. The best way to submit your website for search engine ranking and inclusion is to do it yourself or to hire an expert to do it manually, by contacting the search engine companies and directories.
Before you begin to submit your website to search engines ensure your websites are thoroughly designed to the professional quality using the right key words, good graphics and pictures and the relevant content. Don’t submit websites that are incomplete. While submitting to a search engine, make sure to provide information about your website, keywords and any other information that may be pertinent, including the name and contact information of your business.
Mere submission to search engine companies does not guarantee that your site would be immediately listed, and the ranking will be high. Because there are thousands of new websites coming up every day and it may take quite some time before they take up your site for review by human editors. One important factor to remember while submitting site is to include a site map of your website which makes the crawling easy for the web robots. Search engines like ‘http://www.google.com’ hardly considers submissions without sitemaps.
There are many online companies that accept search engine submission services. You can choose to do it yourself with a software package and service. There are thousands of search engines and directory companies, where you can submit your website, you get to submit to as many companies as you want.
