When your webdesign is finished, you can begin with optimizing your site. Through spiders, search engines are able to index websites. Through submitting your site, the spider will go to the site and search through all the pages and index them. Your website content, meta tags, and links will all be examined on your site by the spiders. The spider will deposit the information it gathered where your data is being indexed. Any pages you link to will be indexed, as well. Sites with hundreds of pages could be a problem, however, because spiders only index a limited amount of pages.
The spider does return frequently back to your site to see if there has been any updates or changes. Exactly how often those returns take place is determined by the search engine moderators. Much like a book has a table of contents, actual content, and a reference section, so does a spider, though its references are links to other sites. The indexing power of a spider can reach up to a million pages per day, in the cases of Excite, Lycos, AltaVista, and Google.
To get an improved search engine placement, whenever someone types in keyword into the search engine, the search engine actually finds the information that is closest to what the searcher is typing in their internal index. Thus, if your web page has the keyword “buy management book” listed in the search engine index and a searcher types in that keyword, then your web page will come up in the first page of results. Every search engine uses a different algorithm to search their indexes, so you will get different rankings depending on which algorithm is used.
