Search engines are one of the primary ways that Internet users find Web sites. That’s why a Web site with good search engine listings may see a dramatic increase in traffic.
Everyone wants those good listings. Unfortunately, many Web sites appear poorly in search engine rankings or may not be listed at all because they fail to consider how search engines work.
In particular, submitting to search engines is only part of the challenge of getting good search engine positioning. It’s also important to prepare a Web site through “search engine optimization.”
Search engine optimization means ensuring that your Web pages are accessible to search engines and are focused in ways that help improve the chances they will be found.
How Search Engines Works
The term “search engine” is often used generically to describe both crawler-based search engines and human-powered directories. These two types of search engines gather their listings in radically different ways.
Crawler-Based Search Engines
Crawler-based search engines, such as Google, create their listings automatically. Their robots “crawl” or “spider” the web, then people search through the listings found by the robots.
If you change your web pages, crawler-based search engines eventually find these changes, and that can affect your listings. Page titles, body copy, links and other elements all play a role.
Human-Powered Directories
A human-powered directory, such as the Open Directory Project, World Web Directory and CoolSeller Directory depends on humans for its listings. You submit a short description to the directory for your entire site, or editors write one for sites they review. A search query looks for matches only in the descriptions submitted.
Changing your web pages has no effect on your listing. The elements that are useful for improving a listing with a search engine have nothing to do with improving a listing in a directory. The only exception is that a good site, with good content, might be more likely to get reviewed for free than a poor site.
The Parts Of A Crawler-Based Search Engine
Crawler-based search engines have three major elements. First is the spider, also called the crawler. The spider visits a web page, reads it, and then follows links to other pages within the site. This is what it means when someone refers to a site being “spidered” or “crawled.” The spider returns to the site on a regular basis, such as every month or two, to look for changes.
Everything the spider finds goes into the second part of the search engine, the index. The index, sometimes called the catalog, is like a giant book containing a copy of every web page that the spider finds. If a web page changes, then this book is updated with new information.
Sometimes it can take a while for new pages, or changes that the spider finds, to be added to the index. Thus, a web page may have been “spidered” but not yet “indexed.” Until it is indexed — added to the index — it is not available to those searching with the search engine.
Search engine software is the third part of a search engine. This is the program that sifts through the millions of pages recorded in the index to find matches to a search and rank them in order of what it believes is most relevant.
Hybrid Search Engines” Or Mixed Results
In the web’s early days, it used to be that a search engine either presented crawler-based results or human-powered listings. Then it became common for both types of results to be combined in a hybrid search engine favoring one type of listing over another. For example
- Meta Robots Tag
- Frames Support
- robots.txt
- Paid Inclusion
- Full Body Text
- Stop Words
- Meta Description
- Meta Keywords
- ALT Text / Comments
 We will discuss these elements in the next post.
