The majority of search traffic comes from the top five or so search engines. Some companies will offer to submit your site to "thousands" of search engines. This is a waste of money. If your site is linked to from anywhere, you'll get in all the search engines that matter, automatically, for free.
Submission means filling out a form on a search engine's site to invite them to add your site to their index. What many people don't realize is that this is unnecessary. Engines find what's on the web by following links. As long as there's a link to your site from any site that's already in the search engines, the engines will find your site. If you don't have any incoming links you're not going to rank well anyway.
Search engines use automated robots to follow the links around the web and grab the content from the web pages they find. The robots are called spiders, and when they follow links they're crawling the web (also called spidering). Google's spider is called Googlebot, and you'll see it listed as the user agent in your server logs. Once a search engine has gathered a site's data and analyzed it the site is said to be indexed. To see whether your site is in the Google index, search Google for site:yourdomain.com.
New sites don't always get listed right away. In some cases it can take several months for a new site to show up in the SERPS. Even when a site gets in the index, Many believe that Google puts new sites "in the sandbox" and won't let them rank well for the initial few months. Jennifer Laycock has a better explanation: New sites can rank fine if there's not much competition for that topic, but Google will assume that a new site in an established, competitive market isn't any better than the tons of sites already there, unless that site proves itself to be superior. (More in this discussion thread.) The sandbox issue has been discussed on Webmaster World ad nauseum. (Searching WebmasterWorld for all pages mentioning the sandbox results in nearly 1000 hits at present.)
Google appears to visit most pages in its database at least once a month, though it may take longer. Some pages get visited every day. Sites with a higher PageRank (i.e., sites that have a lot of inbound links from other sites) get spidered more frequently than sites with a low PR. And sites which update more frequently get spidered more often than sites which rarely make updates. You can try to invite more frequent spider visits by updating your pages more frequently, even if the changes themselves are minor and negligible, though there is questionable advantage in doing so. This won't necessarily let you test your page ranking ideas through trial and error any faster because even if an engine spiders your new content to see what you have on your page, it won't necessarily figure out how those changes should affect your rank for weeks or months. And of course, more frequent spider visits by themselves do nothing for your rankings.
Search engines find pages by following HTML links. As long as the pages on your site are linked up properly the engines will find them. But if your pages aren't linked properly, your pages will never make it into the index. Here are some typical things that can cause an engine to fail to find your pages.
Orphaned pages: If you forget to link to a certain page from at least one other page, that page page is said to be orphaned. An engine can't find it because it can't follow a link to it. Make sure every page on your site is linked to from at least one other page.
Dynamic pages: Search engines can generally follow dynamic URLs (those with a question mark) as long as the have only one or two parameters. Three parameters -- hard to say. Four or more parameters is probably pushing it. But even if the engines can follow dynamic URLs, that doesn't necessarily mean that those pages will rank well.
Site is down: An engine can't index a site if it's down. Make certain you use a reliable webhost. (You can also use monitoring software or subscribe to an automated monitoring service to email, phone, or page you if your site goes down.) It's unlikely that you'll be removed from an engine just because your site was down once when they tried to visit, but if your site is down for several days that could spell bad news. An engine doesn't want to list your site in the SERPs if visitors can't actually get to it.
Images and Frames: Search engine spiders can follow image links and links in framesets just fine -- depsite what you sometimes read on the net..
