Submitting To Crawlers: Google, Yahoo, Ask/Teoma & Microsoft's
Crawler-based search engines automatically visit web pages to compile their listings. This means that, unlike directories, you are likely to have several if not many pages listed with them. This also means that by taking care in how you build your pages, you might rank well in crawler-produced results.
Submitting To Google
One of the most important crawler-based search engines is Google, because many people search at it, plus it "powers" the main results of several other services.
The absolute best way to get listed with Google is to build links to your web site. Indeed, this is the best way to get listed for free with all the major crawlers listed on this page. Crawlers follow links, so if you have good links pointing at your web site, the crawlers are more likely to find and include your pages.
Here's the good news: if you submitted your site to the major directories and got listed with one of them, then Google and other crawlers will almost certainly pick up the URL that was listed. This means you may not need to do additional work to get listed with crawlers.
Aside from link building, Google provides an Add URL page that lets you submit a URL directly to its crawler. There's no guarantee that Google will actually include a URL submitted to it this way, however. Despite this, it makes sense to submit your home page and perhaps one or two other URLs from "inside" your web site via the Add URL page.
You really don't need to submit more than this. The only reason for submitting some of your inside pages is in case there is a problem reaching your home page. This gives Google an alternate route into your site. From whatever page it visits, it will look for links to other pages that you have and perhaps include those. This is true for other crawlers, as well.
If you have a brand new web site, it will probably take about a month before Google lists your web pages. Because of this, you might consider making use of its paid placement program, which is covered in the next part of this guide.
