A listing in these search engines is a necessity for any aspiring webmaster. The following 30 search engines are not only the largest and most popular of their kind, but many are listed amongst the top 100 sites on the entire Web! Systematically following this list should help you to generate a significant amount of traffic in very little time (and with very little expense).

AAA Matilda is a popular search engine that is updated hourly and searchable by geographical location.

Alta Vista is perhaps the most popular spider-driven search engine on the 'Net. While Digital's Alta Vista software will theoretically, over time, index every page on the Net, it is useful to submit your site to the spider. By submitting your site's index page, Alta Vista will automatically list all pages connected to it, effectively indexing your entire site. The employment of META tags will increase the chances that your site will be hit on a search.

AOL NetFind is another popular spider-driven page index, powered by Excite's search software. Submitting your top-level page will set the spider in motion as it indexes your entire site.

Business Seek is a large, searchable database of businesses. As such, only business listings will be considered.

ComFind is reportedly the Internet's 'largest global business directory', listing only business sites.

CyberSpider is a well-organised directory and search engine. At present, Cyberspider is still relatively new to the Web, listing relatively few sites in its Yahoo!-like layout. One interesting feature about the CyberSpider site is that it counts the number of hits that each of its links have generated, displaying them publicly next to each site's details.

Excite is one of the top five major search engines on the Web. Both a categorised directory and a keyword-driven search engine, Excite lists over 1.5 million databases, including reviews of more than 35,000 sites.

Galaxy is one of the five top directories on the Web. Sites are categorised by subject.

GoTo.com is "site finder" which provides users with the fastest, easiest and most user-friendly way to find the most relevant web sites on any topic. It is both a search engine and a directory, seen by more than 2 million web surfers each month.

HotBot is another popular spider-based search index, and one which is particularly easy to use. It's also said to be the 'most complete' web index, listing more than 54 million documents. Simply submit one URL and your entire site will be indexed within days.

ICN Internet Explorer is the official search page of the Internet Explorer browser, and is certain to increase dramatically in popularity. Sites are arranged into categories, as specified by the webmaster, and are searchable using a keyword-based search engine.

Infoseek is one of the top five search engines on the Web, and one of the oldest, listing over 20 million URLs. Its automated search-robot that will list your site within minutes of submission. Note that sites hosted on free servers (such as Geocities and Tripod) and sites with binary addresses will not be listed.

Jayde Online Directory is one of the fastest-growing search engines on the Net. Jayde's 40 categories are easy to navigate, and a keyword search is also provided. Submission to Jayde's index may take a few weeks to process.

LinkMonster is a well-organised, colorful Web site search engine and announcement generator, browsed by millions of surfers each month.

LinkStar is another popular online business directory. It only lists businesses and companies, each listing displayed as an 'e-Card', packed with details about the organisation. Since this is strictly a business listing, similar to a business card file, a URL does not have to be included in the submission.

LookSmart has been set up as both a directory that you may 'Explore' (containing thousands of categories and sub-categories), and as a searchable database of approved entries. The search function also links to Alta Vista's huge listing if it fails to produce the desired results. It is best if you browse the site prior to submission in order to locate the appropriate category and sub-category in which you wnat your site to appear. There is a link to click on in each category to add a site.

Lycos is a well-respected and increasingly popular search spider. Lycos also lists thousands of sites in its categorised Web guide.

Magellan gives surfers the opportunity to search from the entire Web, from only the sites reviewed by Magellan, or only a select group of quality sites. Magellan's submissions are handled through the Excite database, though I imagine that suggesting your URL from Magellan's form may increase the chances that your site will receive a review.

Nerd World Media has established a popular Web directory and search engine. The directory arranges sites by subject.

Northern Light is one of the newer search engines to make a big mark on the Net. Already, it has indexed over 30 million sites. Yours could be next.

OneKey is the largest guaranteed error free, kid-safe search engine on the Net. All sites that wish to be listed at OneKey must have G-rated content and, preferably, no commercial content. Sites that contain ads will be marked as such in order to help children discern between 'real' content and commercial content. OneKey reserves the right to edit and/or delete your submission if it doesn't suit their content requirements.

Pronet Goldlink Directory is the Web's first, and still one of its biggest, international corporate directories. Pronet lists business sites from 175 different countries and 65 market industries.

Scrub The Web is an increasingly popular spider-driven search engine that allows surfers to search the entire Web, or to limit their search to sites within a particular category. The link submission process is quick and easy. Soon, Scrub the Web is planning to launch 'Super Scrub', a robot-search that has apparently already indexed over 80 million pages.

Snap! Online is a new, but very popular net guide designed in a similar fashion to Yahoo!. At this stage, submissions to Snap! must be made via an email request.

Starting Point is, indeed, a great place to start when promoting your site. As well as featuring some of the Web's finest sites in their "choice sites" sections, Starting Point features a list of the most recent sites added to their database which, usually, generates a short, but effective, burst of traffic.

The Net1 is actually four search engines in one. You may add your URL to either their 'consumer search', 'professional search', 'business opportunity search' or their 'adult search'.

WebCrawler is a spider-driven search index listing millions of sites. It is also one of the top 10 search-engines on the Net, according to traffic reports.

WebDirect! is a business-oriented yellow-pages type search engine/directory. Upon submission of your business listing, you are permitted to enter your data into 10 of 2700 content-specific categories.

WhatsNew.com allows you to list your site by category and location, with listings updated hourly. The Excite What's New? section seems to be affiliated with WhatsNew.com.

Yahoo! is not only the long-standing most popular search utility on the Web, it is also one of its most popular pages. A listing in Yahoo! can take a matter of months to process and appear, but it is worth the wait to appear in the Web's premiere directory. The best way to submit your URL to Yahoo! is to browse the site's categories until you find the page where you want your listing to appear. Then click on the "Add URL" icon and fill in your information. Yahoo! allows you to add your URL to up to two distinct categories.

The follow list contains 126 additional search indices to help generate more traffic for you. Note that some of these sites are content-specific, meaning that while some sites won't be able to be listed, others may receive great benefit from a listing on a site specifically targetted towards their audience demographic.
