Getting Your Web Site Listed Danny Sullivan Editor, Search Engine Watch http://searchenginewatch.com/ Session’s Goal  Cover the best way to increase the percentage of your web site listed with crawler-based search engines  Discuss importance of submitting to human-powered directories  Not covering issues of improving ranking! Types of Search Services  “Search engines” crawl the web and read your web pages  “Directories” like Yahoo depend on human-provided information to categorize sites  Most search services are a hybrid of both, but more dominant in one area How Search Engines Work  Read pages they find on the web  Store text in an “index”  When you search, they look for pages with matching text  Other factors involved in “ranking” those pages, such as “link popularity” The Major Search Engines         Northern Light (big, but low traffic) FAST Search (big, but even less traffic) AltaVista (big and popular) Inktomi (HotBot, UK Max) Google (Netscape Search) Excite (WebCrawler) Go (Infoseek) Lycos (links at end) Submitting To Search Engines  Search engines should find you naturally, but submitting helps speed the process and can increase your representation  Look for Add URL link at bottom of home page  Submit your home page and a few key “section” pages  Turnaround from a few days to 2 months Deep Crawlers  AltaVista, Inktomi, Northern Light will add the most, usually within a month  Excite, Go (Infoseek) will gather a fair amount; Lycos gathers little  Index sizes are going up, but the web is outpacing them…nor is size everything  Here are more actions to help even the odds… “Deep” Submit  A “deep” submit is directly submitting pages from “inside” the web site – can help improve the odds these will get listed.  At Go, you can email hundreds of URLs. Consider doing this.  At HotBot/Inktomi, you can submit up to 50 pages per day. Possibly worth doing.  At AltaVista, you can submit up to 5 pages per day. Probably not worth the effort.  Elsewhere, not worth doing a “deep” submit. Big Site? Split It Up  Expect search engines to max out at around 500 pages from any particular site  Increase representation by subdividing large sites logically into subdomains  Search engines will crawl each subsite to more depth  Here’s an example... Subdomains vs. Subdirectories Instead of Do this gold.ac.uk/science/ gold.ac.uk/english/ gold.ac.uk/admin/ science.gold.ac.uk english.gold.ac.uk admin.gold.ac.uk I Was Framed  Don't use them. Period.  If you do use them, search engines will have difficulty crawling your site. Dynamic Roadblocks  Dynamic delivery systems that use ? symbols in the URL string prevent search engines from getting to your pages  http://www.nike.com/ObjectBuilder/ObjectBuilder.iwx?ProcessN ame=IndexPage&Section_Id=17200&NewApplication=t  Eliminate the ? symbol, and your life will be rosy  Look for workarounds, such as Apache rewrite or Cold Fusion alternatives  Before you move to a dynamic delivery system, check out any potential problems. How Directories Work  Editors find sites, describe them, put them in a category  Site owners can also submit to be listed  A short description represents the entire web site  Usually has secondary results from a crawler-based search engine The Major Directories  Yahoo  The Open Directory  (Netscape, Lycos, AOL Search, others)  LookSmart  UK Plus  Snap Submitting To Directories  Directories probably won't find you or may list you badly unless you submit  Find the right category (more in a moment), then use Add URL link at top or bottom of page  Write down who submitted (and email address), when submitted, which category submitted to and other details  You’ll need this info for the inevitable resubmission attempt – it will save you time. Submitting To Directories  Take your time and submit to these right  Write 3 descriptions: 15, 20 and 25 words long, which incorporate your key terms  Search for the most important term you want to be found for and submit to first category that's listed which seems appropriate for your site  Be sure to note the contact name and email address you provided on the submit form  If you don't get in, keep trying Subdomain Advantage  Directories tend not to list subsections of a web site.  In contrast, they do tend to see subdomains as independent web sites deserving their own listings  So, another reason to go with subdomains over subdirectories Other Tips / Misc  Under represented?
