The simplest version of Sitemap file contains only text. http://www.webpagemistakes.ca/create- sitemap-or-html-site-map/ http://www.webpagemistakes.ca/create- sitemap-or-html-site-map/ 28

31 Creating a robots.txt File Bots Also known as crawlers, they are programs that search engines use to index Web pages. Influences which pages are indexed. S.E. look for files named robots.txt Should be located in the root folder of your web site. 30

32 The "User-Agent" part specifies which search engines you are giving the directions to. Using the asterisk means you are giving directions to ALL search engines. The "disallow" part specifies what content you don't want the search engines to index. If you don't want to block the search engines from any area of your web site, you simply leave this area blank. For most small web sites, those two simple lines are all you really need. 31

33 You can give some instructions about which content to avoid. A good example of this would be a site that has printer- friendly versions of all of their content housed in a folder called "print-ready." There's no reason for the search engines to index both forms of the content, so it's a good idea to go ahead and block the engines from indexing the printer-friendly versions. In this case, you'd leave the "user-agent" section alone, but would add the print-ready folder to the "disallow" line. That robots.txt file would look like this: User-Agent: * Disallow: /print-ready/ 32

34 A word of warning. While some sites will tell you to use robots.txt to block premium content you don't want people to see, this isn't a good idea. While most search engines will respect your robots.txt file and ignore the content you want to have blocked, a far safer option is to hide that premium content behind a login. Requiring a username and password to access the content you want hidden from the public will do a much more effective job of keeping both search engines and people out. 33

35 Previewing and Finalizing Your Site Useful to give documents final check from bot point of view Helps identify missing or hidden content Ensures that pages are ready for indexing Can install free programs to view only text Can approximate view by changing browser settings 34
