Dear friends, Please suggest me that how to create sitemap.xml file for my 500 pages's site? I have been trying for long time but did not get it please help me guys. Thanks in advance for your suggestions
What type of cms are you running? Even if its "in house" so long as you have a database of all the content it wouldn't take long to adapt one to your needs. If you've been trying for a long time it might help if you explained why the others you have reviewed haven't met your requirements. 500 pages isn't many.
You should probably also state if you are only interested in free tools and services? (If 30 days fully functional trial would be enough for your needs, check my signature for XML sitemap tutorials.)
You can't do it manually for that you have to use any tools for site map. seo sitemap generator tools is the best way to solve your problem.
You should check and see if your host can install this http://code.google.com/p/googlesitemapgenerator/ . I have it installed on all my webservers and it will automatically generate google site maps for selected domains.
You can search for wonder web share sitemap generator which allows maximum pages to be included in the sitemap. Try to search for free sitemap generator which will really help you.
If have more than 500 links. Don't have sitemap generator services free. you must code in php & mysql
