It is useful to index your pages quickly .It is a file that you can submit to search engines to get your pages indexed.
yes you need a sitemap try the gool sitemap generator http://code.google.com/p/googlesitemapgenerator/
A site map is most definitely always suggested. Although your site will get crawled it will be much more efficient with a site map.
couple of days after i created and submitted my site map to google it started giving more results about inner pages in google search
Sitemap is a know good practice and it can get the following benefits : 1. Let know to the google, yahoo and others boots the page structure of your site. 2. I can very helpful when your site has deep pages (more than 3 clicks from home). 3. Finally you can assign an relative importance at page level by setting the piority tag. Always we use sitemaps and recommend to use it Hope it help
Finally you can learn at google webmaster tools how to build a sitemap, I paste a sample here File Format xml. <?xml version="1.0" encoding="UTF-8"?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.google.com/schemas/sitemap/0.84 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd"> <url><loc>http://www.yourdomain/</loc><lastmod>2010-08-31</lastmod><changefreq>weekly</changefreq><priority>1</priority></url> <url><loc>http://www.yourdomain/page1.html</loc><lastmod>2010-08-31</lastmod><changefreq>weekly</changefreq><priority>0.8</priority></url> <url><loc>http://www.yourdomain/page2.html</loc><lastmod>2010-08-31</lastmod><changefreq>weekly</changefreq><priority>0.8</priority></url> <url><loc>http://www.yourdomain/page3.html</loc><lastmod>2010-12-10</lastmod><changefreq>weekly</changefreq><priority>0.5</priority></url> </urlset>
Yes, it is useful to submit a sitemap especially if your site has 100s of pages with deep internal linking. Also, you can indicate to SEs the priority of individual webpages.
yes sitemap is necessary i have a business directory top uk directory dot co dot uk and i update my sitemap every 3 months how often you need to create one? how many links in one sitemap ?
well if you are interested in the fast indexing of all your pages, actually this depend on the pages of websites usually websites with thousands of pages need to submit sitemap rather then using google add url option
I think it's not needed. If google isn't spidering all of your pages, you should redesign the link structure of your website. This way, google AND visitors will find all the pages.
Is there a difference if i put in sitemap url: http:// www.mydomain/page1.html or http:// mydomain/page1.html ? Its possible the google or yahoo bots consider that an error?
A sitemap tells Googlebot where all the pages in your site are. It's basically a giant internal backlinking page to make sure your whole site gets indexed. If you're building links to important pages, they will get indexed just fine without a site map. Here's my rule: If I can install a Wordpress Plugin and automate the sitemap process, I'll do it. Otherwise, it's not worth the time...
Sitemaps offer the opportunity to inform search engines immediately about any changes on your site. Of course, you cannot expect that search engines will rush right away to index your changed pages but certainly the changes will be indexed faster, compared to when you don't have a sitemap.
I see that google find my pages, every day finds some other secondary pages when i search and never finds my main page(index.html), why?
