One n00b question — what is the advantage of Geositemap and can you please refer a resource that I can use to understand Geositemaps. Hi, this come in time to me. Main Menu. Perishable Press. About the Author. Passionate about free and open Web. Banhammer : Protect your WordPress site against threats. Nice article, BTW. Hello Thank you for the great post. Keep up the good work.!
Great article, explains everything really well — especially the roll your own section. Thanks for sharing with us. Keep the good job. Comments are closed for this post. Something to add? Parent tag for each URL entry. The remaining tags are children of this tag. URL of the page. This URL must begin with the protocol such as http and end with a trailing slash, if your web server requires it.
This value must be less than 2, characters. The date of last modification of the file. This date should be in W3C Datetime format. Note that this tag is separate from the If-Modified-Since header the server can return, and search engines may use the information from both sources differently. How frequently the page is likely to change. This value provides general information to search engines and may not correlate exactly to how often they crawl the page.
Valid values are:. The value "always" should be used to describe documents that change each time they are accessed. The value "never" should be used to describe archived URLs. Please note that the value of this tag is considered a hint and not a command. Even though search engine crawlers may consider this information when making decisions, they may crawl pages marked "hourly" less frequently than that, and they may crawl pages marked "yearly" more frequently than that.
Crawlers may periodically crawl pages marked "never" so that they can handle unexpected changes to those pages. Valid values range from 0. This value does not affect how your pages are compared to pages on other sites—it only lets the search engines know which pages you deem most important for the crawlers.
Please note that the priority you assign to a page is not likely to influence the position of your URLs in a search engine's result pages. Search engines may use this information when selecting between URLs on the same site, so you can use this tag to increase the likelihood that your most important pages are present in a search index.
Also, please note that assigning a high priority to all of the URLs on your site is not likely to help you. Since the priority is relative, it is only used to select between URLs on your site.
Your Sitemap file must be UTF-8 encoded you can generally do this when you save the file. As with all XML files, any data values including URLs must use entity escape codes for the characters listed in the table below.
However, if you are using any sort of script, tool, or log file to generate your URLs anything except typing them in by hand , this is usually already done for you. The following example shows a Sitemap in XML format. The Sitemap in the example contains a small number of URLs, each using a different set of optional parameters. You can provide multiple Sitemap files, but each Sitemap file that you provide must have no more than 50, URLs and must be no larger than 50MB 52,, bytes.
If you would like, you may compress your Sitemap files using gzip to reduce your bandwidth requirement; however the sitemap file once uncompressed must be no larger than 50MB. If you want to list more than 50, URLs, you must create multiple Sitemap files. If you do provide multiple Sitemaps, you should then list each Sitemap file in a Sitemap index file. Sitemap index files may not list more than 50, Sitemaps and must be no larger than 50MB 52,, bytes and can be compressed.
You can have more than one Sitemap index file. Note: A Sitemap index file can only specify Sitemaps that are found on the same site as the Sitemap index file. Identifies the time that the corresponding Sitemap file was modified. It does not correspond to the time that any of the pages listed in that Sitemap were changed.
The value for the lastmod tag should be in W3C Datetime format. By providing the last modification timestamp, you enable search engine crawlers to retrieve only a subset of the Sitemaps in the index i. This incremental Sitemap fetching mechanism allows for the rapid discovery of new URLs on very large sites. The Sitemap protocol enables you to provide details about your pages to search engines, and we encourage its use since you can provide additional information about site pages beyond just the URLs.
However, in addition to the XML protocol, we support RSS feeds and text files, which provide more limited information. Generally, you would use this format only if your site already has a syndication feed. For details, see the Google Developers Site Policies. Documentation Not much time? Beginner SEO Get started.
