A Sitemap is an index of all your pages on your website or blog. Typically a single XML file, the Sitemap includes a list of the URLs of all pages on your website. Irrelevant if you are using WordPress or not, a Sitemap is a must have for every website or blog, especially if you want your website to be crawled properly by search engines and rank well in search engine search results. There are many different types of Sitemaps, each of which having its own use. In this article we will give you an overview of what sitemap are, why they are used and why it is important to have them.

XML sitemap for search engines

Google, Yahoo and Microsoft search engines always look for a sitemap.xml or sitemap.xml.gz (compressed version of the sitemap XML file) when crawling your website. Unless advised otherwise, sitemaps should always be in the root of a website, e.g. Sitemaps are a way of telling search engines such as Google about all the pages on your website that the search engine spiders might have not discovered via other means. Below is a typical URL entry in an XML Sitemap:


As seen in the above example, for each URL listed in a website Sitemap, there are additional attributes you can add apart from the actual URL. The optional attributes are:

  • <lastmod>; the date of the last modification of this file or page. The format of the date should be in W3C Datetime format, which is yyyy-mm-dd.
  • <changefreq>; how frequently this file or page is likely to change. The options for such attributes are always, hourly, daily, weekly, monthly, yearly, never.
  • <priority>; how important this URL is in relative to other URL’s on the same website. Valid value ranges from 0.0 to 1.0. If not specified, the default assigned value is always of 0.5.
