This plugin will generate a special XML sitemap which will help search engines like Google, Bing, Yahoo and Ask.com to better index your blog. With such a sitemap, it’s much easier for the crawlers to see the complete structure of your site and retrieve it more efficiently. The plugin supports all kinds of WordPress generated pages as well as custom URLs. Additionally it notifies all major search engines every time you create a post about the new content.
Supported since over 9 years and rated as the best WordPress plugin, it will do exactly what it’s supposed to do – providing a complete XML sitemap for search engines. It will not break your site, slow it down or annoy you. Guaranteed!
If you like the plugin, feel free to rate it (on the right side of this page) or donate via PayPal. I’m gladly supporting this plugin since over 9 years! Thanks a lot!

License
Good news, this plugin is free for everyone! Since it’s released under the GPL, you can use it free of charge on your personal or commercial blog. But if you enjoy this plugin, you can thank me and leave a small donation for the time I’ve spent writing and supporting this plugin. And I really don’t want to know how many hours of my life this plugin has already eaten 
Translations
The plugin comes with various translations, please refer to the WordPress Codex for more information about activating the translation. If you want to help to translate the plugin to your language, please have a look at the sitemap.pot file which contains all definitions and may be used with a gettext editor like Poedit (Windows).
Install the plugin like you always install plugins, either by uploading it via FTP or by using the “Add Plugin” function of WordPress.
Activate the plugin at the plugin administration page
If you want: Open the plugin configuration page, which is located under Settings -> XML-Sitemap and customize settings like priorities and change frequencies.
The plugin will automatically update your sitemap of you publish a post, so there is nothing more to do
Where can I find the options page of the plugin?
It is under Settings > XML Sitemap. I know nowadays many plugins add top-level menu items, but in most of the cases it is just not necessary. I’ve seen WP installations which looked like an Internet Explorer ten years ago with 20 toolbars installed.
Do I have to create a sitemap.xml and sitemap.xml.gz by myself?
Not anymore. Since version 4, these files are dynamically generated. There must be no sitemap.xml or sitemap.xml.gz in your blog directory anymore! The plugin will try to rename them to sitemap.xml.bak if they still exists.
Does this plugin use static files or “I can’t find the sitemap.xml file!”
Not anymore. Since version 4, these files are dynamically generated just like any other WordPress content.
There are no comments yet (or I’ve disabled them) and all my postings have a priority of zero!
Please disable automatic priority calculation and define a static priority for posts.
So many configuration options… Do I need to change them?
No, only if you want to. Default values are ok for most sites.
Does this plugin work with all WordPress versions?
This version works with WordPress 3.3 and better. If you’re using an older version, please check the Google Sitemaps Plugin Homepage for the legacy releases. There is a working release for every WordPress version since 1.5, but you really should consider updating your WordPress installation!
My question isn’t answered here
Most of the plugin options are described at the plugin homepage as well as the dedicated Google Sitemaps FAQ.
My question isn’t even answered there
Please post your question at the WordPress support forum and tag your post with “google-sitemap-generator”.
What’s new in the latest version?
The changelog is maintained here
Why is the changelog on a separate page and not here?
The WordPress.org repository is just another place to download this plugin. I don’t want to maintain too many pages with the same content. Thank you for your understanding!
You can always find the changelog on the plugin website, since I don’t like to maintain the same content on different pages. Thank you for your understanding!
