= Privacy / GDPR =

This plugin does not collect any user or visitor data nor set browser cookies. Using this plugin should not impact your site privacy policy in any way.

**Data that is published**

An XML Sitemap index, referencing other sitemaps containing your web site's public post URLs of selected post types that are already public, along with their last modification date and associated image URLs, and any selected public archive URLs.
An author sitemap can be included, which will contain links to author archive pages. These urls contain author/user slugs, and the author archives can contain author bio information. If you wish to keep this out of public domain, then deactivate the author sitemap and use an SEO plugin to add noindex headers to the respective archive pages.

A Google News Sitemap containing your web site's public and recent (last 48 hours) URLs of selected news post type, along with their publication time stamp and associated image URL.

**Data that is transmitted**

when a connection between your site and Google Search Console is configured in this plugin, the sitemap index and google news sitemap can be submitted to Google. No data is transmitted to any third party.

= Contribute =

If you're happy with this plugin as it is, please consider writing a quick [rating](https://wordpress.org/support/plugin/xml-sitemap-feed/reviews/#new-post) or helping other users out on the [support forum](https://wordpress.org/support/plugin/xml-sitemap-feed).

If you wish to help build this plugin, you're very welcome to [translate it into your language](https://translate.wordpress.org/projects/wp-plugins/xml-sitemap-feed/) or contribute code on [Github](https://github.com/RavanH/xml-sitemap-feed/).

= Credits =

XML Sitemap Feed was originally based on the discontinued plugin Standard XML Sitemap Generator by Patrick Chia. Since then, it has been completely rewritten and extended in many ways.

**NOTES:**

1. If you _do not use fancy URL's_ or you have WordPress site running in a _subdirectory_, a dynamic **robots.txt will NOT be generated**.

2. On large sites, it is advised to use a good caching plugin to improve your site _and_ sitemap performance.


== Installation ==

= Wordpress =

**I.** If you have been using another XML Sitemap plugin before, check your site root and remove any created sitemap.xml, sitemap-news.xml and (if you're not managing this one manually) robots.txt files that remained there.

**II.** Install plugin by:

Quick installation via **[Covered Web Services](http://coveredwebservices.com/wp-plugin-install/?plugin=xml-sitemap-feed)** !

 &hellip; OR &hellip;

Search for "xml sitemap feed" and install with that slick **Plugins > Add New** admin page.

 &hellip; OR &hellip;

Follow these steps:

1. Download archive.

2. Upload the zip file via the Plugins > Add New > Upload page &hellip; OR &hellip; unpack and upload with your favourite FTP client to the /plugins/ folder.

**III.** Activate the plugin on the Plugins page.

Done! Check your sparkling new XML Sitemap by visiting yourblogurl.tld/sitemap.xml (adapted to your domain name of course) with a browser or any online XML Sitemap validator. You might also want to check if the sitemap is listed in your yourblogurl.tld/robots.txt file.

= WordPress 3+ in Multi Site mode =

Same as above but do a **Network Activate** to make a XML sitemap available for each site on your network.

Installed alongside [WordPress MU Sitewide Tags Pages](http://wordpress.org/plugins/wordpress-mu-sitewide-tags/), XML Sitemap Feed will **not** create a sitemap.xml nor change robots.txt for any **tag blogs**. This is done deliberately because they would be full of links outside the tags blogs own domain and subsequently ignored (or worse: penalised) by Google.

= Uninstallation =

Upon uninstalling the plugin from the Admin > Plugins page, plugin options and meta data will be cleared from the database. See notes in the uninstall.php file.

On multisite, the uninstall.php loops through all sites in the network to perform the uninstallation process for each site. However, on large networks it *only* does this when `define('XMLSF_MULTISITE_UNINSTALL', true);` is explicitly set in wp-config.php.


== Frequently Asked Questions ==

Please read more on [FAQ's and Troubleshooting](https://premium.status301.com/knowledge-base/xml-sitemap-google-news/faqs-and-troubleshooting/)
