- This plugin dynamically creates an XML feed that complies with the XML Sitemap protocol. There are no options to be set and the feed becomes instantly available after activation on yourblogurl.tld/sitemap.xml (or yourblogurl.tld/index.php?feed=sitemap.xml if you do not use a fancy permalink structure) ready for indexing by search engines like Google, Yahoo, MSN, Ask.com and others.

- An entry `Sitemap: http://yourblogurl.tld/sitemap.xml` is added to the (by WordPress dynamically created) robots.txt on yourblogurl.tld/robots.txt to tell search engines where to find your XML Sitemap.

- **Q: How are the values for priority and changefreq calculated?**
70
-
71
- **A:** The front page has a fixed priority of 100% (1.0), pages are always 50% (0.5) and new posts have a default priority of 70% (0.7) but can vary between 10% (0.1) and 90% (0.9) depending on comments and post age. The cangefreq of the frontpage is set to daily, monthly for pages and either monthly or weekly for posts depending on comments.
72
 
73
  Dynamic pages like category pages, tag pages and archive pages are not listed in the XML Sitemap.
74
 
75
- **Q: Can I manipulate values for priority and changefreq?**
 
 
76
 
77
- **A:** Yes and No. Since this plugin has no options page there is no way (yet) to manually set the priority of urls in the sitemap. The priority of the frontpage is fixed to 100% (1.0), all other pages are fixed to 50% (0.5) and new posts are always 70% (0.7). Since version 2.0 there is automatic post priority calculation based on post age and comment activity, that can either make post priority go to 90% (0.9) for fairly recent posts with many comments or 10% (0.1) for very old posts with no comments.
78
 
79
- This feature can be used to your advantage: by resaving your most important older posts from time to time, keeping the lastmod date fairly recent, you can ensure a priority of at least 70% (0.7) for those urls. And if you have comments on on those pages, the priority will even go up to 90% (0.9).
80
 
81
- If you cannot live with these rules, edit the values `$post_priority`, `$minpost_priority`, `$maxpost_priority`, `$page_priority`, `$frontpage_priority` in xml-sitemap-feed/template-xml.php
82
 
83
- **Q: Do I need to submit the sitemap to search engines?**
84
 
85
- **A:** No. In normal circumstances, your site will be indexed by the major search engines before you know it. The search engines will be looking for a robots.txt file and (with this plugin activated) find a pointer in it to the XML Sitemap on your blog. The search engines will return on a regular basis to see if your site has updates.

- **A:** No. While other XML Sitemap plugins provide pinging to some search engines upon each post edit or publication, this plugin does not. There are two reasons for that:

107
- **Q: Do I need to change my robots.txt?**
108
 
109
- **A:** That depends. If you have no physical robots.txt file in your site root, the new sitemap url will be automatically added to your dynamic robots.txt when plugin actived. But if you use a static robots.txt file in your website root, you will need to open it in a text editor and add a line like `Sitemap: http://yourblogurl.tld/sitemap.xml` (adapt to your site url) to make search engines find your XML Sitemap.

113
- **Q: My WordPress powered blog is installed in a subdirectory. Does that change anything?**
114
 
115
- **A:** That depends on where the index.php and .htaccess of your installation resides. If it is in the root, meaning WP is installed in a subdir but the blog is accessible from your domain root, you do not have to do anything. It should work out of the box. However, if the index.php is (e.g. still with your wp-config.php and all other WP files) in a subdir, meaning your blog is only accessible via that subdir, you need to manage your own robots.txt file in your domain root. It _has_ to be in the root (!) and needs a line starting with `Sitemap:` followed by the full URL to the sitemap feed provided by XML Sitemap Feed plugin. Like:
 
 
116
  `
117
  Sitemap: http://yourblogurl.tld/subdir/sitemap.xml
118
  `
119

  If you already have a robots.txt file with a line like that, you might want to read more about creating an XML Sitemap Index on [sitemaps.org](http://www.sitemaps.org/protocol.php#index).

122
- **Q: Do I need to use a fancy Permalink structure?**
123
 
124
- **A:** No. While I would advise you to use any one of the nicer Permalink structures, you might not be able to (or don't want to) do that. If so, you can still use this plugin:
125
 
126
- Check to see if the URL yourblogurl.tld/?feed=sitemap.xml (notice the **?feed=**!) does produce a feed. Now manually upload your own robots.txt file to your website root containing:
127
  `
128
- Sitemap: http://yourblogurl.tld/?feed=sitemap.xml

  User-agent: *

137
- **Q: Can I change the sitemap name/URL?**
138
 
139
- **A:** No. If you have fancy URL's turned ON in WordPress (Permalinks), the sitemap url that you manually submit to Google (if you are impatient) should be `yourblogurl.tld/sitemap.xml` but if you have the Default option set the feed is only available via `yourblogurl.tld/?feed=sitemap.xml` (notice the *?feed=*).
140
 
141
- **Q: Where can I customize the xml output?**
142
 
143
- **A:** You may edit the XML output in `xml-sitemap-feed/feed-xml.php` but be carefull not to break Sitemap protocol comliance. Read more on [Sitemaps XML format](http://www.sitemaps.org/protocol.php).

147
- **Q: I get a 404 page instead of both sitemap.xml and robots.txt!**
148
 
149
- **A:** There are plugins like Event Calendar (at least v.3.2.beta2) known to mess with rewrite rules, causing problems with WordPress internal feeds and robots.txt generation and thus conflict with the XML Sitemap Feed plugin. Deactivate all plugins and see if you get a basic robots.txt file showing:

+ But if you have a server without rewrite rules, use your blog without fancy URLs or have it installed in a subdirectory, read **Do I need to change my robots.txt** for more instructions.
89
 
90
+ = Does this plugin ping search engines? =
91
 
92
+ No. While other XML Sitemap plugins provide pinging to some search engines upon each post edit or publication, this plugin does not. There are two reasons for that:
93
 
94
  1. WordPress has a built-in pinging feature. Go in your WP Admin section to Settings > Writing and make sure that the text area under **Update services** contains at least
95
  `
101
 
102
  You can always take a [Google Webmaster Tools account](https://www.google.com/webmasters/tools/) which will tell you many interesting things about your website, search terms and your visitors. Try it!
103
 
104
+ = I see no sitemap.xml file in my server space! =
105
 
106
+ The sitemap is dynamically generated just like a feed. There is no actual file created.
107
 
108
+ = Do I need to change my robots.txt? =
109
 
110
+ That depends. In normal circumstances, if you have no physical robots.txt file in your site root, the new sitemap url will be automatically added to the dynamic robots.txt that is generated by WordPress. But in some cases this might not be the case.
111
 
112
+ If you use a static robots.txt file in your website root, you will need to open it in a text editor and add a line like `Sitemap: http://yourblogurl.tld/sitemap.xml` (adapt to your site url) to make search engines find your XML Sitemap.
113
 
114
+ Or if you have WP installed in a subdirectory, on a server without rewrite_rules or if you do not use fancy URLs in your Permalink structure settings. In these cases, WordPress will need a little help in getting ready for XML Sitemap indexing. Read on in the **WordPress** section for more.
115
 
116
+ = My WordPress powered blog is installed in a subdirectory. Does that change anything? =
117
+
118
+ That depends on where the index.php and .htaccess of your installation resides. If it is in the root, meaning WP is installed in a subdir but the blog is accessible from your domain root, you do not have to do anything. It should work out of the box. However, if the index.php is (e.g. still with your wp-config.php and all other WP files) in a subdir, meaning your blog is only accessible via that subdir, you need to manage your own robots.txt file in your domain root. It _has_ to be in the root (!) and needs a line starting with `Sitemap:` followed by the full URL to the sitemap feed provided by XML Sitemap Feed plugin. Like:
119
  `
120
  Sitemap: http://yourblogurl.tld/subdir/sitemap.xml
121
  `
122
 
123
  If you already have a robots.txt file with a line like that, you might want to read more about creating an XML Sitemap Index on [sitemaps.org](http://www.sitemaps.org/protocol.php#index).
124
 
125
+ = Do I need to use a fancy Permalink structure? =
126
 
127
+ No. While I would advise you to use any one of the nicer Permalink structures, you might not be able to (or don't want to) do that. If so, you can still use this plugin:
128
 
129
+ Check to see if the URL yourblogurl.tld/index.php?sitemap=1 (notice the **?sitemap=** !) does produce a feed. Now manually upload your own robots.txt file to your website root containing:
130
  `
131
+ Sitemap: http://yourblogurl.tld/index.php?sitemap=1
132
 
133
  User-agent: *
134
  Allow: /
135
  `
136
+ You can also choose to notify major search engines of your new XML sitemap manually. Start with getting a [Google Webmaster Tools account](https://www.google.com/webmasters/tools/) or head over to [XML-Sitemaps.com](http://www.xml-sitemaps.com/validate-xml-sitemap.html) and enter your sites sitemap URL.
 
 
137
 
138
+ = Can I change the sitemap name/URL? =
139
 
140
+ No. If you have fancy URL's turned ON in WordPress (Permalinks), the sitemap url that you manually submit to Google (if you are impatient) should be `yourblogurl.tld/sitemap.xml` but if you have the Default option set the feed is only available via `yourblogurl.tld/?sitemap=1`.
141
 
142
+ = Where can I customize the xml output? =
143
 
144
+ You may edit the XML output in `xml-sitemap-feed/sitemap.xml.php` but be carefull not to break Sitemap protocol comliance. Read more on [Sitemaps XML format](http://www.sitemaps.org/protocol.php).
145
 
146
+ The stylesheet (to make the sitemap human readable) can be edited in `xml-sitemap-feed/sitemap.xsl.php`.
147
 
148
+ = I get a 404 page instead of both sitemap.xml and robots.txt! =
149
 
150
+ There are plugins like Event Calendar (at least v.3.2.beta2) known to mess with rewrite rules, causing problems with WordPress internal feeds and robots.txt generation and thus conflict with the XML Sitemap Feed plugin. Deactivate all plugins and see if you get a basic robots.txt file showing:
151
  `
152
  User-agent: *
153
  Disallow:
154
  `
155
  Reactivate your plugins one by one to find out which one is causing the problem. Then report the bug to the plugin developer.
156
 
157
+ = I get a 404 page instead of robots.txt while sitemap.xml works fine! =
158
 
159
+ There is a know issue with WordPress (at least up to 2.8) not generating a robots.txt when there are _no posts_ with _published_ status. If you use WordPress as a CMS with only _pages_, this will affect you.
160
 
161
  To get around this, you might either at least write one post and give it _Private_ status or alternatively create your own robots.txt file containing:
162
  `
167
  `
168
  and upload it to your web root...
169
 
170
+ = Can I do a Network Activate with this plugin on WP3.0 MS / WPMU ? =

+
172
+ Yes.
