Sitemap for search engines
For basic search engine optimization it's good to have a sitemap.xml file, which contains machine-readable information about all the pages and the structure of your site.
The syntax for such a sitmap.xml file is fairly simple. You can find all about it on http://www.sitemaps.org/
Because you probably don't want to generate that file by hand, I've created a little template for you, which automatically indexes your entire site and generates a sitemap.xml for you:
<?php $ignore = array('sitemap', 'error'); // send the right header header('Content-type: text/xml; charset="utf-8"'); // echo the doctype echo '<?xml version="1.0" encoding="utf-8"?>'; ?> <urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <?php foreach($pages->index() as $p): ?> <?php if(in_array($p->uri(), $ignore)) continue ?> <url> <loc><?php echo html($p->url()) ?></loc> <lastmod><?php echo $p->modified('c') ?></lastmod> <priority><?php echo ($p->isHomePage()) ? 1 : number_format(0.5/$p->depth(), 1) ?></priority> </url> <?php endforeach ?> </urlset>
Copy the entire code from above and put it in your
site/templates directory in a new file called
Go to your content folder and create a new invisible folder called
sitemap and also add a text file to it called
xmlsitemap.txt (and don't forget to add the language extensions if you are on a multi-language site).
You should now be able to visit the sitemap of your Kirby site by browsing
http://yourdomain.com/sitemap.xml (Kirby ignores the extension, so you can use both)
To exclude certain subpages of your site, you can add their URI to the
$ignore array. I've already done that for the sitemap page itself and also for the error page.
$ignore = array('sitemap', 'error');
If you are using the HTML cache, you should make sure to avoid caching of the sitemap file. Go to
site/config/config.php and change the cache settings like this:
This will make sure that your sitemap file is always served as proper XML.
The sitemap template will automatically try to create priorites for each page, by using the
->depth() attribute. The depth attribute is a simple number, which indicates how deep the page is nested. Main pages have a depth of 1, subpages of main pages have a depth of 2, etc.
The home page will automatically get a priority of 1. You can easily change priorities or remove them entirely if you prefer.
Submitting your sitemap to a search engine
To let your favorite search engines know about your brand new sitemap, please read the instructions on sitemap.org: http://www.sitemaps.org/protocol.html#informing
I'm always looking for contributers, to improve Kirby's extensions. I'm not a specialist with Search Engine Optimization, so if you have ideas how to improve the xmlsitemap.php template or any other extension, just let me know!!
