Tagalys creates an XML file that contains all the product listing pages (PLP) created on Tagalys for which the 'Include in Sitemap' option is checked. The link to your dynamic XML file would be something like: https://api-r2.tagalys.com/v3/mpages/_sitemaps/E8744XXXXXXXA7342/1/sitemap.xml.
Make sure you follow the steps outlined on Sitemap Index format before including the XML file into your sitemap.
For example, your sitemap index (accessible at https://www.your-store.com/sitemap.xml) may look like this:
<sitemapindex xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"> <sitemap> <loc>https://www.your-store.com/sitemap-categories.xml</loc> </sitemap> <sitemap> <loc>https://www.your-store.com/sitemap-products.xml</loc> </sitemap> <sitemap> <loc>https://www.your-store.com/sitemap-pages.xml</loc> </sitemap> <sitemap> <loc>https://www.your-store.com/sitemap-tagalys.xml</loc> </sitemap> </sitemapindex>
You can setup a cron job to download this file to your webroot folder once a day and include the file in your sitemap index as described above. Submit your sitemap index to search engines for indexing.
