It would be nice if there was the ability to have the plugin update the “UpdatedOnUTC” record in the products that are in each template.
The reason I say this is so that the sitemap.xml file will flag google to update the product/category listing to show the new data that SmartSEO produces. I assume that Google won’t go through the re-crawl process for items that don’t have a recent update/change date.
Am I wrong in this? Is there another way I can “force” google to do a complete re-index?
I am not sure if Google rely too much at the sitemap. I don't really know exactly what their algorithm is but I believe they re-index the whole website every 3-4 days based on my observation in our website.
I am not sure if it is correct to change the updated time of the products from the Smart SEO plugin as we are actually not changing the actual products.
I think a better solution would be to have a setting for the Sitemap to show a specific updated time for everything and not rely on the updated time. This way you can "force" the whole website to be re-indexed assuming google uses that information to re-index the site of course (which I really doubt).
