The only thing that comes to mind like this is in a different context. It's in site map files. There is a tag that looks like this
- Code: Select all
<priority>0.5000</priority>
But it's not web pages.
My view of this "feature" when I looked at it was that it was most likely ignored by anything that counts.
The Google tool that makes sitemaps is kinda hardwired to include these priority tags. It's not trivial to remove them.
Let us know when you find the web page equivalent.
