Potentially mis-leading text on fully-qualified URLs setting

[dleigh]

Hi,
In the advanced tab of the plugin is the option:

Add rel=alternate with fully qualified urls

After this is the comment:

This will make google happy and will increase size of html by a lot

This has been there for quite some time and I'd like to suggest that it be removed. SEO tools will flag the hreflang implementation as in error. According to this page: https://weglot.com/blog/self-referencing-hreflang/, relative URLs for the href tag of hreflang are incorrect and could affect whether a page is presented to a user because Google hasn't correctly interpreted the hreflang tag.

Additionally, "increase size of html by a log" is, of course, subjective, but my guess is that in most use cases, it's simply not true. Yes, the URL will be longer, but not necessarily by "a lot".

I'd change the verbiage to show what is produced when it's unchecked and what is produced when it's checked. I'd also mention that there can be an impact on SEO (for the users who care about that), if the URL is left as "relative".
