“WordPress is inserting ‘href.li…’ at the beginning of links, on my private blog. Why?”
If you have a private blog, WordPress.com sometimes inserts this into links automatically. It sends the visitor to the link but hides the referrer (your website). This means you can link out from your private blog but other website owners won’t know where the visitors are coming from. This helps to keep even the existence of your private blog unknown.
If you prefer, you can switch off this feature by going to Settings > Reading and checking the box next to “I would like my links to be public, without being passed through a referrer hider.” Don’t forget to Save Changes :-)
All the best,
