Baidu official confirms the link of plain text. URL will be grabbed by Baidu. Baidu crawler will grab the pure text link on the network. Here's a reply from Baidu webmaster club Lee.
1, the text links the URL address, and Baidu will find that he is a URL address and grabbed it through the address to the corresponding URL address.
2, whether we should transmit weight to the link, the only criterion is whether this link is user or, the other website really recommends your website, this recommendation is valuable to users.
Note: plain text link is also a URL that removes hyperlinks. Most articles will be removed by hyperlinks, which is undoubtedly good news, but it is not sure whether to transmit weights.
