Another goody found in the refreshed Bing Webmaster Guidelines is that Bing currently bolsters rel="sponsored" and rel="ugc" qualities on your connections. This is notwithstanding Bing supporting the rel="nofollow" interface property, which we realize it has upheld since its presentation more than ten years back. 

New connection traits. These two new connection qualities were presented by Google last September. These are the way these properties are dealt with. Bing wrote in the rules "put forth a sensible attempt to guarantee that any paid or promotion joins on your site use rel="nofollow" or rel="sponsored" or rel="ugc" credit to keep the connections from being trailed by a crawler and from conceivably affecting pursuit rankings." 

rel="sponsored": The new supported credit can be utilized to distinguish joins on your site that were made as a feature of ads, sponsorships or other remuneration understandings. 

rel="ugc": The ugc characteristic worth is suggested for joins inside client created content, for example, remarks and discussion posts. 

A Bing representative affirmed with Search Engine Land that these connection qualities are treated as clues, not really orders. So in fact Bing can choose to in any case follow these connections in the event that it esteemed vital. The rel supported and rel ugc characteristics are being checked by Bing and are "not as solid of a sign for Bing," we were told. This may change dependent on appropriation rates after some time. 

Why we give it a second thought. This implies in the event that you do choose to add these credits to your site, Bing will likewise consider. Bing's rules says you can utilize every one of the three, the rel="nofollow" or rel="sponsored" or rel="ugc" properties, to "keep the connections from being trailed by a crawler and from possibly affecting hunt rankings."
