XF 1.2 Do Thread Prefixes Affect SEO?

[DRE]

Does setting a thread prefix apply a keyword for the thread in the metadata etc?

Yes, it appears in the meta title of the actual index file, so whatever word is before the thread will be picked up by search engines.

If you want proof, try sharing your thread with the prefix, the social network will pick up the prefix as well as the thread title.

My clan forum has "PSN" "Xbox Live" and "PC" before every thread, and every time I share it on facebook or another major social network, the snippet picks up the "PSN/Xbox Live/PC" prefix.

Some members of the Staff at my forum complained that with prefixes SEO was worse...
