I have a PHPBB3 forum. I have had success with SEO by adding a few mods to my site. The xml sitemap generator has been helpful, as has changing the title and description of forum posts. 2 mods I am toying with the idea of installing: 1. Canonical URLs. Seems like a good mod, easy and trouble free. But I'm wondering how effective using canonical url tags is for SEO. Anyone have experience with before and after? 2. Static URLs. This mod seems like a nightmare... lots of problems. Seems like more of a headache to install than not. Anyone have an opinion on this?
It will be better to answer you which mods do you want to add - like SEO, Advertisement Management etc. In my forum I made this but not in higher version.
