I've already install VBSEO for my forum VBB. But to make Google understand all the site,we need sitemap.xml to help google. I do not know how to creat sitemap.xml for my site and which is product can be use for automatic creat sitemap after we have new topic or post. Is VBSEO can solve this problem, and how can it solve. You are very kind to show me clearly. Thank kiu. Beside, the file robots.txt of VBB forum is the same with other platforms. Is it right?
