Best way to transform blog with visitors into community

Hi there :slight_smile:,

I got a blog that I have been keeping sort of on the backburner for the past 6 years, it's getting like 200 uniques a day and I am now ready to transform it into a community (actually thinking just a WP forum, no BP).

So I want all visitors that are currently landing on those articles on my blog (which are pretty bad tbh) to be sort of redirected to the forum so I have a chance to get them signed up into the forum, I don't want to redirect the articles to the forum for fear of losing the rankings and I don't just want to have a banner or sign up pop-up since I don't think it will convert that well...

What do you think is the best way to transform those visitors that land on crappy articles on my site into forum members without hurting my rankings etc...

Thanks :slight_smile:
