Should I create one website or many?
po: In my opinion, it depends on the crossover of users. If the information is clearly not useful to different users its ok to put them on different sites. If one site is fastestanimals.com and one is baseballplayers.com then it might be better to create separate sites to cater to the audiences separately.I sometimes wonder why serverfault, poweruser and stackoverflow are on different domains as I think in many cases its the same user community. nobody is going to search three times in each service.I think you're lining yourself up to be spread too thin. Creating infographics is time consuming and I would suspect that it would be better to focus on one topic and really nail that first before thinking about spreading out across multiple topics. Can you really create enough infographics on one topic often enough to have users coming back to your site over and over? What about multiple topics?I'll admit that I don't know much about the SEO aspects of this though.
