Currently I'm using the free cloudflare plan for my websites.
1. to get SSL
2. for DDOS protection
3. As A CDN network
Some people suggest that Cloudflare will have negative impact on my SEO because of loss in sitespeed (not for me so far) and the fact that spammy / adults sites might be running on the same cloudflare IP adress.
I was hoping to get some more opinions on this subject and advises on other options if necessary.
