Hello, My page last days have big DDOS attack I see CloudFlare can help for protect website of ddos attack but i see also some users say CloudFlare can reduce your PR, SERP anyone has exp with this ? Thanks.
I don't know if it affects your PR but I do use CloudFlare and I'm a huge fan of it. I normally opt for the $20 a month plan for the increased speed And security options
I would suggest reading this: https://forums.digitalpoint.com/threads/adsense-cloudflare-not-a-good-mix-unfortunately.2632911/ It will give you an idea of some potentially problems. And also searching Google/Bing regarding CloudFlare and GoogleBot crawling problems. CloufFlare won't reduce your PR or position, but if there are crawling problems it will (potentially) get you de-indexed (temporarily) until the issues have been resolved. Have you considered a host that provides DDOS mitigation without the use of CloudFlare?
