"CloudFlare Pro"...my host wants me to use it?

I just signed up for new hosting and my host recommends "CloudFlare Pro". I'd like an opinion on if this is a good idea for me for wordpress blogging/autoblogging.

Is there any problem with serp's, or anthing else to watch out for.

I'm not sure yet cause I'm waiting for an answer from them, but do I have to transfer my domain to them?

Just planning to use them for a few domains/10 or so subdomains with adsense blogs.

Advise please....should I agree to CloudFlare Pro? Thanks.

Its a content delivery service only, why did your host ask you to use it? Are your websites taking up too much resources? No i dun think u have to transfer your domain only your pages will send to it to be stored.

I'm not sure why my host is recommending that I use ClouldFlare, but there is no charge for it. I've nothing hosted there so I'm not causing any bandwidth problems.
I see the claims of faster page loading, etc., but I wonder about any issues I may run into using it. I can't find many complaints but I did see someone mention problems with subdomains and cPanel. This was a few months ago, so maybe there's no issue now.
Thanks for your response!

Nar if ur cpu resource doesn't go over the limit and your bandwidth is used within the limits there isn't a need for a CDN. CDN is mainly used for sites with a lot of content and access to those sites slow down when too many ppl visit or there is too much information downloaded.
