This restriction is there just for the last 2 hours. You could do 5 analysis without any account before. The reason is that I got a huge traffic from HackerNews and the service was not prepared for such a big load and were (are) there many technical issues. I know, it is my bad but I really did not expect that people will love this service (concept) so much that it will go on #1 page on Hackernews.
Makes sense. Would have been nice to put a note about that. Something like 'sorry, due to really high usage, you have to sign up for an account.' Just letting people know. Good luck!
> Why to sign up? As a registered user you will be able to perform more searches for free. No spam.
Making you sign up is not unreasonable. But I find this text annoying. Yes I can perform "more" searches for free if I sign up, meaning more than zero.
right, a result of the quick change over to help not kill the servers or their/his wallet.. if you do keep this flow, re-evaluate the verbiage.
I like the design and layout of the site though! maybe add a few more tool tips about what each column means. i know a little PPC terminology but not enough apparently..
