Bidvertiser is Legit ??

ive used it, only for the free credit , CTR is low. i cant verify the traffic but cant complain for free.

From what I remember a few years back, if it still even holds true today -

As a publisher: High EPC, pays more per click than adsense but lower ctr
As an advertiser: Never used them but I guess it's okay if they're still in business since I really preferred adsense over them as a publisher.

I haven't checked up on them in the past 2-3 years however so things might be different now.

i used it now they only low
because they give every new advertiser 20 dollar for free
and will not count that clicks
