Loads of clicks and any lead, quality issue?

I work with different affiliate networks, and i always have the same problem, 300-400 clicks and any lead. No matter which offer I'm testing.

And the worst of all is that in the beginning the offers were working me very well.

I was testing an offer, and in the first day i had a good conversion rate, but at the second 0. then I put in the top of the landing another that had for example 3 clcicks and a conversions the day before, but suddently the conversions went to 0.

At the end, all the campaigns of the network(s) were generating me 0.
Once I could run a campaign for a month, just after begining to work with a new affiliate network, but the advertisers were paused.


I tend to use very focused traffic.

I have been using many traffic sources: Adwords, Facebook, PoF, Bidvertiser, Adon network, Microsoft Adcenter...

The result is the same, Clicks but no leads.

I tried to change a lot of things: look for viruses, change my websites of country, change creatives (The favourite explanation of some AM's), obviously test new offers, split test my landing...

When I say that i have 400 clicks and 0 leads, i mean that I have something like 1000 visits to my landing and 400 click to the offer.

The load time of my website seems fine (I changed my website of contry to make it faster but any result )

I contacted many times with many IM's in different networks, and the only reason it could happen, seems to be a filter advertisers use to automatically scrub leads that do not convert them.

Then I began to google thinks like: "Affiliates send me Junk traffic"... And it seems that they do that If somebody is sending them like 300000 clicks from an autosurfer or a virus, but i do not do that, after 700 clicks with no leads, i quit promoting a campaign. I think that i do not have more than 100 leads in the last six months in total.

Last year I Was working campaigns in Spain That weren't doing that (I think that telling the reason I scrubbed spanish networks will be against forum's rules), But i decided to work with (some) US Networks , and US campaigns with US traffic. The campaign I've been running for a month was for spanish traffic.

I do not know if the last does matter, but anyway, some AM's tell me that what is happening me is very strange. I'm in a blacklist or something like so?
