Adwords Campaigns are now failing

[marketingS]

Previous our adwords campaigns were very successful but now they failing. The conversion rates are falling every single day. I have no idea what went wrong.

What you are providing is very little information. We can't suggest anything based on it.

One of our landing page for signup was working pretty good. But since last week the conversions are falling. We are running the same PPC campaign through Adwords with the same landing page.

Have you changed any parameters of your ad campaign?

We haven't changed anything.
