I was wondering that which niche can earn the most money from displaying google adsense's ads. I know that technology is one niche but how about the others?

How do guys cope with an attack of web 2.0 sites? I am not saying about a couple of sites but hundreds of them. And they keep coming from different sites of wordpress, blogspot etc.

Many sites is getting manual action penalties from Google recently. Are you guys seeing this too?

I am not sure what is exactly causing it? Because inbound links are good I checked them and there are no pattern among the sites as well.

Which ad agencies provide Twitter offers? Like the sponsored tweets and all but for CPL or CPA offers.

Here are two types:

1. One product email (which is solely for product promotion) per email campaign. Which will contain atleast 10 emails that will include free stuff.

2. Every email should have a slow pitch for the concerned product after throwing them free stuff and weekly newsletters.

Which one is more preferable?

Apart from the bidding and running the campaigns. Many ad agencies require a small set up money. As I know here are many marketers, so my question to you guys is how much do you guys charge to set up an ad PPC campaign?

Okay I have two version of my site which I can apply in order to make the site responsive. One is made of javascript and the other one is part of many languages along with HTML. The later on is very easy to manage though because many developers and involved so management and customiztions are pretty easy for users. Which one should I choose?

How do you guys do it? Many hires help!!! So, if you do hire someone then do you guys provide the resources too.

If you are getting some good tier 1 links from PBN's which are built on expired or aged domains. Then what will be your strategy here. Where you will point those links to? (homepage or internal pages)

We published few articles last week. They suddenly appeared in the first page of Google without much effort. But then after a day or two they fell into the second page. And in that position they are fixed now.

Why this happened? Is there any thing I can o to get the previous rankings back?
