As time is passing Google is pushing adwords investments more and more. Should we be considering to increase our ad budgets?

I am very much confused about. Can anyone point me to the right direction here.

Seeing some pretty hard changes in the SERP's today. Not to mention traffic from other search engines are going nuts.

Are there any good free keyword generator?

Putting a Clickbank product in my site's homepage does it mean that I have to get a sales like Amazon?

Seeing a lot of drag after installing Mobile optimized theme. Any suggestions?

There are two types of situation here.

1. The kw will be "Top Perfume", where all the sub-niches such as cars, home, offices will be targeted from a single page or article.
2. The kw will be "Top Perfume for car/offices/homes", where all the kw's will be targeted through separate pages.

From SEO point of view which will be more beneficial.

I just bought a very old domain in our niche. Its almost 20 years old. And it has got some good links too. But don't know how to proceed now. Any advices??!!

Suppose there are two pages on one site which are similar and audiences often overlap with each other. Now both of them may exist but only one of them should rank in the rankings.

The things here is like "iPhone 7" and "iPhone 6". Both of them should have their own pages but the page having the latest version of iPhone will rank. In this type of situations what should I do to get my desired page ranked better?
