If I get a link from a very popular site then will it help in rankings?

Mobile pages are not getting indexed in Google at all. They are not even getting crawled properly. Why is this happening?

Get people emotional it can get you sales. Rational people takes lot of time to take the leap of faith which is called sales. Every marketer here I am sure believe in this theory but everyone work on it everytime??

Here is the two scenarios. Which can work better for a eCommerce site?

Target audience by general PPC or target via highest bidder. I am not talking about lead generation here. I am talking about good exposure that can lead to sales in return in the near future.

In a very closed community of marketers. They discuss about products and have recommended me some of them. It may sound odd but in our niche it occurs. Now here is the dilemma. I think the products are good but I don't know what will occur in the long run.

So, I am having second thoughts about it before investing big bucks in it.

How to market a product which sales at an extremely low price?? Say about $2 or $2.50.

Every scenario that I can imagine in order to run a campaign for it, needs atleast $15 - $20 in adwords or fb ads.

What should be the correct business strategy for this?

Bounce rate is getting bad and worse day by day. Our search traffic, I mean the organic traffic used to have below 20% bounce rate.

And now after the June updates and other indexing issues by Google it has gone upto 40% and now its increasing day by day.

This is the overall bounce rate of our site. Any suggestion?? that would help me.

Creating a bunch of sites and then linking back!! Only by doing this my main site is going to rank?

Which is the best ESP with the best customer support. Recently, I had a very bad experience with some and I am not going to mention them though. But still I will say that even though when you pay good money it's not sure that you will get a good service.

If same article is published in two pages of one site then will it create any issue of duplicate content? If yes, then how can it be resolved?
