I have two SEO optimised pages in my website targeting different keywords

www.example.com                 <-- main selling page (Pocket Guitar | Guitar Instruments)
www.example.com/index/       <-- 2nd selling page (Guitar Australia | Guitar Perth)

Q: At first my website "www.example.com" is ranking on google first page. Suddenly it disappears and the link "www.example.com/index/" appears instead.

No matter what i search, "Pocket Guitar | Guitar Instruments | Guitar Australia | Guitar Perth", the link www.example.com/index/ appears on the front page instead of www.example.com.

What is happening to my main domain? Should i be worried?

From the above example u can see that "Guitar Strings USA" appears in H1 and H2, is it okay? or should i remove it?

I remember finding a tutorial on MOZ about how to remove low quality links. But i cant find it now. can someone help?

Hi guys, my H1 code is like but Yoast SEO and Google Page Speed keeps saying that i do not have a H1 tag in my website, Is my code wrong?

Keyword | Keyword2

Under "http://moz.com/blog/everybody-needs-local-seo"

Q) There is a paragraph saying "If your business has multiple locations, you should have a unique location landing page for each Google Plus Local listing."

Does it mean that for each of my shop (location), i have to create an brand new google plus page for it?

Q) There is a paragraph saying "you're dealing with a single location, then we're talking about your home page - but these elements should also be locally optimized on product and services pages. City and state in the title tag. City and state in H1 heading"

For example, if my country is australia, i have to create a page within my website and the it is optimised to the keywords "Gold Coast | Australia" in my 'product and services page'?

Is there a tool in MOZpro where i can check my sitewide links?

Is there any helpful articles regarding sitewide links? Im confuse about (1) how to detect sitewide links (2) are they harmful or not (3) how to remove them.

Sample Scenario
I have 5 websites (www.sample.com) targeting 5 different counties
www.samplecn.com (china)
www.sampleny.com (new york)
www.samplekr.com (korea)
www.samplejp.com (japan)
www.samplesg.com (singapore)

On each website i have a flag logo on every single page/ header allowing users to select the other websites. After 4 months, i end up with 200,000 backlinks from all the other 4 websites

Why am i worried: I find myself ranking #1 for a lot of the keywords for the 4th months straight now without doing much SEO optimization. And there are alot of websites below me which have better and more informative site than me. Should i be worried? am i doing something called "sitewide links"?
