How am I doing so far? and some questions

Hello Warriors,

I started to read Warrior Forum 2 months ago and made my first website which I promote Amazon products about 35 days ago.

When I registered my domain which is an exact match domain I was thinking that it was a micro niche keyword pattern but after I see it was a very competitive niche and it is not a micro one too.
It is like "x for y" where "x" can be thousands of products from $1 to $1000s and "y" is a certain group of people.

I am building my website slowly and trying to get as much as backlinks, all done by me.

As I said it's been 35 days from the launch, I want to show important steps/days so that I hope you can give me some advice, or tell me how am I doing so far?

1- First 5 days I customized/learnt WordPress, tried some plugins, themes,
made a logo, buttons etc and I created some basic content.

2- After first 5 days, I started to post content (product pages, articles), and some made some backlinks (social bookmarking, commenting, etc...).
My site climbed to 1st page of google for my main keyword .

3- About day #20 google sent me to page 8 and started make more backlinks and content.

4- On the 25th day I sold an Item which I got $1 and started make much more backlinks with a smile. I climbed to page 2 again and it seems I am stable there.

5-For last 10 days I am seeing improvements: I am getting 50 visitors 30-40 from search engines daily. I sold 3 more items last 10 days which make me another $10.

So, here are my questions:

1-Am I going too slow? (about 50 visitors a day).
2-Is it OK to not post new page/post but only improve the content of existing ones (ie. making them more content rich, add more photos)?
3-Was it the google dance which put me 1st page then 8th page? (now I am page #2)

Any suggestions are welcome.

Thanks in advance.
