I used all preferable by SEO methods and techniques:
1) Good and clear content with keywords included. I often update some parts of the content.
2) I have filled all meta sections, included keywords and title
3) I used keywords in heading H1 and H2
4) Vast majority of pictures (those I was able to do that) have alt attributes filled

I have never used any illegal methods for SEO purpose like black hat techniques. Maybe they are good for short time but not for long perspective of your website and I don't recommend to practise them at all.

I could make my website better but it was created on weebly so I could not avoid using tables for layout of pages because they were part of weebly tools I used.
That's why I am going to build an alternative website in the future and then I will have much more control over  html and css code keeping them clear and optimized for SEO purpose.

We are very pleased to hear that our page rank PR has risen from 0 to 1 today. It is good news for us because we started to run our website just a couples of months ago and achievement of 1 point in scale 0-9 in such a short time  is really very successful.
