Thank you Rich I understand all that how Google search works, but I'm not sure if my articles show up in quoted result and not shows in not quoted result are good or bad thing.

You want them to show up, ie. "rank" without the quote marks as that's the way the majority of people search. However, it's worth remembering that search engines are businesses, not public services. They want to give their customers, ie. "searchers" the best experience possible, so they're not going to offer up a site in their listings until it will give their customers value if they click on the link. Rich.

I see so what you mean is that if I keep creating good content sooner or later I'm will have the ranking I'm looking for. I decide for myself that will devote at least a year in this so there is plenty of time to reach all the ranking I want.

Thanks again, Rich

Yup! You add a different but relevant keyword in the title and first para of each page or post. If you add a new post to your site twice a week for keywords with c. 100 monthly traffic that'll be 10,000 potential visitors per month to your site within a year. :) Your site becomes an "authority" as it ranks on the aggregate. However it's worth remembering that search engines don't buy anything, people do, so always aim for the best possible visitor experience, regardless of any SEO considerations. :) Rich.
