GooglePage Rank & SEO

Google page rank - "is a link analysis algorithm which assigns a numerical weighting to each element of a hyperlinked set of documents, such as the World Wide Web, with the purpose of "measuring" its relative importance within the set. The algorithm may be applied to any collection of entities with reciprocal quotations and references"

Wikipedia

Search Engine Optimization - "as a subset of search engine marketing seeks to improve the number and quality of visitors to a web site from "natural" ("organic" or "algorithmic") search results. The quality of visitor traffic can be measured by how often a visitor using a specific keyword leads to a desired conversion action, such as making a purchase or requesting further information. In effect, SEO is marketing by appealing first to machine algorithms to increase search engine relevance and secondly to human visitors"

Today i have found that corp site of my company (OBS Group) has google page rank "1". I think that it's a progress for it and for me, because it was my first SEO experience. Now, I am going to continue training on it. I am sure that expert knowledges in SEO area are very important for everyone success start-up.

How To Start

At first, I have to decide what business I'd like to start at first. I have one - "OBS Group" and now i am going to start an other one. I am sure that the most perspective business is e-Commerce and Web 2.0 Application designed for the end-user. What are the difference between investments to them:
- e-Commerce requires for much investments at the start of business.
- Web Application requires much fewer investments at the start, but then it will require much and much more.

Also i decided that i must select the idea not by first time investments, but by the ROI
(ROI - return of investments, some venture capitalists have ROI more then 1000%), That's i the most important criteria. At first, Entrepreneur have to think about the win and the feedback not about the possible losses.

As known, in 10 start ups:
2-3 - return money and generate some positive cash flow
3-4 - only return money
3-4 - loss money of investor.

No one shouldn't forget about that, every one must think about possibility of the win.
