i have a website ranked w/ alexa 748,234 but not ranked with google why.
www softwareforpc.net

It probably means you have the Alexa toolbar installed and visit your own pages a lot!

I'd suggest you to make the URLs on your website SEO friends... and user friendly as well. When anyone loads your domains name it redirects to softwareforpc.net/cart/page.html?chapter=0&id=9

This is not a good practice!

Well... as the previous poster said, your URLs are horendous... Not SEO friendly, and not user friendly. Your on-page/on-site optimization is not good. With a domain name like SoftwareForPC.net, I would assume you would be going after keyword phrases like "Software for PC" and "PC Software"... Yet your home page has the following <title> element value:

Home :: SoftwareForPC.Net - Superb Products

That is a terrible <title> element value. Including "HOME" in your title? WTH? Trying to rank for home? Including your domain name in the title? Again BAD idea? Trying to rank for "Superb Products"? No one on earth searches Google for "superb products".

My suggestion to you is reevaluate the platform you built your site on. Find out how to make the URLs search engine and user friendly. And go back to the drawing board for your on-page/on-site SEO.

Once you have a good information architecture, have optimized your pages and site, THEN start working on link building to your home and inner pages using those pages targeted keyword phrase(s) (from the title each page) as the link text for their inbound links.

SEO is your friend mate. Forget Alexa for a moment and get some good resource for SEO. That's the only way your site is going to rank in the search engines.

you did not add keywords in you website, alts, HI Tags is not there, how can google catch your website ??
