Web 2.0 that ranks good in google today ?

I am looking for sites that ranks good in google for longtail keywords to place my link to money site, i know youtube is good but have to much keywords to make video for every one keyword, i tried twitter, but statuses doesn't rank in google, tried yahoo answers but they banned me fast, can you recommend my any good web 2.0 ?

weebly and webs

Yeah weebly and webs are the two I was going to recommend especially since they tend to let you post about any kind of content. To find more look up the root domain for the web2 you are considering in SEMRush and see what they rank for.

plenty threads with the list of them

Yola ranks well for me with custom domain.

ya, now a days i mostly see web 2 blogs ranking in good position

weebly, tumblr, webs, wordpress and blogspot are ranking well in google.

Subdomains of any WEB2.0's can rank well if they are decent.
If Google has given a site you can put your content on a PR of 2 or higher - it thinks it's pretty decent.

Some require a little more work to push your own URL';s or subdomains - some don't.

If some didn't rank for any keywords at all in the top 20...they wouldn't exist unless they were brand new or in the process of being removed

The thing about the profiles you create on 3rd party site is..80% of their ranking potential IS DOWN TO YOU not the host domain.
Don't get hung up on the 20% authority transfer from the root - think more about the 80% that YOU can provide - and by doing so widen the number of unique URL's unique platforms and IP's that your first tier links come from.

You can make as many Weebly subdomains as you like - Weebly runs on about 5 servers (and you don't get to pick which one your SD is created on) so the IP spread and domain spread of inbound links is almost zero. Once one of your URL's has a couple of links from one 3rd party site - creating more from the same domain won't help at all - and might even cause Mr Penguin to "come a knocking"

What's the first rule about SEO in 2013.. We all talk about VARIATION

... Can you guess what's next?

VARIATION

In the placement, platform, authority, Rel, IP and anchor text of links.

does any1 know the best pkg here to rank webs good?

Depends on your site
There is no "one solution fits all" in SEO
Some great packages here but their effectiveness depends on the type of site you have, your content, your existing links and your competition among other things.

As it is asked no-one can give a proper answer to your question
(Though I'm sure some SEO noobs might try)
