The marketing strategies:-
1. SEO work and submitting them to all major search engines with target specific keywords.
2. Submitting to social bookmarking sites.
3. twitter.
4. forum posting with signature and blog comment(no spamming)
5. article submission
6. press realease submission.
7. submitting sites to all directories..

Articles and forum postings are the best way to promote resources for getting good traffic and visibility in search engine result pages. These resources are beneficial because they cached/indexed frequently by search engine and increase the backlinks for the website.

Best marketing techniques are...forum posting, social bookmarking, Directory submission, PPC(It's paid service) banner advertising...Press release submission...

Well it depends on the industry you are talking about. My best experience has been getting organic traffic from the search engines. Also it is wise to use AdWords just so Google becomes even more familiar with your site.

In regards to best, think of the strategy that will get you the most targeted visitors, this will be your best strategy.

Of course I am tempted to say that our model is the best ( because it's purely performance based) , but then it wouldn't be modest :-)

Well, there is no cookie cutter to answer to the question and give the best, of course. "The best" for a company with $10 budget significantly differs from "the best" for a company with $100K marketing budget. "The best" for content site is not "the best" for product site.

The mantra is always engagement and reward for spreading the ward... either emotional or material. Give your user a cookie (but not any, one he wants) and he will sell for you better then your own sales team or investors whose dollar is in the game.

Some of the best marketing practices include

Social bookmarking
Articles submission
Forum posting
Blog commenting
Classified ads
Social profiles

If you can get a link of your site on an authority site (a site that Google ranks as holding more weight than most sites), it will promote your site extraordinarily well. In some cases, the ROI is well worth a significant investment on a link.

nice one i agreed it.

It really all depends on what you're trying to accomplish. What kind of individuals do you want accessing your website? There are many different routes to go. I'll offer you this:

Let's say that you're trying to attract big players within your specific industry to go to your website. You want these individuals to see your site as well as use it's features and functions. Most likely, big players already have a whole bunch of sites they like to frequent. In order to attract these guys, you would have to go to trade shows/conferences/seminars/networking events. This way, there's a face to your website. The better you present yourself and acclamate yourself with these individuals in person, they're more inclined to visit your website. Hopefully, your website is really good and they recommend it to their friends. Before you know it, other big players will be tweeting about it and such and then the traffic will follow. You really want to stir a buzz to generate traffic.

If your site is dull/boring, doesn't really offer anything, then there are obviously other avenues to go through. I would certainly hope you're not building a content farm/junk site and actually adding value to your visitors. Remember that added value brings about retention which is key when operating a website.

With that said, as long as your meeting big players face to face and have a solid website, then that's the best way to generate traffic. Social media is the most powerful traffic building option out there. It really just takes one tweet to draw a lot of attention to your site. Go get em'!
