I'd need to know the content of your business before I would make a recommendation. But here are three media I often use for my clients:

LinkedIn: Networking and ads.

Service reviews: find a blogger who needs your service, provide your service for free, get him to write a blog on it, leveraging his readership.

Business critiques: Write a critique of a business that needs your service (~2,000 words), post it on your blog, spread the blog post to that business via social media (best), email (still good), and phone (as a follow-up to email). This has been the main way I get clients for my business HedgeSys

Here's an example of that latter strategy: Audit: Man Group | Damon Verial's HedgeSys

I suggest you some ways which help you to increase your website.

Social Media sites like G+, Twitter, Facebook, Tumbler, Linked In and so on. You can use those social media sites in order to get more traffics.

1. Make sure your websit is well optimized
2. Provide the high quality content
3. Newsletters :get the consumer's email
4. PPC ad campaigns on Google & Facebook to your blog
5. Email marketing the fastest way to generate leads

This is a good example of a useless question. B2B narrows it down very little, and it's almost impossible to say anything at all without more information. I guess the frowny face should be taken as something along the lines of "I'm not seeing the results I'd like".

There's some generic advice in this thread, but Google would find you lots more.

1. Provide the high quality content
2. Newsletters :get the consumer's email
3. PPC ad campaigns on Google & Facebook to your blog
4. Email marketing the fastest way to generate leads

1. Start with Press release, you get the word out, get lot of visitors to your site, and gain trust and authority in the eyes of google. There are many such services use a good one.
2. Use social media - twitter, facebook, youtube, google+ : not only you get visitors from social media sites, but new Google algos, give good weight age to social signals.
3. Try to link with other authority sites in your niche. Getting recommendation and links from authority sites in your niche - gains high authority points from Google, and also get good no of visitors too.
For this you have to contact multiple sites with some bait, praising their sites etc, thereon its a numbers game
4. Try to provide good content, and setup your site as a brand, with good content, you will have good visitor engagement metrics - that is high time on site, low bounce rate etc - which is another factor in updated Google algos
5. Lastly get good backlinks which is like 70% of SEO, but try to get them from authority sites in your niche, and mix up with sites in other niche, There is no 1 way to do it, you can outsource it, or have other sites to exchange or build up your own network.
