Marketing on Internet Road 

Employing Internet Marketing strategies does not necessarily mean a new way of doing business. It is true that the internet and online marketing opened up a window for new and advance way of doing business, but it is also an online reflection of the way you do business offline.

Ask yourself the following question: “How do I get business today?” This answer should lead you in to the best main strategy you need to be using in your Internet Marketing portfolio.
If you are doing business by more than only one method, use more than one method online. Furthermore, extend your online marketing efforts to be using more than one main strategy. This way you can significantly increase your business while still being very efficient, be able to make constant changes and keep the costs low (surely when compared to your traditional marketing tactics).

Word of Mouth and/or Networking

With Word of Mouth the most important factor is referrals and positive reviews on your products and services. The best fit is with Social Media Marketing.
Depending on your exact type of business, choose your Social Networks: LinkedIn (mainly if you are in B2B), Twitter, Facebook and so on. Social Media is all about connections, referrals and experiences people on those networks experienced. This is literally the new way of Word of Mouth.
The complimentary Internet Marketing strategy to use is permission based Email Marketing: use your website and other online touch-points (like you page on Facebook) to encourage customers and prospects to subscribe to your mailing list. Then, send them timely newsletters to keep them engaged and further encourage them to forward your messages to others.

Cold Calling

If your business depends on Cold Calls or incoming phone calls, your strategies should combine Search Engine Marketing together with bought-list-based Email Marketing.
The Search Engine Marketing strategies of Search Engine Optimization and Pay-per-Click will ensure your phone is ringing. They are designed to get you found by your target market and potential customers exactly when they are looking for what you have to offer, where they are searching for it and in the way they are searching for it.
If you can purchase bought lists of your potential customers (watch out for legal aspects depending on your location and the vendor), this is a very close match to your cold calling tactics, only via the internet – much cheaper, more flexible and more effective.

Advertising

If you focusing offline on advertising, online you should put your focus on
-   SEO
-   PPC
-   Display advertising

As mentioned above, Search Engine Marketing tactics are the best ways in the online realm to reach your target audience. Done correctly, it should be much cheaper and much more effective than your offline advertising efforts. Consider allocating part of the traditional advertising budget to the online realm.
If your advertising budget is more substantial, explore the possibility of using Display Advertising: literally advertise your business (that is – your web pages) on websites that your potential customers visit. Display Advertising constantly improves and allows more capabilities of socio-demographic targeting to make your campaign more accurate and more successful.  

Face to Face

If your business depends on Face-to-Face meetings, make sure your “face” is visible online.
As this type of prospecting suggests you are in the B2B market, invest in your LinkedIn profile along with a professional profile on a Facebook page.
Furthermore, use YouTube to host videos on your business, your offerings and your sales representatives. Similarly, upload photos to Flickr and presentations to Slideshare.
Make sure to have a professional profile on each of those networks as this is one of the first things people will look at and will help them have a positive perception of your business.
