Asking if it is best to spend more on Pay Per Click (PPC) or Search Engine Optimisation (SEO) is a little like asking if you would like cake or ice cream, it normally depends on the circumstances at the time.

Pay Per Click is a great way of getting an instant boost for your company, getting the traffic in through the doors when the site is new so that you can test to see how popular the products or services you are selling are going to be, using relatively mall amounts of just a few hundred pounds you will be able to gage if people are interested in what you are promoting.

Once you know they are interested you can begin your marketing in full force, increasing your Pay Per Click budget and bringing in SEO for the site, Search Engine Optimisation is a longer term strategy than the PPC, but it does have the advantage of continuing to run even when you have stopped paying for it, although if it is stopped prematurely in a competitive market you can see the good positions drop quickly.

You are a little limited with the terms you can promote for with PPC as budget is always a concern, but with SEO you can promote for as many phrases as you like and you will find you are being found for phrases you did not even know were of interest to your visitors.

Rather than using PPC or SEO you should be using a combination of the two so that they complement each other as you move your marketing efforts forward, testing new markets with the PPC and promoting your site into the profitable niches using SEO.
