Lots of business use paid search such as Google AdWords in order to maximise their search engine results when customers search for their products. This is not necessarily the best way to spend your marketing budget however!
The problems with paid search is that you end up spending quite a lot on getting very small results. Without the correct setup, many PPC campaigns are simply not as effective as they should be, wasting money and time for all involved.
If you are certain that paid search is the right one for you, it is always worth seeking the advice of a digital marketing expert, preferably one who is Google AdWords certified. This way, they will be able to maximise your campaign and get the best results for you in the short and long term.
