Home service marketing methods have changed over the years. For big companies, there were TV ads, radio ads and magazine ads. For smaller companies, there were the Yellow Pages, newspaper ads and billboards. These methods all still exist and may still be appropriate and useful for some companies. I would call these traditional marketing methods. But the Internet changed everything.
The first thing the Internet did was increase the capacity for volume of advertising slots available. In TV, there are only so many slots for a commercial. Same with radio. Magazines and newspapers could print more pages but to a point. There are only so many billboards. But, the Internet added an almost unlimited number of placement opportunities.
The second thing the Interned did was change the target that was possible with marketing. In traditional marketing, you could sort of target potential customers based on the medium that were on like a sports magazine or a sports TV channel but it was still broadcast messaging. The Internet changed this with the volume of context types and the narrow topics that were possible. You could have a website with a very specific sport type and feel that your specific audience was viewing those web pages.
The third thing the Internet did was allow direct targeting. The best example is ads on search engine results. People were searching for some specific and you could bid to have your ad show on specific keywords.
Finally, the Internet allowed that ads and ad budget could be changed immediately. There was no waiting for the TV show to air or the magazine to be printed.
Home service marketing methods have changed greatly over the years with the Internet. There is more volume, more targets and the ability to make changes quickly.
