It’s good for searchers –
Research indicates that searchers click on paid search ads more often than any other form of digital advertising. This means that people really don’t mind being advertised to, provided that the products and services advertised actually fit the searcher’s needs. And because we use search engines when we’re looking for products and services, the results, including the ads, are generally highly relevant to what we’re looking for. Plus, Google has developed an excellent formula for ensuring that PPC ads meet the user’s needs.
It’s good for advertisers -
Advertisers are offered a unique means of putting their message in front of an audience who is actively and specifically seeking out their product. Because searchers reveal their intent through their search query, advertisers are able to measure the quality of traffic that results from search engine clicks.
It’s good for search engines –
PPC enables search engines to cater to searchers and advertisers simultaneously. The searchers comprise their user-base, while the advertisers provide them with their revenue stream. The engines want to provide relevant results, first and foremost, while offering a highly targeted, revenue-driving advertising channel.
