If you are wondering if Facebook advertisements work the answer is that they do work. It is true that the ads do not get as many clicks as those on Google but that does not mean they do not work.
Google ads get more clicks probably because people on the site are in a search mode and the advertisements coincide with the search. They are already in more of a mood to buy. Facebook is not the same kind of site. It is a social networking site.
So, can you say that Facebook advertisements do not work? No, you can not say that. It only means that it will take more people to see the advertisement to get the same number of clicks as Google. But deciding if something works should be based on profit and not the number of clicks.
There are many people who call themselves marketers who would say that Facebook is not effective. They usually are basing their review of an advertising campaign on the number of clicks. That does not matter if you are being charge per click. It is the revenue that matters the most.
A seller of products knows if an advertisement campaign is working in one simple test. They look to the profit that is being made. A review of sales data will make this obvious.
For example if you make $ 200 in profit for an advertising investment of $ 100, it is clear that the campaign was worth it. This is how you must analyze the effectiveness of the time and cost of producing the advertising.
Sellers are always trying to improve the effectiveness of their advertising. Analyzing the results of your Facebook advertisements will help. Look at results side by side of more than one ad that you are running and decide which had the best profit margin per click.
You need a good number of advertisements running at the same time to get this proper analysis.
