facebook ads don't work

 Ad Relevance To Audience
As we mentioned in the last section, part of the “total value” is the relevance of your ad, which is based off of the direct feedback that your ad gets from your audience. If they interact with it in a positive manner – likes, comments, shares, clicks – then your relevancy score goes up. If they interact with it negatively – reporting it as spam, hiding it from their timeline – the score goes down. You can view your relevance score in Facebook ads manager, and you should pay attention to it because it matters for how much your ad is shown to people as well as how much it costs.
We also mentioned earlier about creating a profile for your target audience. Well you can use that profile to create ads that are relevant to them, thus they will perform better. If you know your target audience, generic ads aren’t what will make them interact with your ad.
To fix this issue, you should always design your ads so that they are specific to the audience you are targeting. This, again, requires an accurate profile of the consumer. You can also fix your relevancy score by creating ads that are more relevant to your audience. You need them to interact positively with your ads.
