Analyze regularly and collect enough data
There are two extremes: monitoring the results every minute and making hasty decisions, for example, that the ad did not bring a single client in a day and it needs to be turned off. The second extreme: set a budget for a week and check the campaign only after seven days. Keep your finger on the pulse. In order to properly evaluate advertising, it is important to wait until there is enough data. It is also important to understand that user activity can depend on other factors - seasonality, competitors' behavior, the release of new products. Therefore, even if the ad worked well the first time, it does not mean that you can launch it in a couple of months and not monitor the results.
Study the dynamics
There is no ideal number to aim for — perhaps 100% conversion, but uses of twitter we live in the real world. Even within a single niche, the metrics vary, so focus on your campaign metrics for different periods and offers. For example, you see that the cost of attracting one client is gradually decreasing — and this means that your ads are working.
Test and validate hypotheses
When working with advertising, you need to be flexible and adapt to constant changes - both in the market and the audience. It is very rare that you can just take and create a campaign that will bring stable traffic for months. Advertising systems change and develop, new tools appear. Use them, create hypotheses and test to get the desired result and scale successful advertising.
