Banners exist in many different manifestations. The net and the frontlit are well known and seem to be the most commonly chosen. You can choose the right one according to your particular situation - what exactly you will present or advertise and what you want to achieve.
The mesh structure is particularly popular. This structure makes the banner look great, but at a short distance, so it is less appropriate in terms of visualization.
The banner foundation is really important, but perhaps even more important is its content. The picture and text should be so well matched and matched that they instantly catch the attention of anyone who sees them. If the combination is done correctly, then the likelihood that the potential customer will follow the link and turn into a real one is really very high. This would mean that the goal is fulfilled and the advertising is successful.
For your banner ad to be as successful as possible, leave the banner creation to the professionals. Just present your goals and ideas to them, and they will find the best way to realize them.
