Creating GIFs designed for the Google AdWords platform can be tricky, given the file-size constraint of 150Kb.
I looked for examples online and found this page: http://bannerspiration.com/gif
Not all of these meet the second constraint for AdWords (fps should be lower than 5), but the file size is good for all of them.
My outputs are full of artefacts and I have no idea what to do to increase the overall quality of the picture without using a higher file size.
Any tutorial, advice, suggestion, would be highly appreciated.
Below you can see one of my examples that worked well and one that has compression artifacts.
