BOOSTER SEO & IMAGE OPTIMIZER

Unfortunately this app did not work at all for me. After two days still no image Alt text had been changed. So I triggered it again, still not working after a Week no Image alt text changed. I would understand that it takes a bit and slowly get this images done one by one but not non in an entire week seems useless. Also no feedback from support chat. I contacted them 3 times over 4 days. I was looking forward to use this App as it looks good and promised a lot, but then I got extremely disappointed.
