Look up ad-blocking browsers for your phone. I use Apollo when browsing sites that have ads on them. I don't know if you have to pay for Apollo though. I've used it for so long that I have forgotten. XD I use Apollo on both my iPhone and my iPad, and it's just as effective as Ad-block is on Firefox and Chrome.
Edit: I googled Apollo Browser on my laptop, and it looks like it is free. I'd consider giving it a try if you want to get rid of all the ads. I'm not sure about android or anything though. I only have iOS right now, so I can't speak for the others. :/ I'm pretty sure it has zooming capabilities, but that might depend on the site itself. I've never used Apollo on my phone before and only my iPad. Since my iPad is bigger than my phone, I don't really need to zoom in to a website or anything.
