Big font in google in safari?

when I search something on google in the safari the first two results have fonts that are way bigger than what my iphone is set to and then the rest of the results have the normal font size. I double checked in my settings and the font is set to be smaller and there the zoom is off. I only have this problem when I use safari, every other app has the normal font size that my settings is set to. Why does this happen and how can I stop it?
