Hi I am thinking about changing the size and type of font on all of my webpages and am very worried for some reason that my website might get penalized.Will Google penalize me If I do this?The content would remain 100% the same with no additions or removals but just changes to size & type ( all the same ). Thanks
I have that and never heard of any penalty when changing font size - consider pt vs px font size to have a solid stable size on all displays across the industry!
The important factor about font size is if you change a portion of the text to smaller or bigger, Google may consider the keywords as less or more important. Any normal text size should do the job. Ranking in SE is about how relevant is your text and not how it looks.
