I've heard alot about content updating, how important it is for better SERP positioning.
Of course, this is just only one of the important things to do, but I want to know are there any criteria of how often and how big should be update to be considered by Google as good enough to raise the SERP position.
For example, my site is dedicated to supreme clothing and the brand name coupon codes. I have a lot of subpages that I update almost on a daily basis. But my home page is very general, and I usually update the content slightly. (Mostly promo expiration dates and some major sales). But this is the main page which reflects my
PR and my SERP.
Do I have to update my home page more often? I also wondering, what percentage of the page should be updated to be considered as good enough.
Any help is very appreciated.
Have a great day,
