We have a website that has around 15 content pages which is same for every page. It cannot be changed because it's about product information and services information etc. So, those pages' content we cannot change.
What should I do to get my site constantly updated? Should I start a blog for my website that will be within my own website and I start posting content related to my business? Will that do?
In short I am confused about if a website is product based, how to get it ranked higher in Google?
