It looks like that Google will replace its search results pagination with a “Show more results” button. This JavaScript button loads one page at a time without refreshing the page while scrolling down to the page number. This could be a reminder that Search Engine Optimization is extremely necessary for all businesses because it would take awhile to get to other pages. Check out the screenshots below:
