The speed you pages load can be crucial for retaining users. This has always been important and is all the more so on mobile devices. A delay of even a second can lose a user.
Google have a tool, "PageSpeed Insights" that lets you see what elements of a page are slowing it down and makes suggestions for speeding it up. It gives the pages scores out of 100 for desktop and mobile devices. It rates issues in three categories.
Red warnings - where fixing the issues will make a significant effect.
Yellow warnings - where issues should be fixed if possible.
Green check marks - where no issues have been found.
It also has links to Googles optimisation tools which can help solves some of the problems highlighted.
Well worth trying to solve current problems and get you into good habits for the future!
