Effect:

First of all, see if the website can achieve the function you want. If the function is not satisfactory, it must continue to be improved. This is the premise. Then look at the UI of the website, that is, whether the layout and color matching are satisfactory or not, and improve it if you are not satisfied until you are satisfied.

Efficiency:

This includes development efficiency and website response speed.

There must be a plan before development. Whether you are developing yourself or looking for someone to develop, you need to plan. We must develop according to the plan. This is development efficiency. The second is the response speed. Now the bandwidth is very large, and your website must be opened quickly. Think about it, if a page takes 2 seconds or more to open, who will want to visit it? If there is a problem in this area, we must optimize it. The front end will see if there are any pictures loaded asynchronously, whether the pictures are too large, and so on. The back end mainly does database optimization.
