- 1. Why is the cache plugin important?
If you don't feel like your site is loading fast enough, using a caching plugin is the quickest and most effective solution.
Just like the old computer has poor performance, slow speed, and can't replace the core hardware such as the CPU or graphics card, but as long as you replace a memory module, the performance of the old computer will have a qualitative leap.
Websites that install caching plugins reduce the pressure on the host server, load significantly faster, and improve website performance.
Such a good user experience can naturally retain more visitors, indirectly improve SEO rankings, and get more Google traffic.
- 2. Cache plug-in recommendation
I have used 6 mainstream caching plugins before and after, and based on my subjective experience, I make the following recommendations:
①、优先推荐WP Rocket
WP Rocket is the cleanest and easiest caching plugin I've ever used, and of course, the caching effect is pretty good!
With the GTmetrix score, it has always been the highest score, and few people can beat it.
The only downside is that there is no free version, and you will be charged when it comes up, which is $59/year.
It doesn't seem to be its drawback, though, it's mine...
(2)、备选Speed Optimizer和LiteSpeed Cache
Both of these are cache plugins that come with the host, which are not only completely free, but also highly compatible with the server.
Overall, the TTFB value is quite satisfactory.
After optimization, several important Google Web Vitals were able to achieve high scores.
(3) WP Super Cache, W3 Total Cache, WP Fastest Cache are not recommended
All three caching plugins are also free, but I don't recommend them because it's a hassle to set up.
Take WP Super Cache as an example, I once spent a week not setting it up, and there were all kinds of bugs all the time, and I used to think that setting up the cache with it was "metaphysical"! The official caching plugin is too bad, right?
W3 Total Cache and WP Fastest Cache are not much better, the cache is not clean, there will always be some inexplicable little errors after setting up, and it will cause people to have PTSD over time
——3. Precautions
(1) During the construction of the website, do not open the cache plug-in! Otherwise, there will be unpredictable errors in the loading of the web content, either the modified content does not take effect, or the design style does not take effect.
(2) After the website is launched, open the cache plug-in first, and then turn on the CDN function.
