Website Speed
Website speed is one of the factors that influence Google’s search rankings, which is well known. However, this year, Google said that search engines only spend a fixed amount of time and resources on your website to crawl data on a daily basis, leaving it over time, so speed becomes more important.
Optimize your website speed to improve both the user experience and the amount of data that Google crawls on your site. At the same time, the speed of the website itself not only affects your ranking, but also affects the friendliness of the website.
After all, your website is slow to search engines to crawl data, and users will be affected when they use it.
And now mobile devices are so popular, many people take the phone when they take the bus and take the subway. If your website has to wait for tens of seconds for each page, it will be a matter of course. Even let them not want to visit your website again.
Website speed test tool
You can refer to the tools to help you test the speed of your website:
Google PageSpeed
Google PageSpeed is Google’s website speed optimization tool. Its benefits are easier to operate, and the information provided is simpler. You can quickly see the problems of your website. Common image compression, Gzip, and server response time. Help you detect it, even the results of both the PC version and the mobile version can be viewed together.
What are the common optimization projects in website speed optimization?
Use browser cache (cache) function
The caching function allows the user to save some of the data when he visits your website, and then he does not have to re-download the data when he visits next time, thereby improving the browsing speed of the website.
Best image optimization
The size and number of pictures is often the killer of the website speed. Obviously, you only need to use 300*300 pixels to display clear content. You have to use 600*600 pictures, although the user sees the page is indeed 300*300 pixels, which can be downloaded from the server is a 600*600 image, which will greatly affect the speed of the website.
Optimize the number of http requests
Every Javascript, CSS, and image on our web page will require the user to make one more request with the server. If you have 20 CSS, the browser must interact with the server 20 times to get all the files, so too much. CSS and Javascript will cause users to perform more than one http request when interacting with the server, which will of course greatly affect the speed of the website.
In particular, some web engineering teams are likely to generate too many CSS/Javascript due to the division of labor. It is recommended to merge CSS/Javascript as much as possible within a reasonable amount.
(Of course, this depends on the size and architecture of the site, but even if your site does require a lot of CSS/Javascript, it is recommended that you merge them as much as possible, and don’t let users execute too many http requests)
GZIP compression function
GZIP is a very common feature on web pages. It can effectively compress web resources and improve users’ download speed. GZIP is also a function that Google officially advocates for everyone to make good use of.
If your Google PageSpeed can’t be optimized to 90 points, then at least 70-80 points should be optimized. It may cost you a lot of manpower and time, but the benefits are extremely long.
