Seo optimizes the speed of the enterprise's website are essential for upgrading the search ranking, increasing user experience and increasing conversion rates. The following are some of the strategies and techniques to optimize the speed at which websites are loaded:
I. Optimizing web images
1. Compressed images:
- pictures are one of the main reasons for the slow loading of the site. Reduce the file size of the picture without loss of quality by using graphic compression tools (e. G. Tinypng, imageoptim)。
- use of webp format, which is faster and of higher quality than the traditional jpg or png format。
2. Select the appropriate image size:
- ensure that the image size of the upload is appropriate to display the area and avoid the use of too large a picture file。
- loading of images of appropriate sizes based on the screen resolution and width of the user device, using a responsive design。
3. Use of late loading:
- delays in loading technology allow pictures, videos and other resources on the page to be loaded when the user scrolls to the page. This reduces the number of requests for initial loading, thereby increasing the speed of page loading。
Ii. Reduction of http requests
1. Consolidation of css, js documents:
- by merging multiple css or javasThe cript file is a document that reduces the number of http requests when the page is loaded。
- tools like webpack, gulp, grunt, etc. Can help you automatically merge files。
Using css sprites:
- css sprite is a technique for combining multiple small icons into one large picture. Increases the speed of page loading by reducing the number of requests。
3. Optimization of third-party plugins:
- streamline unnecessary third-party plug-ins or codes to avoid overloading unnecessary resources。
- disable social sharing buttons, advertisements and other external scripts, if not required。
Enable browser caches
1. Configure cache strategies:
- configure browser caches to allow visitors to cache static resources (e. G. Pictures, css, js files) locally after their first visit. When the user visits again, the browser loads the resources directly from the cache, thereby accelerating the loading speed。
- sets the time of expiry of the cache in the. Htaaccess file, such as:
``apace
Expressactive on
"access plus 1 year"
````
Using cache control head:
- set up appropriate cache control headers (cache-control, etag, etc.) to indicate the resource cache strategy. For example:
``apace
Cache-control: max-age=31536,000, public
````
Iv. Enable compression (gzip or brotli)
1. Enable gzip or brotli compression:
- allowing the gzip or brotli compression can significantly reduce the size of HTML, css, js files and the time that files are transferred. Most modern browsers support these compression formats。
- compression enabled by configuration servers, for example in apache, by:
``apace
Addoutputfilterbytype deflate text/HTML text/ plain text/xml text/css application/javasCript application/json
````
V. Use of the cdn (content distribution network)
1. Deployment of cdn:
- the use of the cdn allows the distribution of static resources of the website to multiple server nodes, allowing users to access resources from the nearest server, reduce delays and speed up loading。
- common cdn providers such as cloudflare, akamai, amazon cloud front, etc。
2. Cdn cache static content:
- allowing the cdn to cache static content (e. G. Pictures, css, js files) to reduce the pressure on the source server and increase the speed of response。
Vi. Optimizing server performance
1. Selection of high performance mainframe services:
- ensure the selection of appropriate host service providers. Using ssd storage instead of traditional hdds can speed up data access。
- in the case of a high-flow enterprise website, the use of a dedicated server or a vps (virtual private server) could be considered rather than a shared host。
2. Database optimization:
- optimization of sql queries: ensure that database queries are efficient and avoid unnecessary duplication。
- database index: use of index to speed up queries, especially for large databases。
- regular clean-up and optimization of databases, removal of invalid data, re-indexing, etc。
Vii. Reducing reorientation and avoiding jumps
1. Reduction in the number of redirections:
- avoid unnecessary re-direction, as each re-direction will result in additional http requests, thus delaying the loading of pages。
2. Inspection of jump chains:
- use tools such as screaming frog to check jump chains on pages to avoid redundant redirections or chain jumps。
Optimizing the load speed of the mobile end
1. Use of responsive design:
- ensure that the website is designed in a responsive manner so that the content is automatically adjusted to the size and resolution of the screen of the different devices, avoiding loading unnecessary resources。
Optimizing mobile end-specific resources:
- optimizing the resources of the mobile end based on the equipment and network environment, such as compressed pictures, reduced js interaction, etc。
Ix. Use of performance monitoring tools
Google pageped insights:
- using the google pagespeed insights tool to analyse the speed at which the website is loaded and obtain specific suggestions for improvements。
2. Gtmetrix:
- gtmetrix provides detailed performance analysis to help you identify the reasons for the slow loading of the website and give suggestions for its optimization。
3. Webpagetest:
- webpagetest allows you to simulate the performance of different devices, browsers and web sites, helping you to optimize more precisely。
X. Periodic assessment and optimization
Continuous testing and optimization:
- conduct periodic performance tests to ensure that the speed at which the website is loaded is constantly increased. Assesses and optimizes the impact of new content or features whenever they are added。
2. A/b test:
- testing different optimization strategies through a/b to identify the most appropriate options for increasing speed。
Optimizing the speed of the website is essential for upgrading the ranking of seos and the user experience. The speed of loading an enterprise's website can be improved effectively through the rational compression of pictures, the use of caches, the use of cdns, the optimization of server performance and the reduction of re-direction. Regular use of tools for monitoring and optimization based on data feedback will eventually provide users with a faster browsing experience while also improving the ranking of the website in the search engine。
