One of the important factors influencing the user experience of the website is the speed of the site, which is most affected by the image, so that a good graphic optimization of the site can significantly increase the speed of loading the site, thereby increasing the user experience of the site, increasing its conversion rate and increasing sales。
The website optimization aims to increase the speed of access to the site, which is also an optimised content, as the site consists mainly of pictures and text。
Why do you want to optimize pictures
Pictures can create visual effects that are better than textual ones. However, a website that is too numerous or chooses its type, size and organization inappropriately can cause the site to load too slowly, thus affecting its ranking in the search engine。
The aim of graphic optimization is therefore to create a situation in which the visualization of the site is achieved with little impact on the speed of the site and a balance between its optimization and visualization。
Method for optimizing web site pictures
Test site speed. The need for photo optimization of the website presupposes that the site has a slow or poor experience due to the image. In general, websites where such problems arise, the search rankings are relatively low, even with a strong effort to optimize results。
A number of speed measurement tools allow speed measurement of the website. For example, google or 100 degree station master tools。
Determines the type of website picture. Picture types on the website include jpeg, gif and png. Different photos, suitable for exporting to different types of photographic files。
For example, the jpeg format is suitable for more colourful and complex pictures; the png file is suitable for some illustrations and for more single coloured images, including icons; the gif file needs to consider the frequency of displays and the need for circulation。
Resizes the picture. In particular, some of the images taken by one-on-one cameras are often less large in practice. It needs cutting and adjusting, and if your wordpress theme shows a picture at a resolution of 500 x 500, and your upload image resolution is 1024 x 1024, all these additional pixels will only increase the size of the file and reduce the speed of the site without real benefits。
Pictures compress. Compression is possible before uploading pictures to the website. This will also reduce the size of the document。
Compression can be divided into impairment and loss. No loss compression, before and after compression, no change in the quality of the picture. Decompression removes some additional elements from the picture。
Picture optimization tool. A number of station-building systems have graphic optimization plugins and tools that automatically optimize images, including resizeing and compression。
Fuzzy treatment. In order to balance experience while reducing the size of the web page. Fuzzy treatment is one approach. One of the strategies is to load low-quality pictures when the user opens, in a few seconds, and then show more details. The second strategy is to blur the background and parts of the picture and to reduce the size of the web-based documents, which can also have the effect of increasing loading speed。
Delay in loading. When users open a website, they need to scroll to see the rest. The delay in loading is the loading of parts that are visually touched by the user, while the loading of parts that have not been rolled by the user is delayed. That is, instead of loading all pictures at once, they are loaded according to the user's visual movement。
The role of website photo optimization:
First, user experience could be enhanced, such as a website where users can enjoy faster loading
Second, the search ranking of the site could be raised. With these two points in mind, it is worth doing the job of optimising the image of the website。
