Analysis of how to optimize the pictures on the website For the optimization of the website image, we need to pay attention to the following points:
1. Use jpeg pictures as much as possible. If it is an animation, then you need to use gif format. At present, there are many kinds of pictures in dynamic format, but users often need to install corresponding plug-ins. Using gif format will basically not affect the display of pictures, so it can make web pages more compatible. While using jpeg pictures, we should also pay attention to the overall capacity of the whole picture, which should not be too large, otherwise it will have a poor user experience, because users will open the website for a long time.
2. set Alt attribute. This is an important way to optimize pictures, and it is also an important way for Baidu spiders to read pictures, so this is the key content when optimizing pictures. Many webmasters may feel that they just need to write a short picture introduction at the bottom of the picture. In fact, this method can only improve the user's experience and let users know what this picture means, but for search engines, they still don't know.
At this time, it is necessary to add the corresponding code to this picture in the background of the webpage, and a short paragraph behind this code is the alt attribute of this picture, so the search engine spider can obtain relevant picture information through this short paragraph. In addition, when filling in this alt attribute, the text content must be complete, but not too long, and try to include the corresponding keywords to enhance the optimization characteristics of the picture. This helps to display this picture in Baidu's search results.
3. Make a small watermark for the picture. Although this will have a certain impact on the user experience, as long as we pay attention to the production method, such as making the watermark lighter and not covering the key elements of the picture, it will usually not bring a bad experience to the user. But after the watermark is passed, even if other websites reprint and want to erase the information of your website, the information of the picture is still not easy to erase, so it can produce good transmission weight. It will be helpful for SEO optimization of your website.
4. localize the pictures as much as possible. Don't save the pictures in an empty room on the internet, but in an empty room on the website, so that the pictures will open faster, and at the same time, they will not be affected by the internet speed or other websites, which will lead to the negative influence of the picture weight, because there may be all kinds of unhealthy pictures in those picture servers, which may have a negative impact on your website pictures.
how big is the website picture for optimization?
The image size has little influence on the optimization, but the biggest influence should be on the loading speed of the website. The loading of large images is naturally slower than that of small images.
how to optimize the website?
How to optimize the website is a general problem. Website optimization is generally divided into two aspects: on-site optimization and off-site optimization.
In order to better understand, the following are roughly introduced separately. You can trust me privately or pay attention to my follow-up articles for details.
In-site optimization (all for sales conversion)
In-site optimization refers to optimization on the basis of existing websites. It includes keyword layout, architecture layout and content update. General professional site builders will consider these aspects.
first, keyword layout: equivalent to website positioning, telling customers and search engines what the website is and what the core business is. This is very important. The content and optimization direction of the website should be carried out around these. It is generally reflected in the title of the website, which summarizes the core positioning of the website in one sentence
For example, the title of Yufei Shengda website is: professional laboratory planning, design, decoration and construction company; A simple sentence summarizes what the website does and lays out the core keywords of the website, such as laboratory decoration, laboratory design, laboratory construction and so on. All the operations of the following websites should also be optimized with this sentence.
second, architecture layout: architecture is a subdivision of website positioning. It is impossible for us to package all the businesses together and introduce them to customers, so we need to subdivide our businesses and design a separate page (commonly known as landing page) for each business. Meet the needs of customers in different businesses.
as for how to lay out a reasonable architecture, it is a technical job. From the customer's point of view, we should understand the real needs of customers, cater to their needs and give them the information they want to see.
Third, content update
Content update can be understood as value output, which updates high-quality articles every day, increases website inclusion and weight, thus improving the overall quality of the website and achieving the effect of keyword ranking.
Off-site optimization (all for drainage and potential)
If we compare the website to a small tree we planted and wait for the results, then off-site optimization is equivalent to watering and fertilizing to accelerate the results, and off-site optimization is to speed up the growth of the website.
there are many ways of off-site optimization, which can be said to be various. Generally, they are widely used as follows:
posting and leaving a link
Q&A
link exchange
In fact, in my opinion, bidding promotion and information flow are all part of off-site optimization. If you elaborate, you can probably write a book, so I won't introduce it in detail here.
