This article mainly introduces how to optimize the picture SEO, has a certain reference value, interested friends can refer to, I hope you can learn a lot after reading this article, the following let the editor take you to understand it.

How to make search engines better identify image content?

Can let the search engine to identify the content of the picture, the best way is to add an alt attribute, the alt attribute is equivalent to the name of the picture, so that the search engine can better identify, followed by the title tag, so that users can better view the picture, when the picture is more difficult to understand, the user's mouse over the picture will show text for interpretation.

The first step: the optimization of the picture itself

1. The size and size of the picture are fastidious:

You can take a look at the following picture, why there is a small image on the left side of the search results on some websites, largely because it is in line with the size of the image crawled by the search engine. The width-height ratio of the general image is: 121virtual 75. It is reasonable to arrange the size of the picture according to this proportion, which is convenient for the search engine to display on the left.

two。 Optimize the size of the image:

The size of a picture is generally no more than 200K. Once the size of the picture is too large, the loading speed of the web page will be too slow, which will affect the browsing experience of users and increase the bounce rate of the website.

3. Picture sharpness:

The sharpness of the picture will also affect the user's experience, if the picture is not clear, the text is all right and in vain, it will give people a sense of disorder, especially when there is important content on some pictures, the user can not see the page directly, so the picture can use PS software to control the width and height, which can not only ensure that the volume of the picture is not too large, but also ensure the clarity of the picture.

4. Whether there is someone else's watermark in the picture:

When looking for pictures on the Internet, I found that many beautiful pictures have been implanted with watermarks. When choosing pictures, we must be careful and use drawing software to remove the watermarks. If the watermark is not removed, it is easy to be branded with a crime of stealing pictures.

5. Picture optimization also talks about "originality":

It is recommended that you choose the picture is not to go to the "Baidu Pictures" to find, because Baidu pictures have been included in Baidu pictures, scarcity is not high, you can try to go to Qiantu, Taobao and other major picture platforms to look for, and look for the latest just released pictures, the originality is much higher, as we all know, search engines like fresh things, pictures are no exception.

Step 2: optimize the collocation of pictures and words

1. Optimization of alt attribute of image:

Alt attribute optimization is the most basic and most important step in image optimization. Although the author has emphasized it above, it is still emphasized here that we must fill in the alt attribute to ensure that the content of the alt is similar to that of the picture. For example, if it is a picture of a person eating, alt had better write: someone is having lunch. Of course, primary school students will do it in one sentence to describe the content in the picture, so there is no emphasis here.

two。 Title tag optimization for images:

Picture title tag optimization, the focus is to facilitate browsing users to better understand the content described in the picture, has also been emphasized above, alt tag and title tag can be used at the same time, but do not deliberately stack keywords, will affect the later inclusion of the situation.

3. Optimization of the text around the picture:

In general picture optimization, in order to increase the recognition between search engines and visitors, if necessary, you can insert some words at the bottom of the picture to explain, especially some data table pictures, which you don't understand just by looking at them. then you need to explain it under the picture. At the same time, we should also pay attention not to deliberately pile up keywords in this step, and do a good job of natural optimization.

4. The name of the picture:

With regard to the naming of the picture file, it was not intended to be written in it, because it felt too basic, but before, there have been many friends asking why the picture is not displayed. The big reason is that there is a problem with the naming of the picture. The name of the first picture cannot be in Chinese. At the same time, the name of the picture can be named with pinyin of key words. For example, a picture of a decoration effect can be named with "xiaoguotu". Increase the matching degree of keywords.

The third step: the optimization of pictures in the website

1. The picture should be uploaded locally:

Many friends in the optimization, after seeing a picture directly copied and then pasted to the website, this is easy to cause later image damage, while leaving other people's website links, so you need to save the picture locally in the upload server.

two。 To make good use of the "width, height" tag to set the width and height of the picture:

When the search engine crawls, how to judge whether the image size meets the crawling standard? The big reason is the "width, height" tag in the picture, so when setting the label, it is best not to use the default width and height, it is best to set it on this site, if you do not understand the code, you can talk to me in private and do not explain too much here.
