Picture SEO As an indispensable step in website SEO optimization, it is very important. Theoretically, search engines think that pages (rich media content) with words, pictures, videos and documents can be scored. For well-known reasons, domestic websites are mostly displayed in the form of words+pictures. Today, we will talk about how to do SEO optimization for WordPress website pictures.
Old Wei found that many website pages ignored image optimization, and even did not put pictures. From the perspective of drainage, it is useless to give up a lot of image traffic. A better image SEO optimization can bring a lot of traffic to the website.
1. Picture Content Relevance
The picture should be relevant to the text around it. If you insert a picture of an electric rice cooker in the article explaining the mouse, it will naturally be wrong. If it is identified by the search engine, it will comprehensively analyze the quality of the web page based on the user's browsing time, mouse click area (hot spot), dwell time and many other data, and then give an SEO score, which will be added to the ranking later. This picture will certainly not bring the correct traffic to your website, because it is a donkey's lip rather than a horse's mouth!
2. Picture originality
Search engines can identify whether an image is original to a certain extent, and original images have great advantages. Even if the purchased pictures have copyright, it is also good. Of course, try to reduce duplication with others, and you can re process the purchased copyright pictures.
3. Picture size
As we all know, search engines are increasingly demanding on the speed of website opening. Website speed has a direct impact on SEO ranking. Baidu and Google have made it clear that pages opened for more than 3 seconds will lose their ranking opportunities. At present, it is known that the page loading time on the mobile end should be less than 2 seconds, and the PC end loading time should be less than 3 seconds.
If the website load time exceeds 3 seconds, about 50% of the visitors will be lost. Every extra second of waiting will reduce 15% of the visitors (do not challenge the patience of visitors). The image size is the most important factor in the website loading speed.
Lao Wei once met a painting website where every picture has at least 1M, and every page has more than 10 pictures of similar size, with a page size of more than a few M, which is deliberately optimized. This will seriously slow down the opening speed of the page, and it will take more than 10 seconds to open the page when accessing.
So we should control the size of the image before uploading it Tinypng online image optimization tool It should be compressed and optimized without losing too much of the original color of the picture. Lao Wei has introduced many online tools of this kind before, but unfortunately they can't be accessed later. Only tinypng can be used.
4. Picture size
Compared with text, the size of a picture is very large. If you write 1000 words, a picture may not take up more space. As the size increases, the image size will double. Therefore, we should cut the size in advance according to the content of the current page to make an appropriate size image for use.
5. Picture format
Old Wei often finds that many pictures are not in the right format. For example, a landscape photo is in png or gif format, which is much larger than jpg format. Or the format of a vector image is jpg, which is much larger than png.
It is also said that a picture is only 10 kb larger. When there are hundreds or thousands of pictures on your website, the extra size is also quite large.
The image format is not only related to the size of the image, but also to the color of the image the user sees. If you use the wrong image format, there will be color distortion and incomplete images.
Lao Wei suggested that the jpg format should be used for the pictures with rich colors; The vector graph uses png format; The dynamic chart is in gif format.
6. Picture name
The name of the picture should follow the principle of relevance mentioned above. When the user searches for keywords in the image search of the search engine, the search engine will push the images with high relevance, and the images with the same content and the same name will have more opportunities to show and be clicked.
Some websites directly use local image names as uploaded image names, such as IMG_2697 or DSC1234 by default for mobile phones/digital cameras, or QQ image 202109011520. Search engines can't recognize or know what the name means.
Lao Wei suggested that it is important to include keywords when naming pictures. For example, the name of the picture can be written as the product name: plastic products supplier in China, which is rich in meaning and carries the main keyword.
7. ALT Label
Many people do not attach importance to alt tags, or the images are copied and collected, resulting in no alt tags or irrelevant tags.
Lao Wei suggested adding alt tags to your pictures on the web page, so that your pictures are more likely to be captured, indexed and pushed by search engines. The alt tag should be consistent with the picture content and the article content. Do not scribble descriptions, nor maliciously stack keywords.
A good alt tag should not only add every image, but also write it completely. It is more perfect to use a short and concise sentence to summarize the image content, and at the same time add an article keyword (naturally, don't deliberately).
8. Add keywords around the picture
Adding keywords around images can increase the display rate of images in related keyword search, promote search engines to interpret images, increase the number of images included, and finally draw more images.
As in the previous item, it can be added but not added deliberately for the purpose of drainage. If it is excessive, it will be identified as cheating.
9. Picture editing
If your energy allows, you can add keywords and valuable descriptors to the picture, if it is helpful to users, and so on. As the saying goes, a picture is worth a thousand words. Just the right image annotation can attract visitors' attention in image search results just like the finishing touch, thus improving the click rate.
10. Picture localization
If your website pictures are collected and copied, it is recommended to localize the pictures.
Image localization can not only speed up image loading (page browsing time), but also prevent the embarrassment of remote images (poor user experience). Valuable images can also bring additional traffic.
Through the above steps, we can optimize the image in place. In addition, pay attention that optimization should not be excessive and keywords should not be stacked. This is a clich é, and it is easy to be punished by search engines.
