I. What's a photoalt attribute
Photo alt properties, all known as photo replace text properties, are an attribute of the picture label in HTML languages. It is used to describe the contents of the picture, which is displayed when the picture is not visible. For the search engine, photo alt properties are an important basis for judging the content。
In the case of 100 degrees, the 100 degrees spider rarely picks pictures when he climbs over the web site and articles, but the 100 degrees seo optimization takes a certain amount of word density. So in order to enhance the effects of 100 degree seos, we need to add an alt attribute to the picture, give the picture a textual description, and insert a keyword in the middle, which increases the relevance of articles/websites and keywords, and thus the effect of 100 degree seos。
Ii. Why add a photo alt attribute
1. Increasing the ranking of search engines
According to official documents, photo alt properties are an important factor in the optimization of the 100 degree photo search. Images that add the att properties are more easily recorded at 100 degrees, thereby increasing the ranking of web pages in search results. For example, on websites that sell mechanical devices, the insertion of keywords on the product pages is not much, and generally only in the name. So the keyword isn't relevant enough? Thus, adding an att attribute to the image on the product model would be tantamount to re-planting the product type keyword, and the site's ranking in the 100-degree photo search would be significantly higher, bringing more traffic to the site。
2. Improving website accessibility
Photoalt properties can provide these users with a description of their content and improve the accessibility of the website, which is also a way to enhance user experience。
3. Improved user experience and increased number of hits
When a picture cannot be shown, the user can see the descriptive text in the alt properties, which helps the user to understand the picture content and enhance the user experience. If you fail to do so, not only will it take a lot of time for the users to wait for the pictures to be loaded, but you will not lose this part of the users if you are not patient enough to jump out of the site
Optimizing the alt properties also increases the number of hits in the search results. A news site, for example, conducted an a/b test of an article on “iphone 16” published. Before optimization, the article does not add an alt attribute to the picture; after optimization, a descriptive alt attribute is added to the picture. The results show an increase of 15 per cent in the number of hits on articles after optimization。
Iii. How to add graphic alt attributes
1. Ensure that all images have alt properties
Ensuring that all images on the site have an att attribute, which is the most basic requirement when we build a station/upload and when uploading a picture。
2. Descriptive alt properties
In optimising the alt properties, text that is descriptive and contains keywords should be used as much as possible. The following are some of the recommendations for reptile seo optimization:
(1) simplicity: avoid excessive description and try to express the main elements of the picture in a short language。
(2) contains keywords: the incorporation of keywords into the att properties contributes to the ranking of pictures in the search engine。
(3) avoid multiplicity of keywords: do not pile keywords in order to improve ranking, which would affect user experience and even be punished by search engines。
For example, in optimising the image alt properties, a medical device sets the photo alt properties of a bronchial model as "bronching, medical teaching, silicone model." this description is both concise and contains keywords that help to improve the ranking of pictures in the search engine。
Avoiding the use of terms such as “photo”, “photo”
Avoid the use of terms such as “photograms” and “photograms” in the att properties as they are not meaningful for search engines and users. The alt attribute is not a sentence, but the alt attribute of several words is also possible。
4. Appropriate use of empty alt properties
For some decorative pictures, such as background maps, partition lines, you can set empty alt properties (i. E. Alt="). This allows screen readers to skip these images and improve the accessibility of the website. It's best for pictures with a certain amount of information to add the alt properties, not to bother, until the seo optimizes, you know how important this is。
Optimizing image alt properties is an indispensible link in 100 degrees seo. By adding appropriate alt attributes to the picture, the ranking of the web page in the search engine can be improved, the accessibility of the site can be improved, and the number of hits by users can be increased. In practice, we have to follow the principles of simplicity, descriptiveity and avoiding stacking of keywords, and add appropriate alt properties to the picture.
