Although Google's algorithm is very powerful, as to whether the crawler can distinguish the text information in the picture, Google's trend analyst Gary Illyes gave a "no" response to this question on his Twitter.
In order to convey information and beauty, most websites use many pictures. How should these pictures be optimized to facilitate website ranking? We can start from the following three points:
1. Alt and Title tags
The notation of these two tags is very simple and can be written together in the tag of the html picture.
2. Meaningful file name
For example, if you search for a car of a certain brand and model on Google, on the image search results page, you will find that the file names of many images contain the keywords you searched for. Think about it from another angle, that is, you can use pictures to rank the card position of the keyword, maybe some customers find you from the picture search results! So remember to upload it next time without changing the name, or you will miss another opportunity to expose your keywords.
In addition, many products now provide product images from various angles so that users can see more clearly. Don’t forget to distinguish the file names of these pictures. You can add descriptions such as " _Overview ", " _Neckline Recent Photos ", "_Front Seat Interior" after the original names . *Alt and Title tags also recommend this!
3. Optimize file size
Every second of waiting time represents the loss of customers, so it is recommended not to directly throw large-size pictures on the website to compress the program, which will greatly increase the processing time of the website. The most common software Phtoshop, when exporting files, you can choose whether your image is for "website use", and the software will automatically save you as a smaller image. Generally, it is recommended that the image size should not exceed 70KB, of course, if it is a full version The Banner is an exception.
Beautiful pictures help attract customers’ attention, but don’t let pictures drag your website down because of negligent settings! Quickly check whether the pictures on your website have been optimized for these three points, and let them contribute to your SEO!
