How to show images in search?

Question

Search Engine Optimization

In general, I don’t understand this very well, the task is one, to display images in the search.
The site is purely voluntary. Made it for announcements about homeless animals. The site works fine, but in the search I would like pictures of animals to be displayed. They are on every page. How to do it? Where to dig to be clear on this task?


What I tried:
- add an image to the alt attribute (one person suggested ...) That is, the view - added tags on the site according to the site schema.org But the images are still not displayed. <img src="animal.jpg" alt="animal.jpg">

Answer 1

1) Check if there is a ban on indexing in robots.txt
2) Are the pages on which the pictures are indexed and are the pictures added by scripts
3) In addition to alt , you need to add the title attribute
4) Try not to use the same alt on many pictures, robots may understand this as a re-optimization.
5) Also, indexing can be affected by the text adjacent to the picture and the name of the picture file (do not use Cyrillic).
6) Image formats must be .jpeg, .gif or .png. You can also use WebP, but not all browsers support it.
7) Add image url to sitemap or separate sitemap
The position of an image depends on its relevance to the query and on the content of the text on the page. The success of the SEO of the site itself does not affect the position of the images in the search results. On average, sitemap images are indexed for about 5 days.

Answer 2

Such a picture is generated automatically based on the availability of suitable pictures on the site, while many other factors are taken into account, including, for example, the presence of a picture on Ya. Pictures.
There is no way to manually influence the appearance of the image in the search results; no need to specifically prescribe the picture using micro-markup.
