Google explained how to optimize images for the site
During the last hangout for webmasters Google spokesman John Mueller told how to optimize images for search engines.
One of the participants asked how the achievements of Google in the field of image recognition influenced search engine optimization. In particular, whether to optimize the image is no longer necessary or needed.
According to Mueller, in the future, the optimization may not be necessary. But now she still need.
The precise file names, alt attributes, title tags – it all helps. Subtitles under the image, the text around it, it all helps us to understand what was going on in the picture. All this is necessary. At least, at the moment
According to the author of the blog TheSEMPost Jennifer Clegg, Google will need at least another 5-10 years to recognize the non-optimized image. In the short term this situation is unlikely to change.
Therefore, search engine optimizators still need to optimize images so Google can better understand them.
