Image title tag to add
The title tag matches the text displayed when an Internet user hovers over the image with their mouse as a tooltip. At the moment, this field is not very important for Google in terms of indexing, but it provides additional information to the visitor during his navigation. This is not mandatory, but remember to do it on your site or blog for the convenience of your dear readers!
Correctly filled Alt (alternative text) tag
The alt tag is a short description of your image content that is displayed when the image cannot be loaded and is used as a link anchor when the image serves as a link. Although it has less impact on a page’s SEO, the “alt” attribute is taken into account by Google. On the other hand, to be referenced in Google Images it is necessary to fill in this tag.
To properly fill the “alt” attribute, it is advisable to write a short text containing the main keywords that simply and clearly characterizes the image. Here is an example: A word of advice: only fill in the “alt” tag for the images you want to see in Google Images. Exclude images that are used only for the design of the site. Excessive use of this attribute may be considered spam by Google.
The caption is essential because it gives the user information about the displayed image. A real added value to the user experience, the legend makes visual content easier to read and understand. Search engines also appreciate it because it allows them to interpret the meaning of the image. Unlike the “alt” tag, the caption is visible to the Internet user. Be sure to enter keywords that are not the same as the “alt” tag.
weight of images
We don’t think about doing it systematically, but reducing the weight of images is one of the fundamental steps in optimization. High-resolution photos should not be uploaded to your site. You will slow down your site’s loading speed dramatically. So you have to go through a tool to reduce the weight of your images, such as the online tool, Kraken.io, which I presented to you in the article on SEO tools.

BMP images should be avoided (cumbersome photos because they are not compressed). JPG is more efficient for photos, and SVG is sometimes considered by browsers.
Finally, remember to link to the page that contains the image; This is important for your SEO strategy. So write a link anchor using relevant keywords for pages that contain images.
CDN (Content Delivery Network)
CDN, without going into details, is an additional data storage location (files, videos, images, etc.). These are Web-connected computers whose function is to provide content to Internet users; In our case, these are images. CDNs have several possible functions: distributing the server’s resources (reducing costs associated with bandwidth) and reducing the loading time of images for Internet users located far from the server. Finally, to finish, check that your robots.txt file does not block the indexing of images, and we also recommend you to create an image sitemap.
Remember that optimizing your images is a step that may seem daunting at first glance, but it is essential for your SEO. Once you get the right responses, it will be an integral part of your SEO operations. The most important thing if you want to keep your site manageable is to rename your images appropriately, fill in titles and alt tags, and reduce the weight of your files.
