Image Optimization yields many positive results with increased visibility on search engines and also improves conversions.
Use relevant names for your images
Many times when we do a site analysis, we find images with names that have nothing to do with the site, images that contain camera names or even random names.
Give appropriate names to your images, this is essential for the optimization and indexing of your project. Always use keywords in the file name that are related to the images and create long names to increase the number of words. It is good practice to always use names in lower case and separated by a hyphen.

A picture is worth a thousand words
The quality of the images added to your project has a direct and proportional impact on your users and customers, the better the treatment and optimization of images, the greater the likelihood of engagement and sharing of your content.
Sharp images look better in thumbnail versions displayed on search engines like Google and a higher chance of the click! Look for a good image bank and spend a little on professional images!
Avoid problems with copyrights (copyrights), look for an image bank with the best cost benefit and use the correct formats in their proper places. Don’t invent fashion!!
Do not abuse the dimensions and weight of the Images
The size influences the loading time, being an important positioning factor, so scale the sizes consistently in width and height so that there is no rework later.
Another very important factor is the weight of the image, it is essential to reduce the maximum without losing quality.Add title and alt text
Image title is not a determining factor for positioning, it is important to pay attention to the titles of images that are normally displayed when we hover over them with the mouse.
They can convince the user to continue browsing the website and reduce the rejection rate from searches, encouraging more clicks and indirectly influencing their placements. Another important point is that the main web page reading software for the visually impaired use the alternative description field (ALT) to explain what the image is about.
Respect your layout and organize your images
Declaring the dimensions (width x height) improves page loading without repositioning, improves the user experience and consequently makes Google very happy.
