It is not advisable to use any image just for the sole purpose of adding an image. The image should portray the topic of the post or webpage, or have some illustrative importance within the article The reason behind is that an image surrounded by interrelated text, ranks higher for the keyword associated with it for optimization.

3: Select the right file name
Image SEO begins with selecting the right file name for the Image. This is the first place where you can use the keyword for which you want that particular content or page to rank. Google cannot read images. Google can only read text and so in case of images it reads the text related to it starting from the name of your image file. For example, if your image is a cat with background of Eiffel tower, the file name should not be IMG-00012345.jpg, but cat-at-eiffel-tower.jpg. The main keyword would be “cat at Eiffel Tower”, as it is the main subject of the photo and that is why it should be added at the beginning of the file name.
