4 Best Tips For Image Optimization:

  • Images should be perfectly matched with the content of Page:

We use the image in an article to catch the attention of users towards the article. Hence, the image used should have humor, it must appeal and relevance to the subject.

  • Use Good Quality Images:

Here, the high file size isn’t the quality which is being talked about. We are talking about the quality of the images which you will upload.

The users dislike low-quality images which they find unable to view and, they also dislike high-quality images which take a lot of time to load. Hence, we should use a good quality image with low size and with proper optimization.

We prefer JPEG images as they deliver superior quality while being a small size too.
