Image optimization includes several important factors, among which the following are the most important:

File name

This is an essential element for image optimization. A short, precise and descriptive name makes it easier for web crawlers to index your images. 

The use of keywords in the title of an image increases its relevance to a specific topic. This, in turn, helps a website's search engine ranking.

Image format

Choosing the right format is essential when optimizing an image. To do so, it is necessary to familiarize yourself with the different format types and their characteristics:

  • JPG: The standard format for digital cameras and one of the most common image formats. Not suitable for transparent backgrounds. Suitable for all other photographs.
  • PNG: This is a "lossless" format. This means that it can be saved and replicated as many times as desired without diminishing its quality. It is also an uncompressed format, recommended for images with transparent backgrounds.
  • GIF: This is an image interchange format composed of several frames that give movement to the image.
  • SWG: This file extension is for logos and icons.

Size and weight

Extremely heavy images can interfere with the loading speed of your website. Ideally, your website's image files should have a proportionate weight and size. This goes hand in hand with image quality, another extremely important aspect to consider.

In both cases we advise you to find a balance. Try to make your images to preserve the highest possible quality without being too heavy. On the other hand, if you want speed on your page, WPRocket is a good option. 

Context and relevance

It may seem a bit silly, but it is important to take into account the context that accompanies the image. For this you must be very sure of the type of content you are creating. 

An out-of-context image does not provide any relevance to the topic and may mislead users. On the other hand, the use of relevant images supports the meaning of the written content and helps to expand the information.

The Alt tag is an alternative text displayed by the browser when the image cannot be loaded correctly. Google crawlers use these tags to identify and classify a file. It is also a useful tool for visually impaired people, since it allows them to know the content of an image.

As with the file name, we recommend using keywords in this tag. In addition to the alt attribute, you can also add a caption and description to the image.

Upload your images to a CDN

CDNs are content delivery networks responsible for caching the images of a website. They help to increase the loading speed of a site through different servers.

Lazy loading gives priority to the home screen and the main content of a page. Once this is done, the other files are loaded as needed. For example: you can set this tool to load images as the user navigates through the page.
