In which type of webs is it a priority to optimize images for SEO?

In an ideal world, all webs would have perfectly prepared images for organic positioning. Given that the reality is different, there are sectors and types of portals in which a specific strategy for visual content will provide more value than in others.

It should also be said that there are different degrees in which to work the images at the SEO level. From simpler and more essential aspects such as the incorporation of the ALT and HTML attributes to the HTML tags of the images to more complex tasks such as the generation of a specific Sitemap for the images.

Depending on the weight of this type of visual content on our website and business, we will delve into different levels of this type of action.

That said, some of the types of websites that can benefit the most from SEO for images are:

  • E-commerce: in online stores with a large number of products, the optimization of photographs of them is essential, both for SEO and to offer a good user experience.
  • Webs of sectors oriented to design, art, etc.: in this type of webs intrinsically linked to a visual component, the quality, and optimization of images are vital.
  • Webs where the visual experience is part of the purchasing process: in sectors such as decoration, the search for images is another step in the Consumer Journey.


How to optimize images for SEO?

The main actions you can take to optimize the images of your website for SEO are:

  • Filename: include the keyword as part of the name of the image.
  • Optimize weight: especially required on websites with a high volume of traffic from mobile devices, reduce the weight of the images without affecting the quality of it.
  • Adapt the resolution of the image to the device: through the HTML attribute srcset, we can define which resolution to show according to the device through which the user accesses.
  • Choosing the right type of format: in general, JPG is the most widespread format for web images, but other forms such as PNG or GIF provide different functionalities (transparency, animations) at the risk of increasing their weight.
  • Incorporation of ALT and TITLE attributes: with a short description of the image, always adding the keyword to which we are going.
  • Footer: In English known as “Caption,” the introduction of an optimized footer can add a positive value to our SEO strategy.
  • OpenGraph Protocol: prepare the code of our pages so that in sharing them on social networks and other platforms, they show the correct image.
  • Sitemap of images: to facilitate access to all our pictures to Google, we can generate a Sitemap in XML format specific to them. We also have the possibility to associate an image to the pages of our normal Sitemap.
  • Use of structured data Schema: specifically for online stores. If we mark our products with the correct specification, including the images, through the Google Images search engine, users will be able to access the product file itself.
  • Host the images on our server: although it is not usual, there are websites where images point to other portals. We must avoid this type of practices.
  • Relevant, quality and original images: to the extent that we can, use our own photos (avoiding image banks) made by professionals.
