Optimizing images for SEO

by on

First let start with what an unoptimized image is. An unoptimized image is an image that has dimensions far exceeding what is required for the space it takes up on the website (eg 5000px by 4000px instead of 500px by 400px) or an image that is far larger in size than needed (eg 2MB in size instead of 200kb which is 10x the required size). There are numerous other issues as well which we'll go through in more detail below.

One of the biggest mistakes that businesses do is upload unoptimized images to their website causing their site to:

  1. Slow down due to not resizing the image size to its proper size
  2. Prevent search engines from indexing the picture due to not having alt tags
  3. Be indexed incorrectly by choosing the wrong file name

What can you do to optimize your pictures:

Pick the appropriate file name

Photo SEO begins with the relevant file name. Naturally, this is the first place to use that keyword. Without also taking a look at the actual photo, you want Google to understand what the picture is about.

Scale for image SEO

Loading times are an important UX and also, therefore, SEO aspect. The faster the website, the easier to visit and index the web page. Photos could have a significant effect on loading times, especially when you load a large picture and show it very tiny, like making use of a 2500 × 1500 pixels image as well as showing it at 250 × 150 pixels size. The whole image will still need to be loaded. Scale the photo to the dimension you want to show it. WordPress aids by supplying the photo in several sizes after upload. Unfortunately, that does not imply the size of the file is optimized as well, that's just simply the image dimension.

Minimize data size

The next step in image SEO ought to be making sure that scaled picture is offered in the tiniest file dimension feasible. There are tools for that. Naturally, you might only export the photo and test what portion of quality is acceptable, but I choose (particularly with retina and comparable screens) to make use of 100% quality photos.

Captions

The caption of the image is the text that goes along with the image.

In 2012, KissMetric even stated that "descriptions under images are read 300% greater than the body copy itself, so not using them, or not using them correctly, indicates missing out on a chance to involve a broad range of prospective readers."

Alt text and also title text

The alt message is contributed to a photo so there will certainly be a detailed message when the picture for whatever factor can't be displayed to the site visitor.

Take these things in mind when including a picture to an article:

  • Use a pertinent image that matches your message
  • Pick the appropriate documents name for your picture
  • Make sure photo dimensions match the image size as presented
  • Lower file size for faster loading
  • Add a subtitle for simpler scanning of the page
  • Utilize a photo alt message; title text is optional


Alongside picture SEO and using photos for individual experience, images can likewise play an important function in conversion!
