A classic case: optimizing a web page with the most correct headings (subtitles H1, H2, H3, H4 and so on), spacing the paragraphs well and studying the central keywords, the related ones, the synonyms…and then forget to pay attention to the images.
Images are a fundamental additional element for the user , who will have a clear, immediate visual context, which will keep him longer on the page ; but also for search engines , which will understand more easily what that web page is about. But Google spiders, to understand what is represented in an image, must rely on precise elements such as the title, the alt tag (or alternative text).
I don’t want to go on too long, there would be a lot to say about images. But I will limit myself to indicating a few good practices for treating the images of a website in an optimal way for onsite SEO .
What to Remember When Using Images on a Site for SEO
Image size and weight
First of all, take the image and treat it as 99 acres database it should be: scale the size, reducing it. Usually for a web page a size on the largest side between 800 and 1000px can be sufficient. Save it in Jpeg (lighter) or Png but appropriately sized. Even better if you know how to use new formats, such as WebP (which however is not visible in all browsers; you can study the subject
You can also use free programs like Image Optim for Mac or Image Resizer (entirely online), with which you can further and automatically reduce the weight of images. Also interesting is a tool similar to Image Resizer, called Compress Jpeg .
The operation is very simple: just drag & drop or upload one or more images (even massively up to 20 images at the same time) to compress and lighten the images in jpeg, png, svg, gif and even PDF format (the possibility of lightening even the heaviest PDFs is very interesting).
In reality, even more than the width or height in pixels of the images, the weight counts . For a slider, in fact, you may have to use how to make money on twitch images even over 1900px, for example, otherwise the image may appear grainy.
The weight of the image matters much more: usually, for an image normally inserted into a web page, the advice is not to exceed 100 KB ,
Rename the file to upload to the site
Rename the image in a descriptive and sensible way, also with an eye on SEO: the code that assigns the camera is not good (e.g. GP_076) , better “ pearl choker necklace ” if we are talking about that type of jewel, for example.
Title, Alt Tag, Caption and Description
Once the image is uploaded, in WordPress, Shopify and many other CMS we find Title, Alternative Text and often also Caption and Description . Let’s see how to treat them.
- Caption and Description :
- At least in WordPress, the caption esperanto leads usually appears on the page, so you’re talking directly to the user. It’s a useful text to better explain the image, summarizing what the user sees and further contextualizing.
- The description , on the other hand, at least in WordPress, is an additional element useful to the CMS itself to keep track of what the images represent in the media collection, and is therefore useless from an SEO perspective.
