It is extremely common to use images on your website. However, in the same way that’s important to choose the right images and text for the ALT tags of these because of SEO.
Why are Alt Tags Important for SEO?
In fact, the ALT Text (alternative text) is the one that describes an image to people who cannot see it (robots (Google bots), visually impaired people or even people using a browser that doesn’t display certain images), even if it also contributes to optimize image for SEO.
6 Rules You should Remember When Optimize ALT Texts
To help you have quality ALT tags for your images, here are 6 rules you should remember and follow:
1. Give a Precise Description of The Images
In ALT tag of your images, don’t just write a word to define what it represents. Our goal is that a person who cannot see the image can imagine it.
For example, an ALT “how to improve your website UX 2020” tag will be better than an ALT “website UX” tag.
2. Be Concise in Describing Images
There is actually no question of writing a novel to fill an ALT tag. Users expect an alternative text to the image, which must be at most 100 characters. Some would say it’s not much, but it is clearly enough to describe an image.

3. Include Your Keywords in ALT Tags
It is well-known that ALT tags play an important role in SEO of your images (on Google), but also of the content in which they are ranked.
So never miss the opportunity to insert keywords on which you want to be ranked in this tag.
Here an example of an optimized alt text in HTML code:
<img src="how-to-train-a-dog.jpg" alt="how to train a dog"/>
If you don’t do this, the search engines may try to interpret your images and risk placing you on the wrong keywords. You might as well take care of doing things by yourself.
4. Avoid Keywords Stuffing in ALT Tags
As we have just seen, it is relevant to place a keyword in the ALT tag, but it shouldn’t be abused.
There was a time when SEO trend was stuffed with keywords in ALT tags. In other words, the latter could look like this:
<img src="how-to-train-a-dog.jpg" alt="how to train a dog dog training tips how to train your dog not to bark"/>
Above is an example of keyword stuffing in HTML code. Know that such a practice is to be banished today.
5. Avoid The Classic Error of Logo ALT Tags
Among the most used images, we obviously include the logos of companies, associations, etc.
ALT tags of these type of image are often surprising when websites are analyzed. Very often, Logo is accompanied by an ALT tag “company logo”.
So certainly, this describes what is on the image, but it would be even better to tell user of the logo of which company it is by choosing for an alt text “company logo + name of the company”.
6. Think of ALT Tags Even for Your CTA Buttons
Just because an image represents “only” a CTA button – sometimes a simple graphic element with text written in a solid color – doesn’t mean that you have to bypass the ALT tag.
In fact, users who cannot see the visual element need to understand that it is the button where to click to perform an action. At that time, ALT texts provide them with this information.
In other words, for a button inviting to request a free quote. For example, you will have to imagine an ALT tag “request for free quote” that is simple, concise and evocative, bla..bla…
Few are the bloggers or webmasters who derive the full potential of the ALT tag from their images.
However, beyond its contribution for SEO, this tag is mainly part of a logic of improving users experiences browsing your website.
