Seo Text usage and images
“Try to use text instead of images to display important names, content, or links. The Google crawler doesn’t recognize text contained in images. If you must use images for textual content, consider using the ALT attribute to include a few words of descriptive text.”
– from the Google webmaster guidelines 1
Text is better than images for SEO, pagespeed, mobile, your webserver and accessibility.
Common mistakes made
This guideline exists because so many people are using text in images. You may be too, consider these examples…
- Logos – If the only place your business name is found within an image, you should consider using text somewhere for your business name
- Addresses – Your business street address should always be in text somewhere on your pages, not in an image
- Small businesses – If your homepage is basically just a big graphic, you should add text to describe your business
Text links are better understood than image links
Text is well understood by search engines, images are not. If you use images for important links on your page, they might not be understood or recognized as well as text is. One example is if your website menu has an image that displays the word “cars” instead of text that says “cars”. In that case you would need to make sure that the image has an ALT tag that says “cars”.
Example of not following this guideline
Imagine if a website about animals had a home page that only had two pictures on it for navigation. One picture of an elephant and one picture of a giraffe, linking to a page about each animal.
This might seem like a clever and pleasant way to choose which animal you want to read about, but it would not be following this guideline.
Example of following this guideline
To correct that you could have a text link under each picture that said “elephant” and “giraffe”.
One important reason for having text links in addition to images is so that your webpage is accessible to those who are blind and are unable to see image links.
Another important reason is that Googlebot cannot “see” what a picture is. Look over your website and make sure that if you are using images as links, that they also have a text link as described above.
Tip: check pages for image links using the Google guideline tool
Example of truly understanding this guideline
This example has the text links and also has added a text description under each link. A small paragraph or even just a sentence of text can really help your users and search engines understand what you site is about.
This guideline does not suggest images should not be used, it suggests that text be used to convey important names, content, and links. Notice I have used images on this page, yet this page is following the guideline. I have added accurate and descriptive alt text to my images, and I have in general written this page thinking…
Could this page be understood even if none of the images were visible?
Alt text is how you add text to describe an image in an accessible way that search engines and screen readers for blind users understand.
Alt text looks like this (from one of my images above).
Alt text is very important to your website, and can affect your ranking.

- Check your webpages for alt text usage with the free seo tool
- Follow the image best practices provided by Google.
Often for design reasons your website or menu has images in it. Even though it has a word on it it is still an image.
Any text contained in such images is unreadable to those who are blind and search engine crawlers. If search engine crawlers can not read it, search engines will not know that it is there.
The more accessible your website is to the sight impaired, the more accessible your site is to search engine crawlers.
If your business street address is displayed in an image, you should definitely also have it in text as well. Your address is a very important factor for users and search engines. Your physical location is very important.
If the name of your business is in an image conveying your logo then it is possible that you aren’t even telling search engines the name of your business. Check your pages and make sure that the name of your business appears in text in addition to your logo.
- The more accessible your website is to the sight impaired, the better it will be understood by search engine crawlers.
- Anything important to identifying your website or services should be available in text.
- Any image should have a text alternative where appropriate.
- Less images to load means faster webpages.
- Faster pages provide a better mobile experience.
