When it comes to ranking a website, the written content is not everything. The images that accompany each text are just as important to boost your page… if you optimize them correctly. Learn about Google Image Search SEO.
What is Google Image Search SEO?
The Google Image Search SEO (or image SEO), is the strategy dedicated to optimizing the photos of a site so that they gain visibility in search engines.
An image can be striking and quality, but it must be described so that Google recognizes it as content worthy of the top positions. Through that description (which is in the HTML code), the search engine will understand what the image and the content of the site are about.
In this way, your photos will have priority in the Google Images results and your site will access a higher rank in the search ranking.
Why optimize your images?
1. Increased organic traffic
Since Google Images takes second place in the number of online searches, you can get more visits (and potential customers) with optimized images. In other words, the more visibility on Google Images, the more organic traffic to your site.
Having good images can attract young consumers such as millennials or Gen Z since 62% of them prefer visual content over written content.
2. Improve thematic relevance
The Google search engine is a robot that “scans” the words on each page. If your images are optimized, the robot will be able to “read” them and understand what your site is about. This way you can offer it in the first place in the search results.
Google also likes content updates and much more if they reaffirm the theme of your page. You can rescue old posts, and renew them with fresh information and optimized images. There is evidence of sites that have done this, increasing their organic traffic by up to 111%
3. Help accessibility
Visually impaired people use applications and screen readers that narrate the content of a web page. If the images are optimized, they will be easy to read by the software.
For example, if you have a picture of a hamburger and its alt text says “Cheeseburger and fries”, the screen reader will say that verbatim, and the blind person will understand what you are talking about.
How to optimize images for your website?
1. Add a title, description, and caption
Every image you upload has HTML attributes. They are specific words used to adjust the function of an image in the code of your website. Among the attributes that you must fill in to optimize your photos, are the title and the description.
The title is what users will see when they hover over the image. It should not be longer than 16 characters and it is recommended that it contain keywords (separated by hyphens). For example “Christmas-tree”.
In the description and legend, you can add relevant details about the image. For example: “Giant Christmas tree in a shopping center.” The legend will be visible to users.
2. Add the alternative text (“image alt tag”)
Alt text will allow search engines to quickly crawl your image. It’s also what screen readers will read and what will give your page thematic relevance to appear in Google Images.
Basically, it is a short description of the image that must also include keywords. It’s not technically a tag, but the term “image alt tag” is used as a synonym for alt text.
Depending on how you work, you can write it directly in the HTML code, or also through the CMS of the site (if you work, for example, with WordPress).
3. Adjust the weight, dimensions, and format
Images with high loading speed improve the user experience and favor ranking. Make sure your photos are no larger than 100kb. For this, you can compress the image or convert its format to the one that works best for you.
The PNG format is useful for graphics because of its light size, while the JPEG supports high-quality photos, even if they are compressed.
Finally, try to make the dimensions of the image exact, adaptable to your site, and not excessively large.
4. Incorporate structured data into your images
We recommend you follow the official Google guide to include structured data in your images. What do you achieve with this?
- Google will show your images with a rich result and can even highlight it with an icon or badge of a recipe, product, or video.
- You will deliver fast and reliable relevant information to your prospects.
- You will generate trust among those who browse and, moreover, the indicated traffic, because whoever is looking for a tutorial will surely prefer a video, and whoever is looking for the product directly will know that the image they see is what they are looking for.
Go ahead and boost your search results by incorporating image enhancement on your website into your SEO strategy.
