What Is Image SEO?
Image SEO is optimizing images on your website to make search engines quickly identify and understand them, resulting in increased visibility and ranking for your content on both search engine result pages and image result pages. Image SEO includes size, format, file names, alt-text, load time, mobile-friendliness, keywords and other factors.
Is Image SEO Optimization Necessary?
Yes, image SEO optimization is required because images account for 22.6 percent of all Google searches. Optimizing images is also a crucial part of ON-Page SEO which enhances the chance of ranking in Google images.
Images are increasingly being shown by Google in the standard search results, frequently before the regular organic results. – See how many images appear before the first website link in the results for the search keyword “ambassador new model” below.
Additionally, images can improve user engagement and interaction with your content and help divide potentially lengthy blocks of text.
Now let’s discuss more details on how to perform image SEO optimization. Here are our top 10 image SEO tips.
1) Choose the right format
There isn’t a single correct format to follow. Everything is dependent on the image you want to use and its purpose. However, you must first select the best file type before you begin adding images to your website.
Although multiple image formats are available, PNG and JPEG are the most popular for use on the web.
PNG: It delivers images of higher quality but has a larger file size.
JPEG: Image quality may be compromised, but you can change the quality setting to get a decent balance. They can be compressed into tiny sizes.
WebP: Use this if you require a better level of compression than what a JPEG or PNG can provide. It is the only image format that Firefox and Chrome both support.
SVG: Use this format for logos or icons
2) Compress your image sizes
Compressing the images does not mean that you should resize your images. The primary purpose of compressing the image is to eliminate the slow loading speed. According to an HTTP Archive report on page weight, images account for an average of 21% of the weight of the entire webpage.
The main objective of compressing the image sizes is to reduce your image sizes without compromising on their quality and improve the page load speed. Know more about how to compress your image sizes without losing quality
3) Name your image file names before uploading
According to Google’s image SEO guide, using descriptive file names is crucial. Also, Google advises hyphens rather than underscores to divide words.
Let us take an example of a dark chocolate bar with coffee beans.
When you save an image, your computer may give it the filename IMG00319.JPG, but that doesn’t tell Google what the image is.
We have to change the filename to “A-bar-of dark-chocolate-and-some-coffee-beans-on-a-white-surface.jpg” before uploading. This descriptive title will help Google show results quickly when someone types for that.
4) Write Alt Text that is SEO-Friendly
Why Alt-Text? – By using alt-text, you could tell Google what the image shows.
For Google to rank your images on Google Images, your alt text plays a crucial role. Additionally, increase the implementation score of your entire On-Page SEO.
Bad alt text: alt=”puppies”
Good alt text: alt=”golden retriever puppies,”
Better alt text: alt=”golden retriever puppies with scarves,”
Best alt-text: alt=”two golden retriever puppies with scarves image with a plain background.”
5) Create an image sitemap
You have to include images somewhere in your sitemaps. Whether you’re adding images to your existing sitemap or making a new sitemap just for images is entirely your wish.
Search engines are much more likely to crawl and index your images if you include them in a sitemap. As a result, website traffic increases. Yoast and RankMath’s plugin for WordPress includes a sitemap solution.
6) Optimize Your Page Title and Description
Ensure the keyword you use for your images exists in both places, your page title and description. Also, make sure that you have followed other on-page factors as well.
The core on-page SEO elements you use, including header tags, page content, structured data, and meta descriptions, all impact how Google ranks your images.
7) Add Image Structure Data
By adding structured data to your pages, search engines can show your images as rich results. Google claims structured data doesn’t help you rank higher, but it does enable you to have an Image Search listing that is more detailed. If your website includes recipes and you add structured data to your images, Google may also include a badge indicating that the image is a part of a recipe. Google Images support the following types of structured data:
8) Optimize for Open Graph and Twitter Cards
The use of images is a critical part of any social media strategy. In this situation, Open Graph is useful. Facebook first introduced an internet protocol (or set of guidelines) called Open Graph.
You can customize the appearance of a social media post preview using Open Graph tags. Thus, you control social media posts’ preview headlines, images, and other elements.
If you use the WordPress plugin Yoast, this feature is already built-in. If not, it won’t take much technical work.
9) Beware of copyright
Make sure there are no copyright conflicts with the image files you want to use. You run the danger of spending a lot of money on legal fees if Getty, Shutterstock, DepositFiles, or another stock photo supplier owns an image you use, and you don’t have permission to use it.
You may receive a notice under the Digital Millennium Copyright Act (DMCA) if you have violated any copyright concerns. The owner may make a DMCA Takedown request of a piece of content who discovers it on your website, and you must abide by it.

10) Leverage images as a chance to build backlinks.
If you create attractive, high-quality images, other companies might want to use them and link them to your website, affecting your ability to get traffic, leads, and clients or buyers.
You may also use such images to build your own backlink by posting them on social media and using them in other SEO off-page actions.
Image optimization should not be avoided. With improvements in voice search technology, the media is becoming increasingly important, and by following the above instructions, your entire site will benefit.
