Contemplate the last time you transferred a picture to your site. Odds are good that you downloaded it from a stock photography webpage, transferred it to the backend of your website, and afterward embedded it to the page.
This makes a brilliant illustration of picture improvement, isn’t that so? Not exactly.
You’ve added a goliath bowling ball weight to your site that is dialing back the page speed. What’s more, web search tools can’t peruse your pictures without alt text.
We should change that.
More than 20% of all U.S. web look occur on Google Images, as per 2018 information from Jumpshot.
Search engine optimization beginners and experts the same realize that upgrading pictures for your site is famously worth the time spent.
Dan Morgan at WebSpection got one of his photographs to rank #1 in Google Images for “best individual in Cardiff” in under four days by enhancing his picture.
What’s more, Robbie Richards created 150,732 visits by adding picture alt labels, packing pictures, and a couple of other SEO stunts.
Without legitimate picture enhancement, you’re squandering a significant SEO resource.
It resembles the web search tools that are parting with Oreos and milk for nothing. In any case, you just take the Oreo. When as a general rule, the Oreo is way better dunked in milk.
Picture improvement makes many benefits, for example, better client experience, quicker page load times, and extra positioning freedoms. Also, it’s turning into an inexorably more significant job.
Without proper image optimization, you’re wasting a valuable SEO asset.
It’s like the search engines are giving away Oreos and milk for free. But, you only take the Oreo. When in reality, the Oreo is way better dunked in milk.
Image optimization creates many advantages such as better user experience, faster page load times, and additional ranking opportunities. And, it’s becoming an increasingly more important role.
As Matt Southern pointed out, Gary Illyes’ statement on image search in a recent Reddit chat:
“We simply know that media search is way too ignored for what it’s capable doing for publishers so we’re throwing more engineers at it as well as more outreach.”
But which factors are most important to ensure your images are findable and don’t slow down your site?
Here are 11 important image optimization tips you need to know.
Tip 1. Choose the Right Format
Decoding all the various image formats can feel like your first time ordering at Taco Bell. But, before you can start adding images to your site, you want to make sure you’ve chosen the best file type.
While there are many image formats to choose from, PNG and JPEG are the most common for the web.
- PNG: Produces better quality images, but comes with a larger file size.
- JPEG: You may lose image quality, but you can adjust the quality level to find a good balance.
- WebP: Choose lossless or lossy compression using this, the only image format supported by both Chrome and Firefox.
For me, PNG is the unsung hero of image formatting. Typically, I only use JPEGs for bigger, more visual images taken by a true photographer. But, for my daily use, PNG is the way to go.
Tip 2. Compress Your Images
Yep, hell hath no fury like a bloated web page after uploading an image that’s not compressed.
Search engines will look at your web page like you might look at a big vat of Crisco: You can’t seriously be considering putting that on you your website, right?
According to HTTP Archive, images make up on average 21% of a total webpage’s weight.
That’s why I highly recommend compressing your images before uploading them to your site. You can do this in Photoshop or you can use a tool like TinyPNG. TingPNG also has a WordPress plugin you can use too.
However, I prefer WP Smush as my WordPress plugin. It reduces the image file size without removing the quality. Whatever plugin you use, make sure to find one that compresses the images externally on their servers. It reduces the load on your own site.
Or, take it a step further and use an image CDN that detects the device and optimizes the image prior to delivery. Cloudinary and Imgix are two options to try out.
Increasingly.com improved website speed by 33% / 2 seconds by compressing images.
I mean, there’s just something sexy about faster page speed when after you compress your images.
If you’re unsure how your images are affecting your page speed, I recommend using Google’s PageSpeed Insights tool.
Tip 3. Create Unique Images
You want your photos to pop on your site. If you fill your website with stock imagery, you’ll look unoriginal – like thousands of other sites that don’t stand out.
Too many websites are cluttered with the same generic stock photos.
Think about a corporate website, a consulting firm, a business that prides itself on customer service. All these websites use virtually the same-looking stock image of a businessman smiling.
I’m sure you’ve seen one that looks like this:
While you may have your stock images perfectly optimized, they won’t have the same impact or potential SEO benefits as an original, high-quality image.
The more original pictures you have, the better experience for the user and the better your odds are of ranking on relevant searches.
Keep in mind that large images are more likely to be featured in Google Discover. As Google recommends in its Advanced SEO resource, “Large images need to be at least 1200 px wide and enabled by the
max-image-preview:large the setting, or by using AMP.” Do not use your logo as the image.

Tip 4. Beware of Copyright
Regardless of the image files, you choose to use, make sure there’s no copyright conflict.
If Getty, Shutterstock, DepositFiles, or some other stock photo provider owns an image you use, and you don’t have a license to use it, then you’re risking an expensive lawsuit.
Under the Digital Millennium Copyright Act (DMCA), you could be issued a notice if you have violated any copyright issues. If the owner of a piece of content sees their content on your website, they can issue a DMCA Takedown which you must comply with.
Google Images allows you to filter results based on those available for reuse. And, Mindy Weinstein shares 41 different websites to find free images.
Tip 5. Customize Image File Names
When it comes to SEO, creating descriptive, keyword-rich file names is absolutely crucial.
Not customizing your image file name is like getting a burrito with nothing in it. It just plain sucks.
Image file names alert Google and other search engine crawlers as to the subject matter of the image.
Typically, file names will look like “IMG_722019” or something similar. That’s like ordering from a menu in a different language. It doesn’t help Google.
Change the file name from the default to help the search engines understand your image and improve your SEO value.
This involves a bit of work, depending on how extensive your media library is, but changing the default image name is always a good idea. Let’s take this image of chocolate for example:
I could name it simply “chocolate” but if you sell chocolate on your website, potentially every image can be named “chocolate-1,” “chocolate-2,” and so on.
I named this image “dark-chocolate-coffee” to let users and search engines understand the image.
Tip 6. Write SEO-Friendly Alt Text
Alt tags are a text alternative to images when a browser can’t properly render them. Similar to the title, the alt attribute is used to describe the contents of an image file.
When the image won’t load, you’ll get an image box with the alt tag present in the top left corner. Make sure they fit with the image and make the picture relevant.
Paying attention to alt tags is also beneficial to the overall on-page SEO strategy. You want to make sure that all other optimization areas are in place, but if the image fails to load for any reason, users will see what the image is supposed to be.
Plus, adding appropriate alt tags to the images on your website can help your website achieve better rankings in the search engines by associating keywords with images. Even Google has remarked on the value of alt text in images.
It provides Google with useful information about the subject matter of the image. We use this information to help determine the best image to return for a user’s query.
Alt text is required under the American Disabilities Act for individuals who are unable to view images themselves. A descriptive alt text can alert users to exactly what is in the photo. For example, say you have a picture of chocolate on your website.
The alt text could read:
<img src=”chocolate-1.jpg” alt=”chocolate”/>
However, a better alternative text that describes the image would read:
<img src=”chocolate-1.jpg” alt=”dark chocolate coffee flavored bar”/>
Alt-text is viewable in the cached text version of the page, aiding in its benefit to both users and the search engines. For further SEO value, the alt text can act as the anchor text of an internal link when the image links to a different page on the site.
Tip 7. Think About the Image File Structure
In 2018, Google updated its Image Guidelines. One of the major updates they revealed was that they use the file path and file name to rank images.BELOW
Repeat: The file path and file name are an actual ranking factor.
For example, if you’re an eCommerce brand with multiple products, instead of placing all your product images into a generic /media/ folder, I would recommend structuring your subfolders to more category-related topics like /shorts/ or /denim/.
Tip 8. Make Your Page Title & Description
Google also revealed that it uses your page title and description as part of its image search algorithm.
The Google support page states:
“Google Images automatically generates a title and snippet to best explain each result and how it relates to the user query… We use a number of different sources for this information, including descriptive information in the title, and meta tags.”
All of your basic on-page SEO factors like metadata, header tags, copy on the page, structured data, etc. affects the way Google ranks your images.
It’s like putting all your toppings on your burrito. It tastes way better with guac. So, make sure to add the guac for improving image rankings. BELOW
Tip 9. Define Your Dimensions
If you’re using AMP or PWAs, you are required to define your image dimensions in the source code.
However, if you’re not using either, it’s still a best practice to define the width and height. It provides a better user experience.
Plus, it allows the browsers to size the image before the CSS is loaded. This stops the page from jumping when it loads.
Image dimension attributes are also important for preventing Cumulative Layout Shift (CLS) issues that can interfere with your Core Web Vitals optimization.
Making sure that you include width and height attributes for every image and video element is key.
This tells the browser how much space to allocate for the resource and prevents that annoying content-shifting that lowers your CLS score. Learn more here.
Tip 10. Make Your Images Mobile-Friendly
Oh, mobile SEO. At its worst, it can give you a high bounce rate and low conversions. But, at its best, it can give you more ranking power and better user engagement.A
Problem is, how do you optimize your images for the mobile-first index?
You create responsive images. This means the image will scale with the size of the site whether the user is using desktop or mobile. It adjusts to the size of the device.
Mozilla offers a comprehensive on using the
sizes attributes to provide the browser additional source images, enabling the display of identical image content resized for the device.
It is important to format this with a different part of the attribute value on each line, as demonstrated in this example from their resource:
<img srcset="elva-fairy-480w.jpg 480w,
sizes="(max-width: 600px) 480px,
alt="Elva dressed as a fairy">
