Image SEO: Best Practices and Tips for Optimization

Optimizing images for search engine optimization (SEO) is an important part of creating a successful website. Image SEO can help your site appear higher in the rankings, and it also helps to provide a better user experience

In this blog post, we will discuss image SEO: best practices and tips for optimization that every web developer, online marketer, content manager, or company owner should know. We’ll cover topics such as resizing images, optimizing file names and titles, using alt tags and captions, plus more! 

Let’s begin with our guide on optimizing your website images so you can take advantage of all the benefits associated with image SEO.

Image SEO

What is Image SEO? 

Image SEO is optimizing your images for search engines using thoughtful alt text, appropriate captions, proper file dimensions, and other techniques. Image SEO can make your content easier for search engine crawlers to understand, boosting SEO on both search and image results pages and making your site more discoverable.

Why is image SEO important?

According to Internet Live Stats, 3.5 billion Google searches are conducted daily. Google Images accounted for 22.6% of all internet searches in 2018.

Optimizing your site’s images will improve your site’s UX, load time, and rankings in regular SERPs and image searches. Image SEO is especially important for e-commerce sites, as you will almost certainly have hundreds of images. If they are properly optimized, you will retain a lot of potential traffic and rankings.

With the advancement of visual searches, such as the ability to use images to purchase products, image optimization will play an even larger role in search. Both Google and Bing use visual search; Google has Google Lens, and Bing has visual search.

Best Practices and Tips for Image Optimization

According to Jumpshot data from 2018, Google Images accounts for more than 20% of all web searches in the United States. The best tips and practices for Image optimization are listed below. 

Resize Your Images

When it comes to SEO, image size is an important factor. Images that are too large can slow down page loading speed and negatively impact user experience. To ensure your images look great on all devices, you must ensure they’re the right size for the web.

Use Photo Editing Software 

The best way to resize images is using photo editing software like Adobe Photoshop or GIMP. These programs allow you to adjust the dimensions of your image without losing quality. You should also consider reducing file size when resizing images, as this will help reduce page load time.

Consider Creating Multiple Versions

It’s important to note that different types of images require different sizes for optimal performance online. For example, product photos should be larger than thumbnails so customers can get a better view of what they’re buying before making a purchase decision. On the other hand, icons and logos should be smaller in order to fit into tight spaces on web pages without looking distorted or pixelated.

Consider creating multiple versions of each image at various sizes, so you can choose where it needs to go within your website design or layout structure (e.g., sidebar vs. full-width). This will save time later if you need an alternative version quickly for any reason – such as updating content across multiple pages with new imagery faster and more efficiently!

Use Responsive Design For Cross-Device Compatibility

Remember that most websites use responsive design these days. Their layouts automatically adjust based on device type and screen resolution; one optimized image can work perfectly across all platforms, from desktop computers to tablets and smartphones.

Compress Images To Make Them Load Faster

Image compression is an essential component of any good website optimization strategy.

Simply put, it makes your web pages load faster, which improves user experience and boosts your website’s search engine rankings.

Try Attrock’s Free Image Compression Tool, Compress JPEG, or Squoosh to compress your images effectively.

Optimize Image File Names

When optimizing images for search engine visibility, the file name is one of the most important factors. 

Give Your Image A Descriptive File Name

You must give your image a descriptive file name that includes relevant keywords so that search engines can understand what the image is about and rank it accordingly.

For example, if you have an image of a blue sweater on your website, instead of naming it “image1” or something generic like that, use something more specific such as “blue-sweater.jpg” or “mens-blue-crew-neck-sweater.jpg.” This will help search engines better identify and index your images in their results pages.

Avoid Using Special Characters 

It’s also important to avoid using special characters in your file names since some web browsers or search engines may not recognize them. Stick with hyphens (-) between words instead of underscores (_). 

Try To Keep File Names Short 

Keep your file names short but descriptive – no longer than three words if possible – and ensure all letters are lowercase for consistency across different operating systems and web browsers.

Use Alt Tags

Alt tags are an important part of optimizing images for search engine optimization (SEO). Alt tags provide a text description of the image, which can help search engines understand what the image is about. They should be descriptive, include relevant keywords, and be concise and easy to read.

When adding alt tags to your images, make sure that you use accurate descriptions that accurately describe the image’s content. Avoid using generic terms such as “image” or “photo” in your alt tag; instead, try to come up with more specific words to indicate better what is depicted in the photo. 

Additionally, it’s important to keep your alt tag length under 125 characters so that it doesn’t get cut off by search engines.

It’s also important to note that if you’re using stock photos on your website or blog posts, you should still add an appropriate alt tag, even though there may be little information about them online. This will ensure that they are indexed properly by search engines and can lead people back to your site when they do searches related to those images.

In addition to helping improve SEO rankings for images on Google Image Search results pages, proper use of alt tags can also help increase accessibility for visually impaired users who rely on screen readers or other assistive technologies to access web content. 

Finally, remember mobile devices. Many mobile browsers strip all non-essential HTML code from webpages before displaying them, including any associated ALT attributes. Therefore, make sure you optimize all of your website’s images accordingly if you want them visible across multiple platforms and devices.

Make Images Mobile Friendly

When it comes to images on your website, making them mobile-friendly is a must. Responsive design techniques can help you ensure that your images look great no matter what device they’re viewed on.

  • Scaling down the size of an image or using smaller file sizes are two ways to make sure your images look good on all devices. This will also reduce page loading times and improve user experience, as larger files take longer to load and may cause users to abandon the page before they even get a chance to see it.
  • When optimizing for mobile devices, you should also consider how text complements the image. If you have text overlaid onto an image, make sure it’s legible at different screen sizes by increasing font size or changing its color if necessary.
  • Using alt tags is another way to make sure your images are accessible across all devices. 

Making sure your images are mobile-friendly is essential for SEO success. 

Optimize the Image Title

You must use relevant keywords in your image titles so users and search engines can easily find them.

Include Keywords 

When creating a title for an image, include keywords that accurately describe what the image is about. For example, if you have an image of a laptop computer, you could use “laptop computer” as part of the title. You should also consider including other related words, such as “computer” or “notebook,” to give the image more context.

Keep Titles Concise And Descriptive 

It’s important to keep your titles concise and descriptive without being too long or wordy. Search engines may only index short titles, which means they won’t appear in searches! Aim for around 10-15 words maximum per title, and avoid using unnecessary punctuation marks like exclamation points or question marks.

Avoid Using Special Characters 

It’s also worth noting that some search engines are case-sensitive regarding titles, so try only to mix upper and lowercase letters if necessary. Also, avoid using special characters such as underscores (_) since these may cause issues with indexing.

Unique Images With Different Titles 

Ensure each page on your website has unique images with different titles; this will help ensure each page stands out from others on the same topic while providing additional SEO benefits.

Optimizing image titles helps ensure that your images are properly indexed and ranked by search engines, making it easier for users to find them. 

Include Captions

Captions provide context to the reader, help them understand what is happening in the image, and can even be used as a way to add humor or draw attention to certain elements. Captions should be short but provide enough information for readers to get the gist of what’s happening in the picture.

Include Keywords 

When it comes to SEO, captions also play an important role. Search engines use captions when indexing images to understand their relevance better and rank them in search results. This means that including relevant keywords within your caption can help improve your chances of appearing higher up in search engine rankings for those terms – potentially leading more people to view your content!

Include Hashtags 

It’s also worth noting that some social media platforms (such as Instagram) allow you to include hashtags within captions, too – this is another great way of increasing visibility for your posts by making sure they appear when users search for related topics or phrases.

Adding captions can make images more accessible for visually impaired users who rely on screen readers or other assistive technologies. These devices will read out loud whatever text has been included with an image. All necessary information must be provided here if you want everyone who visits your site/social media page/etc., regardless of ability level, to have access to all available content.

Use Unique Images

Using unique images on your website is essential for improving the user experience and helping to optimize your site for search engines. Unique images can help differentiate your content from other websites, giving it a more professional look and feel. 

They also make it easier for users to identify the content they are viewing and for search engine crawlers to index the page.

Select Relevant Image 

When selecting an image, consider how it will fit into the overall design of your website or blog post. It should be relevant to your writing and not just used as filler material. 

Additionally, avoid using stock photos that other websites have overused; instead, opt for original photographs or illustrations that reflect the message you’re trying to convey creatively.

Properly Optimize All Images 

All images must be properly optimized before uploading onto a web page or blog post to keep loading times manageable. This includes resizing them if necessary (to ensure they’re manageable) and compressing them where possible without sacrificing quality too much – both of which can be done easily with free online tools such as TinyPNG or Compressorio. 

Additionally, make sure each image has an appropriate file name and alt tag associated with it; this helps search engine crawlers understand what each image is about when indexing your site, thus improving SEO performance.

Include Text 

Finally, remember that text should complement any accompanying images rather than compete against them. This means keeping captions concise yet informative enough, so readers know exactly what each photo represents without guessing its meaning the first time.

Ensure Text Complements The Images

This means you should ensure that your text provides additional information about what’s in the image and why it’s relevant to your content.

For example, if you have an image of a laptop with a cup of coffee on top, you could include a caption such as “Take advantage of mobile working with our powerful laptops!” This gives readers more context and helps them understand why this particular image was included in your post.

It also helps search engines better understand what’s being depicted in the photo. When Google indexes an image, they look at its visual elements (like color or shape) and any associated text (like captions or titles). 

By providing descriptive text alongside your images, you can help Google better index them so they appear when people search for related topics.

In addition to helping search engines better understand your images, having descriptive text can also be beneficial from a user experience perspective. People often skim through articles quickly and only sometimes take time to read every word; having descriptive captions next to photos can help give readers more information without forcing them to slow down their reading speed too much.

Finally, adding descriptions alongside photos can also be helpful if someone has trouble seeing due to vision impairment or other disabilities. Screen-reading software will read these descriptions aloud, so users relying on this technology will still get all the information within each photo, even if they cannot see it.

Add Structured Image Data

One way to optimize your site for SEO is by adding image-structured data. Structured data helps search engines understand the content on a page and can help improve visibility in search results.

Include Specific Tags Within The HTML Code

Adding image structured data involves including specific tags within the HTML code of each page that contains images. These tags provide information about the images, such as their size, file type, title, description, and more. This allows search engines to better index the images and displays them in relevant searches.

  • “Alt Text” Or “Alt Attribute” 

The most common tag used for image structured data is “alt text” or “alt attribute,” which briefly describes what an image shows or represents when it cannot be displayed properly due to technical issues or slow loading times. 

Alt text should be concise yet descriptive enough so that users can understand what they are looking at, even if they cannot see it clearly on their device screen.

  • “Title Attribute” 

Another important tag used for image structured data is called “title attribute,” which gives additional information about an image, such as its author name or copyright details if applicable. 

It also serves as anchor text when linking from one page to another using this particular element; this increases click-through rates from organic search results pages and makes navigation easier for users who may not know where exactly they need to go next after viewing a certain page with multiple links available on it.

Use Site Maps

A site map is essential for optimizing your website’s search engine visibility. It provides a way for users to navigate through the different pages of your website easily and helps search engines crawl, index, and rank all the content on your site. Site maps can be used in two ways: 

HTML Sitemaps

HTML Sitemaps are designed to help visitors find what they need quickly by providing a list of links that lead to each page on the website. They should include important pages such as contact information, product categories, blog posts, etc. so that visitors can easily access them without having to click through multiple levels of navigation menus.

XML Sitemaps

XML Sitemaps are intended specifically for search engine crawlers and provide detailed information about each page on the website, including its URL, when it was last updated, how often it changes, and more. This allows search engines to understand better which pages are most important and relevant so they can prioritize them in their results accordingly.

FAQs About Image SEO: Best Practices and Tips for Optimization

To ensure that your images are properly optimized, use descriptive file names and alt tags to help search engines understand what the image is about. Additionally, compress the size of your images, so they don’t slow down page loading times. 

Finally, use a CDN (Content Delivery Network) to store and serve your images quickly and reliably across multiple servers worldwide. Following these steps will help you get more organic traffic from image searches and improve the overall user experience on your site.

When it comes to SEO, the best image format is usually JPEG. This is because JPEGs are highly compressed and have a small file size, which makes them faster to load on webpages. Additionally, they support high-quality images with good color accuracy and sharpness. 

PNG files can also be used for SEO purposes as they offer better transparency options than JPEGs but tend to have larger file sizes which can slow down page loading times. Ultimately, when choosing an image format for SEO purposes, it’s important to consider quality and speed to get the most out of your website’s performance.

  • Optimize page titles and meta descriptions: Page titles should include the target keyword, be descriptive, and be under 60 characters. Meta descriptions should include the target keyword, be concise (under 160 characters), and entice users to click through to your site.
  • Utilize keywords in content: Content should always contain relevant keywords related to what you’re trying to rank for in search engines. This helps search engine crawlers understand what your website is about so they can properly index it for relevant searches.
  • Build quality backlinks: Backlinks from other websites help boost a website’s ranking in SERPs as well as increase its visibility online by directing more traffic towards it from external sources such as social media platforms or industry blogs/websites. Quality backlinks are essential for SEO success since they indicate the trustworthiness and authority of a website on the web.


By following the best practices and tips for optimizing images, you can ensure that your site will be more visible to search engines and provide a better user experience. Optimizing your images properly can help improve your website’s visibility in search engine results pages (SERPs) and drive more traffic to your site. 

With these simple yet effective techniques for image SEO, you can maximize the potential of each image on your website and make sure it contributes positively to its overall success.
