Best Tips for SEO Image Optimization?
For every image you use on the website, follow these 13 tips to optimize them for search engines.
Use High-Quality & Page Relevant Images
It’s crucial for the user experience side of SEO. An image that’s unrelated to the page’s content will be confusing for the user, and one that’s low-quality or poorly scaled will just make your page looks unpleasant and unprofessional.Using stock photos from Unsplash or StockSnap can serve the purpose, but they’ll not necessarily help your search rankings, as other sites can often use the same images. Like the unique written content is better for SEO, it’s a wise idea to upload original images whenever possible.
How to Name Image for SEO
Before you add image on the website, take time to customize the filename. Change it to something that’s relevant to the page and includes one of your target keywords.If your web page is about the coffee product you sell, the image should be named as brand name-coffee.jpg. Most users will never see the filename, but it provides the search engines with a little more information about what’s on the page and the best keywords to associate with.
Image Alt Text SEO
Visitors may understand what an image is about, but search engine spiders still need info. Without image alt tag SEO text, it's impossible for search engines to index your image content precisely. A proper alt tag provides context and helps visually impaired viewers also.Even when images aren't loading for some reason, search engines can still read the alt text to help rank a page. Brand-relevant words can also be included to increase visibility.
Choose Right Format
For images, the best format doesn’t exist. It depends on the type of image and how you want to use it. In short, our SEO experts recommended to:
- Use JPEG for larger images or illustrations: It’ll deliver you great results in terms of clarity and colors with a relatively small file size;
- Choose PNG to keep background transparency; It’s ideal for images that give a high resolution and supports a text description too. The main downside of PNG is that it requires larger file sizes than GIF and JPG. It’s best to file format for complex pictures and those that include text;
- Apply WebP instead of JPEG and PNG: It’ll produce high-quality results with smaller file sizes. You can use tools like Sketch to convert image into WebP;
- Pick GIF for simpler images: It doesn’t support as wide of color range as JPEG or PNG, but it can be a good option for plain images. GIF supports small sizes and transparent backgrounds.
Loading time is important both for SEO and ranking. 'Quicker' site is better for user-experience and page indexing. Images can impact on loading time, especially when you upload a large image and display it really small.Therefore, resize the image to find the balance between quality and functionality. WordPress helps by automatically providing the image in the multiple sizes after upload. However, it doesn’t mean the file size is optimized as well, that’s just the image display size. Google is quite big on mobile, going as far as to create a mobile-first index. It means you need to consider mobile phones when optimizing images. By scaling down the large images, you’ll increase page speed, which is essential for mobile viewing.

Use Responsive Images
Responsive SEO img is essential for search engine optimization. If you’re using WordPress, this option is added by default from version 4.4. Images should have the srcset srcset attribute, which makes it possible to serve different image per screen width, especially useful for mobile devices.
Cookies are a small segment of data sent from a website and kept in a user’s web browser while he is visiting the website. Images also contain cookies, and this is useless since it slows down the page load and compromises the user experience.Ideally, images should be hosted under a cookieless domain. It’s pretty accurate for a mobile website where load time is higher.
With a sitemap, you provide Google with clear information about the images on the website. Automatically, you increase the possibility of showing up in Google image search, which boosts your site’s overall visibility.
Host SEO-Friendly Images
While it may be useful to host your image on a third-party website to save space, but it also includes a big risk. In case, those sites are overloaded with traffic, images could fail to load, creating a confusing experience on the website and making your brand look bad.You’ll have quicker loading, by hosting the images on your own site and using smaller image file size. Since it doesn’t slow down your web page any more than necessary.
