6 Most important SEO tips for images

As a blogger, digital marketer, website owner, etc., Search Engine Optimization (SEO) is key to the success of your online business. Content that is optimized for search engines pulls organic traffic to your site and improves your revenue generation.

Previously, SEO was thought to be relevant only for written content but now, we have learnt that it is equally important to optimize your images for search engines because it improves the overall SEO of your site and helps you rank higher in search results. This post has outlined (based on research and personal experience) 6 most important SEO tips for images.

But first, should you include images in your articles?

Absolutely! Images help keep your article lively and interesting to readers. Imagine reading a 3,000-word article or a text-book without images, horrible right?

Additionally, images (chart, illustration, infographic, screen shots etc.) in your post help your readers understand you better. See this article for instance on how to claim free $25 from Blockchain, see how the images help readers to better understand and take part in the $25 giveaway. Now, imagine what the post will look like without the images to guide readers, I doubt if you’d want to read it.

Finally, using relevant images boosts your site’s overall SEO, potentially helping it rank higher in search results.

Now to the 6 Most important SEO tips for images

Tip 1: Include your keyword in the image file name

For instance, if you’re writing a blog post on microwaves and your keyword is; “microwaves” (just for illustration purposes, “microwaves” is a rather broad keyword). Your image file name should contain this keyword e.g. microwaves-for-2019.jpg. Avoid leaving it as DSC223.jpg.

Tip 2: Reduce image size to avoid slowing down your site

If your image is heavy, it will slow down your site and discourage potential site visitors from visiting. Best to reduce the image size before uploading. Photo editing software like Paint (Windows OS) or Preview (MacOS/Mac OS X) can be used to reduce image size.

Tip 3: Always include alt text to images

Alt texts are very important, it describes images to site visitors who are unable to view images e.g. visually impaired persons using a screen reader or visitors who have turned off images in their devices. Also, alt texts on your images help your images rank higher in image search results, they therefore boost your overall search ranking.

Tip 4: Always use relevant images for your posts

Use images in your blog posts but ensure that the images you include are relevant. Take a look at this post on what you don’t know about freelancing. See how the featured image portrays an obviously worn out person (most likely a freelancer) working on his laptop. It somehow carries the message of the post.

Images aren’t restricted to these kinds of stock images gotten online, relevant images also include charts, infographics, illustrations etc. Including these in your written content will help your readers to better understand your content and spend more time on your site. When readers better understand you, you become a trusted authority they can rely on and would willingly refer to for information.

Tip 5: Keep your images as close as possible to relevant text

An image with related text ranks better for the keyword you optimized it for.

Tip 6: Always include relevant captions to your images

Site visitors tend to read image captions when scanning an article. According to KissMetrics (2012), image captions are read 300% more than the body content itself. Including relevant captions will help you catch and retain the attention of your readers better.


In conclusion, a picture is truly worth a thousand words, using images makes your content more interesting and easier to understand to your readers. It also helps you in your overall site SEO. So, always ensure to take advantage of these benefits of image SEO when creating content for your site.
