Optimizing Blog Images for SEO


You just finished writing the purrrfect piece of content for your blog. You’ve double checked your spelling, punctuation, added catchy headlines, and even formatted your content for SEO. In black and white, everything looks great. Whiskers even gave his approval with a friendly meow! But – what are you missing to encourage 80% of visitors to actually read what you have to say?

Benefits of Adding Images to Your Blog

  • Introduce your theme or story
  • Support your point
  • Connect to readers
  • Add personality and color to your blog
  • Improve your SEO (Search Engine Optimization)

In addition to formatting content, optimized images enhance a blog’s SEO value. When you add shots of Fido gnawing at his bone, your blog becomes appealing to both readers and Google. Here are 5 tips to keep in mind when optimizing images on your next blog post!

1. How Many Pictures Should I Have?

You should always add pictures to your blog – but only when it makes sense. Once you’ve chosen your favorite shot of Bubbles’ new tank to share with the fish community, think to yourself: “Will this make my post better?” Images are meant to enhance content – not take away from it!

2. Finding the Right Images

Our biggest and most important tip – stay away from Google searches! Google images return pictures that best match your search query from thousands of websites. Even though these pictures may fit your search, they don’t belong to Google. Using these pictures interfere with copyright laws, and you don’t want to steal someone’s photo!

However, if you do decide to use images on the Internet, take advantage of free stock image sources. Our go-tos are Pixabay, Unsplash, Pexels, and Stock Snap.

If you’d rather add a touch of personality to your own pictures, start horsin’ around with Canva: a fun (and free!) image editing platform. Check out this image we pulled together in less than 5 minutes with the help of Canva.

3. Include Alt Text

Since Google can’t physically “see” pictures, it relies on alt text for a description of what the image is about. In a situation where images aren’t visible to users, whether they’re visually impaired or are using a screen reader, your alt text is what’s presented to the user.

Let’s use WordPress’ format as an example. Once you upload an image to your media library, you can edit not only the alt text, but the photo’s title, caption, and description in the attachment details.

Conduct your own keyword research to dig up relevant terms that will help your images, and ultimately your website, rank in a Google search. Be sure not to fall guilty of keyword stuffing!

4. Naming Images

Before uploading pictures to your blog post, each image needs an optimized title. This hops beyond simply naming a picture of Thumper as “rabbit” or “cute rabbit”. Remember that images help your blog rank in a relevant search, so you’d want to provide specific keyword-rich titles for each picture in your blog post. Here’s an example:


blonde-netherland-dwarf-rabbit.jpg vs. rabbit.jpg

This will be a hop, skip and a jump for search engines to read, return, and rank Thumper!

5. The Correct Image Format and Size

Did you know image size impacts your blog’s loading time? In fact, 40% of users will abandon a website that takes longer than 3 seconds to load. Are you using the right image format?

There are a few types of imaging formats: JPEG (JPG), PNG, and GIF. While JPG files are best for photography, PNG and GIF formats are used when images are edited or compressed.

  • JPEG (JPG) – images formatted in a .jpg file are smaller in size, and in return load faster.
  • PNG – preserves quality as an image is compressed in size.
  • GIF – supports smaller sized animated images.

The correct image size for your blog depends on the width of your page. Most blog templates vary in content area widths, usually 600-700 px, so make sure you know the content area width to optimize a perfect image size. If you upload an image 2000 px wide and your template only supports 700 px that’s a lot of unnecessary pixel size. All that extra bloat, will end up reducing your page load time.

The next time you finish formatting your content for SEO, from proofreading headers to adding bulleted lists, make sure optimizing images is on your checklist! It’s an essential step of the editing process to ensure Google can understand and relate your blog content to audiences who are wagging their tails for what you have to say!
