The only image SEO guide you’ll ever need

Image SEO is something underrated that’s in fact simple and when done right can lead to some unexpected traffic surge.

There are a bunch of rules you have to follow every time you use an image to ensure that you’re increasing your chances at SEO.

Here are the most important of them:


You’ll have to name each image file you use appropriately to what it shows, this will help you rank in the “images” section in Google and hopefully get some traffic from there


You can put lots of different name variations on this pic but the correct one would be a descriptive one. Something along the lines of: “black wooden table” should work well.

Again, you have to only change the name of the file before you upload it, nothing else.

All you need

2. Alt text (Alternative text)

Here basically you have to write what is happening in the picture. It helps Google contextualize what is on the image. Using the picture above as an example alternative text should be something along the lines of “black table made of wood sitting in the middle of the room”.

4. Resize your images

Most images you’ll find on websites for stock images are way too big and you’ll have to resize them before uploading. You can use tools like:

Or you can ask a designer to give you a hand with this. It’s easier than it seems, trust me. You can try making the image 50% or even 75% smaller and see how it looks. If it’s pixelated then you’ve probably made it too small.

5. Compress images

Now compressing images is basically reducing the file size of an image. The goal here is to reduce the file size WITHOUT losing too much of the quality

Basically, all you have to do is just upload the picture to one of the tools below and the tool is going to do the magic itself:
