Image Optimization (Optimize Your Images For SEO)

Ahrefs did a small research in which they used a picture of a cat and guess what google already knew that it was a cat. This raises a question. Is image optimization dead?

But it is not that accurate! Look at the rear part of the research.

After that they tried another picture of butter. And the result was completely different. And the result proved that image optimization is not dead. Because, google identified it as a cheese. No doubt a piece of butter looks like a piece of cheese but still this thing proves that google is not 100% accurate in guessing what the picture is about. 

How Image Optimization Helps In Ranking

All the SEO beasts use a lot of pictures in their blogs. You can have a look at them. 

Even Dean Brain from backlinko used 95 images in a single blog post. You know why?

Because images help search engines understand your stuff better. 

Not only these images also help create interest between a visitor and your blog post.

An image has power to say what 100 words can not.

Therefore using visuals between your content is extremely necessary if you want that top spot. 

Note: Just putting visuals will not benefit you in any way but you also have to implement some proper SEO techniques.  

How Many Images Should You Use?

There is no specific answer to this question. If you think you need a picture to prove your point you should use a picture regardless of the number of pictures you have used before. 

When And Where Should You Use An Image?

Wherever you think that an image is putting value you should not hesitate to use them. 

Only place where you must upload a picture is a thumbnail. Because an attractive thumbnail can bring you thousands of new visitors. 

Do not use an image if it’s not serving any purpose because images are the biggest culprits for your site’s slow load speed.

Pictures taken from google or stock images are never a good option. 

Charts, screenshots, infographics, and graphs are the best solution for your pictures. And these can easily be created in software like canva. 

While creating an infographic, I would advise to put your brand’s logo and let people use it, this method will bring you unexpected traffic. 

They look extremely beautiful in-between the content and also look professional. 

Or if you didn’t find the idea of using infographics useful you can always use your own pictures. 

Using your own pictures taken from your camera is what many professionals do. But if you are not able to, there are plenty of websites that let you use their pictures. Naming some of them. 

  • Unsplash
  • Pexels
  • Freepik
  • Kaboompics
  • Pixabay
  • Burst

Even though these websites upload royalty free images, still please give them credits. 

But be sure not to overdo them. As I said earlier they can slow down your website’s load speed. 

What Is The Best Image Format?

It’s up to you what you want to use. Because JPG could be the best choice for some images and not really best for the others. 

If you are uploading a logo PNG is the best one otherwise I’ll suggest JPG.

The other format is GIF which I won’t recommend not only because they are expensive in size but also because using an animation between your content can distract the visitor and keep them from concentrating. 

GIFs are only good for animated logos.

Image Optimization For SEO

So, just putting up pictures here and there may not get you immediate results but image optimization can surely help you with that. 

Use alt text

Image optimization for wordpress is extremely useful so make sure to use alt text carefully. 

Alt text is shortcut for “Alternative text”. This thing helps the search engines understand your content. 

As we talked earlier if you don’t want google to misunderstand your pictures you have to use alternative text. 

Here is a small example:

Effiel-tower.jpg is better than IMG0015. 

If possible, use your focused keyword here. 

Use description

Try to be as expressive as you can while writing descriptions for images. 

Your image optimization for website will boost just by adding a description. 

Description box is another factor for making the search engine understand your content better. For suppose if you’re putting a photo of an old man eating a cake. 

Write your description something like this: old man eating cake. 

And one thing you can’t ignore is:

Image caption

When talking about image optimization for web

And be sure to use your main keyword in the description. It’ll help you rank high on the SERP’s. Also it will make it easier for the search engine to understand that the picture is related to what you’re writing. 

Image caption is useful when an image fails to load. Also, it’s another opportunity to rank higher on the result pages. 

Captions can also be useful for defining the image to your readers. Alt text or image description are invisible to your readers. Whereas the caption is not. 

You can use your keyword there too, as it will increase the amount of to rank for that keyword. 

But once again I must tell you. Please don’t do keyword stuffing. Write for the people not search engines, if you think the keyword sounds natural, go for it. 

Resize your images

Ok so putting big head pictures will just make it hard for your website to load fast. So, before you upload a picture, resize it first. 

Resizing will compress the image and it will be smaller in size, good for your data, good for your website, and also good for your hosting. 

Don’t rely on third party websites that let you keep your pictures on their servers because what happens is their servers get jam because of overload and sometimes your visitor will not be able to see your pictures. 

And they’ll be welcomed by a picture unavailable warning.

Remember the old saying

“First impression is the last impression”.

Make your blog so beautiful that if a visitor visits your site he thinks about it all day.

Do you want your visitors to have a bad first impression on your website or blog?

Of course not.

Don’t use hq pictures

Why would a person want to see a chart in high quality?

Human eye can barely see any difference between the two. 

Have a look at these pictures below:

Any difference in quality?

Nope.

Is it good for you?

Yes.
