Name your Image

Naming your image files is the first and important step. An image may a random name like image007.jpg, image341048.jpg. But before uploading the images, you need to name your image which is relevant to your post title. If you do not name your image and just add the caption, the image will only load as xxx.jpg in the search engine. xxx can be any random name.

Also, remember to use hyphens while naming the image.

For example, use optimize-image-SEO instead of optimizeimageseo

Reduce the file of your image

The size of the image is directly proportional to the load site of your page. It directly affects your viewers and SEO. If the load time of your page is high, people will not wait for it to load. They will just go the previous page of the search engine or close your page and open a different one which loads faster.

You may think that WordPress resizes your images. Actually, it does not. Browsers will first load large images and then resizes it. Though it is necessary to re-size the image, you should not compromise the quality of the image. You need to take care both the quality and the size of the image are taken care.

There are several tools available online to resize your images. You can use either online tool or any software to resize your images. If you have already uploaded the images without reducing the size, you can use plugin to reduce the size of the images on your site.

Alt text

This is important in SEO aspect. Alt text is the short form of alternative text.

We can recognize an image when we see it. But, for a bot, it is not possible. Therefore, it is important that you need to add alt text to your images. Almost all the search engines are only text-based. When you provide alt text for your images, it will be very helpful for them to understand the image.

When a picture loads, it will show a blank space first. Readers cannot understand what is going to appear in the blank space if there is no alt text.

Many people, for example, users with visual impairments, or people using screen readers or who have low-bandwidth connections—may not be able to see images on web pages. Descriptive alt text provides these users with important information.

Best format for writing alt text

Not so good:

<img src="puppy.jpg" alt=""/>


<img src="puppy.jpg" alt="puppy"/>


<img src="puppy.jpg" alt="Dalmatian puppy playing fetch">

To be avoided

<img src="puppy.jpg" alt="puppy dog baby
dog pup pups puppies doggies pups litter puppies dog retriever
 labrador wolfhound setter pointer puppy jack russell terrier
puppies dog food cheap dogfood puppy food"/>
