Optimize blog post images for better rankingHow To Optimize Blog Post Images

Just like you optimize the text part in a blog post for SEO, you should also optimize the images that you include.

Images, when properly optimized, can rank higher in image-based search engines and drive a good amount of free traffic to your site.

Therefore, it’s important to know the best practices, tips and guidelines for image optimization.

Here are some best practices you need to know –

1. Alt Tag

With every image that you add to a blog post or an article in WordPress, you can provide an alt text, which tells the search engines what an image is about.

It’s quite easy to ignore this important image optimization element. If you’re just starting with WordPress, you should pay instant attention to this HTML attribute. For example, the image of a kid laughing should include ‘Kid Laughing’ as alt text.

Here’s an example:

<img src=”green-shoes.jpg” alt=”Green Shoes” />

2. Optimize Image Size:

When optimizing an image in a blog post for SEO, the size of the image also matters a lot.

Large images add weight to a post and too many of such posts make the entire site heavy in turn. Large images take more time to upload, thereby increasing the load time.

If you want to avoid this issue and boost the SEO of your WordPress site, you should make sure that the images you’re using aren’t large.

If you think uploading a large size image to your WordPress site and then resizing it with the built-in image editor will do the trick, you’re wrong. The large image will upload first and then it will be reduced in size every time people open the page where it’s placed.

Therefore, you should use an image editor outside of WordPress to resize a large image and then upload the smaller version of the image to your WordPress site and use it as required.

3. Image File Name

But before you upload the image, you should do one more thing. The image should be given a proper filename, most probably containing the keywords that may rank it higher. If you spend some time search images and checking their file names on Google images, you’ll notice that the file names and the searched keywords have a match.

Therefore, make sure that the image file name too is also properly optimized while being clear and descriptive for search engines to understand quickly.

4. Image Captions

Image captions can also boost the overall SEO of your site. Search engines treat captions in the same way as headlines or subheadings. If you want to improve the SEO of your blog post, you should not forget to place a caption under each image that your use.

5. Context

When talking about blog post image optimization in WordPress, context should also be kept in mind. Where you place an image throughout the entire content of a blog post will matter. If your images are incorrectly placed (near irrelevant text), Google may have a tough time deciding upon the subject matter and the SEO may suffer.

Now that you understand how to optimize images in WordPress, you should not miss out on this opportunity to take the SEO of your blog post and your entire site to the next level.
