SEO Benefits from using images in your content

  1. They make your content more interesting and visitors are more likely to actually read your article. Content with relevant images gets more views than content without images.
  2. Your readers are more likely to share a page with images in social media and the shared post has more chances of getting more social media attention than plain text posts.
  3. They make it easier for you to explain a concept.
  4. It’s another easy way to enforce your SEO by giving search engines the right signals on what your content is about through images.
  5. Your images can rank higher in Google Image Search and get more traffic to your website.

How to Optimize Your Images for Search Engines

To SEO optimize your content there are several elements to keep look on when using images. Let’s see how to optimize your images.

1. Optimize the Image Filename

The first thing to check is the name of the image, before uploading it on your website.

Image Filenames should be informative and accurately describes the image.

When you purchase or take a photo using your phone, they usually have names like DC0001IMG.jpg (or similar)  and that do not make any sense.

Instead, you should rename your image to a more meaningful name i.e. “SAMSUNG-s10-rear-view.jpg” or “link-building-guidelines.png”.

The filename must describe the image in the least number of words possible.

2. Optimize the Image file size

As a general rule of thumb, the smaller the image size is (in bytes) the better.

Large images take a long time to load and this can give a negative impact on user experience especially for mobile users.

Use image optimization tools to reduce the file size of an image without losing its quality.

For all the images, first, open them in Pixelmator (similar to Photoshop), resize them and then export them in png or jpg.

Optimize their file size with image option. This will help you reduce the file size without affecting the quality.

3. Use Responsive images

Since version 4.4, there is local support for receptive images in WordPress.

This means that when you upload an image to your pages or posts, WordPress will create a number of smaller images in different sizes and will automatically fetch those to users depending on the device they are using.

If you don’t have an account on WordPress, you can implement responsive images using CSS. 

Let’s take an example of how responsive images work:

You have uploaded an image of size (1000×600) to your post. The file size of the image is 100KB. When users view your page on mobile, they won’t have to download this image and waste their bandwidth but WordPress will automatically show users an image that is 320×200 in size and only 15KB.

The result is less bandwidth and faster loading speeds.

4. Optimize the Image Alt Text

Search engine crawlers are not so good in understanding what an image is about and although they are getting better year by year on image recognition, they still need the help of the ALT Text. Alt text is an important element for image SEO.

5.Optimize the Image Caption and Title

Besides the ALT text, search engines can use the image title and caption to better understand the subject matter of your image, so it is necessary to provide them with these values.

6. Optimize Image Placement

You can position your images anywhere you want in the page but if you want a particular image to be taken into account by the search engines as an important image of your content (maybe it’s a custom image you did that is unique, original and useful), then you need to add it closer to the top with the relevant alt text, image title and caption.

7. Don’t add Important Text Inside an Image

Avoid putting up text in your images it is important for users to read. Embedded text is hard to read by both search engines as well as users. To describe your image to the users use the caption. 

8. Add Structured Data (Image Schema)

Schemas help search engines understand the content of a page better. Google can then display your images as rich results and drive more traffic to your website.

9. Add Open graph meta tags

Open Graph is a protocol introduced by Facebook. Open graph tags allow you to specify which image Facebook (and other social networks) will use when users click the SHARE or LIKE buttons from your website.

When you have a page with more than one image, you can use the log: image tags to tell FB which image to use.

The best way to add open graph protocol support to your WordPress website is to install the Yoast SEO Plugin.

10. Use an Image Sitemap

XML Sitemap is like a blueprint for your house and each web page was a room, your XML Sitemap would be a blueprint—making it easy for Google,to quickly and easily find all the rooms within your house. XML Sitemaps are important for SEO because they make it easier for Google to find your site’s pages—this is important because Google ranks web PAGES, not just websites, for Image SEO purposes you can further enrich your sitemap to provide information about your images or use a dedicated image sitemap.

11. Avoid having images and no text

Don’t forget that search engines cannot read the text if it is embedded in an image so for maximum SEO avoid having pages full of images and no text.
