Images are a great opportunity to improve your on-page search engine optimisation.

Optimizing Images for SEO

Here are some easy ways to use the images you place on your web site for SEO (search engine optimiszation) purposes:

1. Use the Right Name

Just because your camera automatically names an image “DC00459.jpg” doesn’t mean this is the best name. The search engines have no idea what to do with that! Optimise your photo filenames by rename the file to something distinguishable like “Nikon-D90-Camera.jpg” before uploading it to your website.

Make the image name descriptive with a few of your keywords, but don’t go overboard with a 10-word title.

2. Alt Text: Always Use the Alternative

In addition to being helpful from a usability standpoint, search engines use the alt attribute field to help determine the content of the image. If the alt field is empty, search engines don’t always know the best way to interpret the image.

Most Content Management Systems easily allow you to add and edit content when adding images. If, not speak to your web designer.

3. Title Attribute Tells All

The title is what shows up when your cursor hovers over the image. Fill in the information for the title just as you would the alt attribute.

4. Keep Your Keywords Close

It seems obvious that you’d want to use your keywords in your text, but some people forget, thinking it’s enough to mention them in the title and/or the attributes above. If your blog post is about how to take landscape photos with a Nikon camera, then you should mention that phrase several times in the text of your page, and illustrate the page with a photo of a Nikon camers. The file name of the photo, as well as the alt and title attributes, should all support that keyword phrase.

SEO is mostly common sense. Think about what people would type into Google to lead them to your pages. Then use that phrase wherever you can — without overdoing it.

5. Compress Your Images

Compressing your images to the smallest possible size will decrease your page load time. Search engines (especially Google) emphasise a lot on how fast a page will load. Don’t compress them too much though – it’s a compromise between file size and download speed.
