When I talk about search engine optimisation, I tend to focus on text. Words. I think of Google as a text processing engine. However, today I want to talk about
optimising images for search.Google, of course, offers the ability to search for images, and it can be a highly valuable way of driving visitors to your website.
Looking at my own statistics, I can see
images.google.co.uk is driving nearly 20% of the referral visitors to my website. And one image on my site in particular, a
Sunday Times logo, is driving a large volume of visitors.
My assumption is that if your images are contained in a page of content that is highly relevant, then you can convert visitors to customers on your website. And hence this blog is an experiment in optimising an image for the phrase "optimising images" and I'm going to wait and see what happens in the search engine results.
So, what steps do you need to take to optimise your images for search?
First, check to see what images from your site that Google is already indexing. Go to Google's image search and in the search box type in
site:www.yourdomain.co.uk. Google will display all the images in the index:

Optimising images for search follows many of the standard steps for optimising content on any of your web pages:
Give your image a keyword rich file name. Consider putting dashes between the keywords in the file name. Notice the image at the top of this posting is

Use the ALT tags correctly. That means using descriptive text in the ALT tag, that will contain the key phrase you are optimising for.
Embed the image in a relevant web page. Place keyword rich text immediately before and after the image, putting the image into context on the page. Indeed, the entire page should be optimised for the phrase the image is targeting.
Create internal and external links to the image, again with keyword rich anchor text in the links.
Enable Google Image Search in your Webmaster Central account. Google Webmaster Central gives you a wealth of valuable information about your site, and one setting is to enable Google image search on your website.
Include keywords in your image. Include labels in your image to describe the components or what the image is. Folk using Google Labeler (
see below) are likely to respond to the words in the image.
Participate in Google Labeler.
Google Labeler is a service on Google where you add labels (or keywords) to images on the web. It takes the format of a game: it pairs you up randomly with somebody else playing the game and you match each others keywords to describe each image. Match each others' keywords, and you get points. Curiously addictive, I'd recommend you give it a go.
I'll keep you posted to see how well this image does, or does not, rank...
