There are very few people who don’t optimise their website for keywords because of the inherent SEO benefits. But a surprisingly small amount of people take the same care with images. Just like your text, optimising images can really pull in some extra traffic. You may not think so, because most searching is done through text, but there are some definite benefits that will help any website, struggling or otherwise. Not only that, but image optimisation is so easy, that you will only spend a few seconds on it, and what is a few seconds worth of work for 1000 extra visitors?
Sure, most people are using Google (and Bing & Yahoo) to search for text links. But there’s also been an upswing in image search engines. This isn’t just Google Images, but other search engines such as Flickr and Getty Images dedicated specifically to finding images. As this prevalence increases, you may be caught in the dust if you don’t optimise your images now. Plus, if your website makes money through selling images, this can really help you boost your traffic.
This is like your body content for a text website. The alt tag allows you to provide a description for the image, and you should make sure to add your keyword into there. By far, this is the most important aspect for optimising your image. Other methods are additional benefits and really do help, but this will have the most impact. If your keyword is “great computers” make sure you type that into the alt tag!
Make img232432x23.jpg looks kind of cool, but what does it mean? Search engines are probably going to be wondering the same thing. And if your title makes no sense, you won’t receive much traffic unless your keyword somewhat relates to “IMG.”
Just like the alt tag, make sure you include your keyword! But make sure to add an underscore as a space, so “great computers” becomes “great_computers.”
Have you ever hovered over an image on a website and a yellow box appears with a description? This is part of the image title. Make sure the title is optimized, and this is going to further increase your relevancy.
Most of the optimisation work is taken care of for the image itself, but what about the website text? Believe it or not, that actually plays a part. If your copy is all about kittens, then any image search is going to be a little confused that you don’t have your “great computers” keyword anywhere.
Optimising content is great, but the easiest way of doing this is to just place the image on a relevant page. This is not the biggest metric, and you may be able to ignore it, but if you’re in a competitive niche, don’t forego it.
When you rank a website, you send backlinks to it. Why not do the same for your image? Go to outside websites and link back to your image. It will draw some traffic from those websites, and it will increase the ranking of your image.
Be sure to optimise the anchor text, or you are shooting yourself in the foot. Just make the anchor text your keyword and you will be fine. Again, optimising the anchor text isn’t entirely needed, but it always helps.
Average Traffic Increase
This really depends on how many images you are optimising and how many times the keyword is searched for images, but there are plenty of websites making a killing on this. Image optimisation is not all that popular, so you are hitting an unknown market, and there are plenty of people searching images.
Some people get an extra 100 visitors, others get over 10,000. Just optimise and find out for yourself. However, you can be assured that it will get you better traffic.
