One of the pieces of the puzzle for good on page optimisation is ensuring your images are setup correctly. Not only do the search engines pay attention to images and what they mean, but they also create a much better user experience. Normally when web developers discuss optimisation they generally are only thinking about reducing the size of the image faster page loading and less demand on resources. However there are a number of other tasks that should be completed that will help performance and provide more detail for the search engines to extract.
Reducing the size of images on your site is first place to start. There are a number of plugins that you can install if your site is on the WordPress platform. Two of the best in our experience are EWWW Image Optimiser and WP Smush. Both are really simple to use and can reduce the size of images in bulk. If you don’t use wordpress, or want to check, simple us the Google Page Insights page. Simply add you site and hit Analyze. It will bring back a range of issues with the site, including a section for optimisation images. To reduce the size of the images, a simple method is to use and online such as https://tinyjpg.com or http://tinypng.com. You can reduce the size of the image as much as you like. Just be aware the reducing image size will also reduce quality, so you need to find a balance that works for your site. Simple download the new resized image and then re-upload to your site.
Another aspect that many web developers either don’t do, or don’t get right is the image tags. If you’re using WordPress, it’s simple to add the tags, that will include URL, Title, Caption, Alt Text, and Description. While filling in all the tags is recommended, at the very least you should at a title and alt tag to all images. Further to that, it’s also very important that you don’t use the same title and alt tag. This will ensure the image tags are not over optimised, but also it will help the search engines rank the page for variations of terms.
Geo Location Tags
Another aspect that is missed by developers is the geo location tagging of pictures. This can be particularly important for pages or websites that are specific to a location, such as a local business. Up until recently it was very easy to do with Googles Picasa tool, however they have discontinued this platform. It’s still simple to do by using online tools such as www.geotagmypic.com. You can either download the app for your mobile device or use the online tool.
Once downloaded to your machine you can check the GPS data has been added as per below:
Adding schema is beyond the scope of this post, and requires and in depth discussion on what it is and how to use it on a site. However images can also have schema data added to them, and there is also an image and logo schema type that can be added to web pages. This provides even more information to the search engines on relevancy of a particular page. This will be a post I will add in the future.
Ensuring you follow the simple guideline above for all the images on your site will greatly enhance the relevancy and performance of any web page and should be part of your overall SEO strategy. It takes a few extra minutes, but rankings and traffic will almost always increase if you optimise your images correctly.
