Whether you are scrolling through Facebook or searching through Google, one of the best ways to improve your site for SEO is to have optimized images. After all, search engines like Google offer the option to search the internet based on images, and if your site has images related to what other users are looking for, then they will favor visiting your website more. Images are a great form of content to drive viewers to your online business, so long as they manage to be high quality, fast loading, and reflect what the website is all about. Today we will be going over the fundamentals of image optimization and how it can improve your website for search engine optimization.
Optimizing an image for a website is more than just taking a picture and posting it online, there are important steps to take before you put images on your website. First off, always name your images so that it describes the image. This will allow for search engines to find your image based on the name itself. For instance, if you want to name the image file of a cat, it should contain what the image is, what type of object or place the image is referring to, and the date.
Next, you should look into adding alt text into your images when placing them into your site. Alt text will allow for programs like screen readers to read the information to a user with visual impairments. As a result, Google will favor your site based on how accessible your site is, and you import your images will help that. This will result in the image name being something like gray-cat-2017.jpg with alt text stating alt= “gray cat 2017”. However, one thing to keep in mind is whether you are writing alt text or the image’s file name is that you should only write what the image is about and not for the sake of keywording.
As for the image itself, it is important to always have a small-sized image, and we don’t mean how big the image looks. The image file size, when uploaded online, can affect how fast an image is displayed online, as it takes time for an image to be displayed on a user’s browser. The optimal file size range for images displayed on a website is below 100kb (kilobytes). In a blog article by Kissmetrics, a company focusing on optimizing websites, they state that loading times can hurt your site’s effectiveness at retaining visitors and that images affect your websites page speed. By using programs like photoshop or image optimization websites like Pixlr.com or tinypng, you can turn your images from as large a 15mb (megabytes) to 15kb.
Once you have gone through those processes and your images turn out fantastic and optimized, you will still need to make sure your image is web-worthy. Testing images before and after they have been optimized is a good way to ensure the adjustments you made have worked. Using a site like giftofspeed.com can help minimize work by optimizing multiple images from your website at once.
