Image Optimisation is not a choice it needs to be done when building a website…
Important factors of images
That’s the reason why you can’t optimizing your images for SEO. There are a ton of things included in an image especially when you want to optimize it for SEO. Here’s a list of some of the most important factors of optimizing images for SEO.
Let’s talk about each one of the above mentioned factors of images so you will know how to easily optimize an image for SEO.
Naming your images is important. Don’t use random image names and save it to your local computer or laptop and again upload them to your WordPress dashboard with the same image file name.
As most of the image names look unnatural. For instance, if you’re using images from your DSLR, they’ll mostly end up with names something like “DSC02512.JPG”.
As you can see, these type of image file names is not going to help either readers or search crawlers to understand what they are all about. That’s why to use proper and relevant names for each image before you upload them to your WordPress dashboard.
Image Alt text
Image alt text is extremely important and you must optimize your images by using proper alt texts for your images if you want better organic results.
Basically image alt text provides information to search crawlers about context of an image. So if you’re using appropriate keywords within your alt tags, you’ve better chances to show up for those keywords in Google image search.
It’s so important to know where to add your images within your blog posts or pages. As a rule of thumb, make sure to include at least one image for every 500 to 1000 words. That means, you can have 5 to 10 images for a 5000 word article.
We already discussed that images make your content more visually appealing. So by placing an image every now and then within your posts can break up your text to make it more readable for your audience.
It’s also important to choose relevant images for your blog posts. You simply can’t insert random images just for the sake of adding images. Make sure every image you add is highly relevant to the content you’re publishing.
Image captions are displayed right below the image. Whether you know it or not, image captions sometimes have more weight than the actual ALT tag of images.
The good thing about using image captions is that they can be read by your website visitors (unlike alt tags which can only read by search engine crawlers). Image captions describe an image, add context and more importantly, they give an idea of what your images are all about.
If you’re using WordPress, you can easily create or add caption to your images. Once the image is uploaded to your WordPress media library, you can enter all the images details such as title, alt text, and a caption of your image.
Here’s how it looks like;
Once you add the caption and alt text, simply click on the ‘Insert into post’ button to add the image to your posts.
Your image title plays a vital role. Not only it gets read by your audience when they hover on your image but it also adds more weight if you’re using proper keywords within your title.
We recommend you to create an image title that’s easy to read and also include a keyword phrase if you want to better optimize images for search engines like Google. Don’t use random titles or default file names for your images.
Did you know that larger images size leads to higher bounce rate on your website? Let us explain about it. The larger the size of an image, the longer it takes your page to load and it ultimately results in higher website bounce rates.
That’s the reason why you should always make sure to optimize your images size so they will take less space in your hosting and also don’t affect your page load times much. You can either use online tools to resize your images and upload them on to your WordPress dashboard after shrinking their sizes.
Or if you’re on WordPress, there are a few plugins that help you with resizing your images which include;
Let’s briefly talk about each one of the above mentioned image optimization SEO plugins so you can understand better about them.
WP Smush It: This is the most popular image optimization plugin for all the WordPress users as it helps you easily resize, optimize, optimise and compress all of your images from your dashboard.
There’s also a feature called lossless compression where you can shrink the size of your images without much sacrificing the overall quality. All in all, it’s a great plugin for all kinds of bloggers who want to shrink their image sizes from WordPress dashboard.
TinyPNG: This is an excellent WordPress plugin used by a lot of bloggers to compress their image sizes and with their free account, you can easily compress up to 500 images every single month. They also have a premium plan where you can compress up to 10K images.
Optimus: This is another popular image optimization SEO plugin that lets you compress all images <100Kb for free and it’s also a great alternative to WP Smush it plugin. The best thing about this plugin is that it reduces the image file size automatically and depending on the image and format, you can reduce the image size of up to 70%.
Our first recommendation is to reduce your image sizes before you upload them on your blogs. But if you’re looking to host your images elsewhere to lessen the burden on your hosting databases and provide faster experience to your website visitors, here are few recommendations for image hosting.
Use a CDN to host your images
One of the best ways to improve the overall page loading times of your website is to host your images on a CDN. A CDN (Content Delivery Network) is a system of distributed servers that deliver pages and other stuff such as videos, images etc to the users based on their geographic location.
There are several CDN options including CloudFlare CDN (which is free), MaxCDN (which is a premium CDN but offers much more features). If you’re using hosting platforms like Bluehost, they offer CloudFlare integration by default so you can easily integrate your websites with CloudFlare CDN from the control panel.
If you’re wondering about why you should use a CDN to host your images, here are few of the biggest benefits.
Did you know that you can easily make your images clickable? If you’re using WordPress, simply click on the image and choose the link option to insert a link that you want your website visitors to open when they click on your image.
Image linking is especially useful if you’re writing affiliate product reviews as you can make your images clickable by inserting affiliate links.
For example, you can easily include clickable links with banners of your affiliate products. That way, when your readers click on those banners or images, they will be directly taken to the product page which helps you get more sales.
