Create Unique Images

Copying images from some of the famous free image sources is an easy way out! However, it won’t give you much advantage. Taking pictures, resizing them, and then uploading them on the website will attract your reader the most!


If you are opting for decorative images that don’t relate to the content but are used for aesthetic purposes solely, you need to choose them wisely. Background images should be consistent in terms of pattern, color palette, and borders to give uniformity to the whole website.


Choose the Right Image Formats

Image formats


The format of the images you use on your website is of great significance. Once you have created a picture, you need to save it in the format you would use on your website. The most common of them all is the JPEG format. If your image doesn’t have a transparent background, it will work well for all kinds of images for you. However, you need to realize that some file data may get lost while compressing images in JPEG format, but it won’t be significant.


Other image formats that you can use include GIF, PNG, and TIFF. If you are looking for the best quality possible, TIFF is the format you need to opt for!


Reduce Image Size

This is an important consideration of On-Page Optimization to keep in mind. If you want to reduce the speed at which your website will load. Choosing an image size appropriate for the content you are creating while ensuring that it’s not massive enough to slow down the web pages is necessary.


While managing the image size, compressing and resizing options are your best friends. They help in maintaining the quality of the images quite efficiently.


Define Image Dimensions

Image dimensions are of great importance when it comes to optimizing them. You need to be well-equipped with the skill of using the right kinds of sizes to let it showcases maximum impact on the website. The most commonly used figures are the 1:1 and 4:3 image ratios, which appear comfortable for the content creators and consumers.


Another thing to consider while choosing the image dimensions is your WordPress theme. Most of the time, the dimensions of 700-800px work great for all WordPress themes.


Keep the Image Quality High

Low-quality images don’t appeal to the content consumers visually. If the pictures don’t attract them, they are most likely to move to another website to find answers to their queries. Hence, it is mandatory to use images that have a phenomenal quality to ensure organic traffic.


Create Mobile-Friendly Images

As a content creator, you would know that most people in today’s time consume content through their phones. Hence, you need to choose mobile-friendly images. The 70 kb image size mostly works best for websites to load efficiently on the phone.


Add Image Alt Text and Title

If the image doesn’t load on the website, the Alt text, and title, also known as the alt attributes, come to play. Simply put, the text is an alternative to the images you use on your website. They appear on your website only when the photos do not load.


In simple words, if the image loads slowly, the alt text tells the viewer what the image is about.


As Google doesn’t read images, alt tags play an important role here and tell Google what the image is about.


Add Structure Data

Structured data inform the search engine about the information that is a part of the webpage. Making it a part of your website will give it a larger reach amongst the audience, as Google images will display the best of your pictures and images as rich results. This would also have a prominent budget, ensuring more traffic flocks to your web pages with relevant information.


Create an Image Sitemap

Creating an image sitemap is one of the best SEO techniques for image optimization. Doing this aids Google in discovering images that are impossible to view otherwise. One easy way of doing that is by adding image metadata to it. You’ll have to put up the contact information and relevant licensing information. It will then appear on the image search results, giving it all the relevant details.


For example, here’s what an image sitemap looks like for two images:

<?xml version=”1.0″ encoding=”UTF-8″?>

<urlset xmlns=”″













Optimize All Images for Social Media

Most of your traffic will be using social media platforms to consume your content. Hence, you need to ensure optimizing the images for social media. For that matter, it’s a great idea to choose the horizontal shape of the picture. The aspect ratio of 16:9 will make it easier for social media users to view your images. If your focus is on Facebook, choose a square shape for your pictures, while their pixels should be around 1280*720.


Set Images to Easy Load

The faster your images load, the more interested the reader will be in coming back to your website every time he is looking for relevant content. A slow-loading web page or image irritates the reader, who is most likely to shut the tab and move to another website. This is why you need to set all your images to easy load.


For easy load to work well, resize your images, compress them accordingly, use a content delivery network and enable the browser to catch your website efficiently. Once the reader is used to your fast-loading, high-quality, right-sized images, he will not move to any other website to consume the content.
