Images optimization is an essential part of the overall on-site strategy, so you should take image SEO optimization seriously, especially if visual content is the core of your marketing campaign. This is the reason website builders such as WordPress offer automatic image formatting as an integral part of their on-site optimization.
Image optimization should cover pictures on your website including the header, featured images and embedded images. Customer Success Manager of Semalt, Igor Gamanenko explains why image optimization is important for your performance.
When you optimize your images with the proper formatting and phrasing, they will show up for a related image search in a search engine. If your images have been listed on Google images searches, you will get more traffic and improve the visibility of your brand. When you optimize all your images and create high-quality content, you will see a significant growth of traffic.
If you load high-resolution images on your website, it will get slow and users will have to wait to get to the main content of your site. Low site speed means bad user experience for your visitors especially if user’s browser is downloading the image files.
Image loading issues are common even when the problem has nothing to do with your server. In such a scenario, the site visitor will read the article, but will not see any images, just some blank spots where the photos are supposed to be. When you optimize your photos by adding alt text to them, your site visitors may not see the images but can read what the photo represents after an image loading problem occurs.
How to Optimize Your Site’s Photos
Compression of the images improves the loading speed of your website. Considering that most of your visitors access your site on mobile devices, it is not necessary to load high-resolution images with the weight of megabytes. You should cut the size of your photos while maintaining decent quality. Also, format your photos for the web i.e. PNG, GIF and JPG. You can also strip the metadata of your photos to cut size even more.
When use free photos from the web or stock photography, you should change the technical titles attached to them such as numbers and long string letters, giving them short accurate descriptions of what they represent. You can also include some keywords that relate to your business if it’s in line with what’s in the photo.
Always include the alt tags that describe what’s in the image. For example, include words like “woman”, “eating” if it’s an image of a woman eating a fruit.
Also known as the alt description, the caption is what shows up when the photo is not loading. It also describes the image for Google’s search index. This option allows you to describe the image in one sentence.
Strategical aligning your images with the rest of the content is better than placing them between paragraphs.
Image optimization might not be at the top of your priorities but you should do it because of the stated benefits and it only takes a few minutes to accomplish.
