Use the Right Image File Format

The most popular image formats on the web are JPEG, PNG, WedP and GIF. Each format has its own advantages and disadvantages when it comes to SEO:

  • JPEG Format: This file type produces high-quality images with relatively small file sizes. It also supports animation, making it ideal for banners and other types of adverts.
  • PNG Format: Produces high-quality images with transparent backgrounds that are suitable for webpages. However, they tend to produce larger file sizes than JPEGs so should be used sparingly.
  • GIF Format: Best suited for simple animations or graphics with a limited number of colors (commonly used in icons). GIF files tend not to be compressed as much as JPEG or PNG files, resulting in larger file sizes.
  • WebP Format: WebP is an image format that is becoming increasingly popular among web developers due to its ability to reduce file size while maintaining a high quality image. It is both lightweight and SEO friendly, which makes it the ideal choice for sites looking to optimize their loading time. Additionally, WebP images have been proven to increase website literacy as they are easier for search engine bots to read and understand.

Benefits of WebP for SEO

Using WebP for SEO can help to improve page speed, which is a major factor in achieving higher search engine rankings. Additionally, due to its small file size, WebP images can help minimize bandwidth usage which will reduce hosting costs and reduce the amount of time users spend waiting for the page to load. Furthermore, using WebP images also facilitates faster transfer between browsers as it supports modern features such as HTTP/2 and progressive image rendering.

Whichever format you choose, make sure that your image is optimized for web use by setting the appropriate quality levels when exporting the image from Photoshop or another image editing tool. Remember that smaller files are faster to download, which is important both in terms of SEO and user experience.

Choose Descriptive File Names & Alt Text

Search engines rely on text to understand what an image is about; therefore it’s important to have descriptive filenames that accurately describe the content of the image (for example yellow-labrador-puppy-outdoors rather than simply image1234). Using natural language helps Google identify what an image contains without having to analyze its contents directly.

The same principle applies when writing alternative text (alt text) for an image – use descriptive words/phrases that explain what it depicts clearly and accurately (for example A yellow Labrador puppy sitting outside in a garden rather than just dog). Alt text should be kept brief but sufficient enough that users who can’t see the image understand what it’s about anyway – this will help improve accessibility and usability across devices too!

Reduce File Size

Larger files take longer to load on websites; therefore reducing their size can help speed up page loading times while also improving search engine rankings – especially since page loading speed is one of Google’s ranking factors! There are a few ways you can reduce an image’s size while still maintaining its quality:

Compress/resize images before uploading them onto your website – many photo editing tools have core features built in that allow you to do this quickly and easily (Adobe Photoshop provides some great options here).

Look into free online tools like TinyPNG or Compressor which enable you to compress multiple images at once without needing to download extra software.

CDN and How it Works for SEO
What is CDN?

Use an image CDN (Content Delivery Network) which runs images through an optimization process for faster loading times.

Following these steps should help you optimize images for better SEO performance, resulting in higher ranking webpages and improved user experience. Good luck!any prior knowledge about photo editing software!

Serve “optimized images” through certain CMSs such as WordPress so that users only receive scaled down versions of photos depending on their device capabilities. For example, if someone visits your website from their mobile phone then they would get an optimized version of a photo which has been specifically designed for mobile devices instead! This ensures quicker loading speeds even if there are large numbers of visitors accessing your site at once!


Optimizing images correctly can make all the difference when it comes to SEO success – from increasing page loading speeds (which affects rankings) through better user experience across multiple devices; recognizing how important good quality imagery is on websites can pay off big time over time!
