10 Must-Follow SEO Image Optimization Tips
- Resize the Images
"Don’t mix image size with file size"
Image size refers to image dimensions (pixels) whereas file size refers to total space needed to store the image on the server (bytes).
Having images on a website with large dimensions and high resolution can slow down your page loading speed, which is why you need to scale them in a way that does not affect the quality of the image. No one likes blurry or pixelated images, so image quality would be a top priority.
- Select Correct Compression Rate
Compression rate might sound tricky, but with the right SEO image optimization tools, it can be done easily.
Remember, compressing images excessively will not only make the file size smaller but will also degrade image quality. Furthermore, using a low compression rate will profusely increase the file size.
There is no ‘one size fits all’ solution. You should try and test various compression sizes that will not harm the image quality and file size. Also, you can test for optimization speed for the particular size selected.
- Customize File Name
A relevant file name will increase the chances of ranking on SERPs and is crucial for SEO. Thus, prior to adding an image to the website, choose a relevant name (don’t forget to add keywords) to rank in image search results.
For example, if you are uploading a beverage, you can add the name Mojito or Ice Tea. Remember, the file name is strictly for search engines, visitors will never see the file name. It gives the search engine a bit more information regarding the webpage and the keywords associated.
Pro Tip - Avoid using special characters like underscores, as search engine crawlers don't recognize it. In order to separate keywords, add hyphens.
- Consider Alt Tags
Alt tags is undoubtedly one of the most talked about SEO image optimization tips. These tags are only visible to search engines, not users.
Every image can have its own alt tag. Sometimes, when there is a weak connection, or the website is having a glitch, the search engine reads alt tags to provide you with relevant information.
Without an alt tag, it is not possible for search engine crawlers to index the image content. Moreover, a keyword targeted alt tag will provide good context to search engines and improve visibility.
- Add Image Captions
Adding relevant captions under your image will help search engine crawlers to determine the subject matter of the image. Image captions work as a pathway to ensure the image is described correctly.In addition, with image captions, you have the leverage to add a target keyword on the webpage.

- Choose the Correct File Type
For raster images, you have three choices: GIF, PNG, and JPG (JPEG).
JPG or JPEG is one of the most common file formats, as it uses small file sizes and is supported by maximum websites and search engines. For image file quality, JPG is not feasible, as it does not support transparent backgrounds.
PNG provides a high-resolution image and supports a text description, serving best for SEO. However, PNG comes with a major downside that is it requires larger file sizes than other formats. So, this is mostly used for logos and complex images with text or description.
GIF is rarely used in web pages unless necessary. GIF does not support various color ranges as compared to PNG and JPG. However, it is a good choice for simple images because of transparent backgrounds and small file sizes features.
- Use Sitemap
Sitemap helps Google to crawl the pages more accurately, increasing the chances of your image displaying on search results.The sitemap is an integral part of SEO strategy. To get noticed by search engines for video, GIF, infographics, photos, or any other visual format, you need to include them in your sitemap.
Add page URL, page description, title, URL, and licence information of your visual content.
