Not optimizing the images that are uploaded to blogs and web pages is a very common SEO mistake . Most users download the stock images, upload them to WordPress or any other text editor, and publish them. Without the right optimization, images can weigh down SEO and ruin a page's loading speed.

Improving the user experience, increasing the loading speed and improving the positioning, these are some advantages of optimizing the images.

SEO experts know that image search is important for positioning, but that it is also a part largely ignored by users. Optimizing images is a part of SEO work that should not be forgotten. But what factors are most important in ensuring that images can be found and don't slow down the site? Along with these basic SEO optimization tips, here are seven other tips to optimize images you should know:

1. The correct format: It is very important to choose the correct format. For example, PNG offers better quality, but files are heavier. JPEG loses quality, but allows more flexibility.

2. Compress images: Images can represent 21% of the total weight of a web page. So it is necessary to compress the images before uploading them. There are many tools to do it like TinyPNG or WordPress plugins can be used.

3. Rename the images: To improve SEO to the maximum, the images must contain the keywords in the title. The name of the image is used so that Google spiders understand what they are seeing and know where to classify the image.

4. Add the images to the sitemap: Add the images to the sitemap or create a sitemap of the images, improves indexing. If the images are properly configured and indexed, they will drive more traffic to the page.

5. Alt texts: Alt tags are alternative texts that will be displayed when the browser cannot display the images correctly. Similar to the title, the Alt description is used to describe the contents of an image. Optimizing the Alt texts will benefit the SEO of the page, since a keyword will be associated to the image.

6. Image dimensions : Defining image dimensions improves SEO on pages with AMP and PWA. Furthermore, it will also allow browsers to resize images faster, even before the CSS loads.

7. Images for mobiles: It is important that the images are «mobile-friendly». To do this, you must create responsive images that scale in size with the page and fit the size of the device.
