They embed data such as :
And a lot more. EXIF data can really embed a lot of information. You can even find stories on SEO forums saying that EXIF data has been used by the police to solve cases.
When you realized that image SEO is almost only about helping Search Engines to understand your picture, you get why people have been discussing the potential impact of EXIF / IPTC on SEO.
Tips to excel in high society (or more likely in SEO Workshops) : EXIF standard was defined in Japan and there is absolutely nothing surprising about that since Sony, Fujifilm and Canon have their headquarters in Tokyo.
Everything started back in 2014, when Matt Cutt (working for Google at the time) announced in an ambiguous YouTube video that EXIF data from images could potentially be a ranking factor for Google Image. To quote Mr Cutt : “ It is something that Google is able to parse out and I think we do reserve the right to use it in ranking ! »
Since then it has been no consensus between SEO specialists on this topic.
Some of them were saying that EXIF Data had absolutely no impact on images SEO, meanwhile other pretended that they could rank better in Google using these metadata.

This being stated, ask yourself how you can improve your IPTC and EXIF data for SEO.
Even though EXIF / IPTC data are normally created during the JPEG compression, some tools allow you to edit the data.
The most well-known tools in the industry currently are Adobe Photoshop, Adobe Lightroom and The GIMP. I personally use The GIMP.
Here is the process for editing metadata on The GIMP :
On average, image metadata makes up for more than 15% of JPEG weight file on the web.
This is why they are often erased by image compression services. You therefore need to find a balance between EXIF / IPTC data that you can erase and the one that you want to keep.
