Image metadata has been around for a long time. Standards for image metadata however have been trying to keep pace with consumers’ appetite for digital content. As a consequence, image metadata standards have been in flux for a while. It has been very difficult for software makers to adapt both to new standards and customer demands as the two are almost always out of sync.
How do you verify that your Picasa image metadata is correct?
First, you have to have all metadata (at least everything that Picasa generates) in your JPG images created with Picasa. So, create all metadata available in Picasa: keywords , geo location , and face recognition name tags. Then upload your image to the excellent online tool provided by Jeffrey Fiedl (link at the bottom) .
Then go through every section of the output: EXIF, XMP and IPTC. It is an awesome tool.
Does Picasa save image keywords correctly?
According to current standards and best practices image keywords should be saved both to IPTC and XMP portions of a jpeg image header.
Picasa does indeed save keywords in the right place.
Picasa is saving keywords in the right places: both in IPTC and XMP portions of photo metadata.
Does Picasa save geodata correctly?
Geolocation information shuld be saved in the proper place in the EXIF image header.
Picasa does that correctly as well.
Geographical position is saved in the proper place in the EXIF portion of the JPEG image format.
I need to mention that there is some debate as to whether the Picasa geo coordinates are correct or not, but as far as saving the, Picasa does it right.
How about face recognition name tags
Face recognition name tags are the new kid on the block in terms of metadata standards. Being new, face recognition name tags do not have a place in the old IPTC standard but it does have a proper place in XMP.
Picasa saves face recognition name tags in the correct place again. How awesome is that!
Picasa saves face recognition name tags in the correct place in the XMP image header.
A simple conclusion about Picasa image metadata
Picasa is right on with the most important pieces of image metadata. Picasa saves them all in the right place. Granted, Picasa provides an interface only for a limited set of image metadata elements, but it saves them in the right place.

Essentials for organizing your digital photosOver the years I have come to rely on only a few products for managing and backing up my large media collection. These are my essential products and services I have been using for many years to keep things organized and safe. Even though these are affiliate links, I wholeheartedly recommend them.
I recommend using Adobe Lightroom Classic CC via the annual Adobe Creative Cloud subscription. Lightroom has excellent photo editing capabilities. Yes, Lightroom has a steeper learning curve as you have to learn to keep your catalogs in sync with your hard drive. However, Adobe Lightroom makes most sense especially when you do lots of image editing.
If you don't like the subscription, you can get also download the last standalone Adobe Lightroom 6 for Mac or Windows (while it is still available). However, the product is no longer maintained by Adobe.
Excellent Lightroom and Picasa alternative. If you're looking for a cheaper and simpler photo manager then ACDSee Photo Studio for Mac or ACDSee Pro for Windows is my preferred solution for organizing your media on your computer. It has a very fast browser, beautiful image editing capabilities and you don't work with catalogs at all.
In addition, make sure you have an inexpensive and reliable external hard drive for backing everything up. It is absolutely essential for backing up your media regularly.
If you're looking for a reliable unlimited cloud backup service, I recommend Backblaze Cloud Backup. I have used Backblaze for my online backup for more than 3 years now. All my files are safe and secure and I have never had any problems with them.
