I am using Google Satellite (via QuickMapServices) in QGIS to count settlements in a certain area, and I'm looking to compare this settlement data to satellite imagery from a few years back.

Is there a way to know what year the current Google Satellite imagery was taken? Does QuickMapServices update this continuously?

QuickMapServices is only a catalog, not a geodata hosting. Like a search services (google, bing, etc.) this service provides only links, not a data. So, QMS knows nothing about google satellite capture date and any other metadata. QMS only knows details which user, who create service, added and, additionally, service status.

    @Aaron do you mean that I should add that I'm working in NextGIS which supported free and opensource QuickMapServices service? The link you provide not clearly clarify this. Or I cannot answer any questions directly or indirectly connected with our services and software? – Dmitry Baryshnikov Sep 14 at 13:06

    affiliation information is clarification and also nice to see on GIS.SE having the actual developers onboard to answer specific questions. – Mapperz Sep 14 at 14:27

If you open the layer properties for any layer from QuickMapServices, you will see a link to an attribution guide for the particular data provider.

enter image description here

By following that link you will get to the website for that data provider, where you should also be able to find information about their data management practices.

If you want to view Google satellite imagery from a specific time period, Google Earth Pro for Desktop lets you select the year and season. You could conceivably use this tool to figure out when the satellite imagery in your QGIS project is from.

In practice, it may not be possible to know when satellite imagery on a WMS layer is from. If this is important to your project, you may want to directly download source data, such as Landsat data (which is available for free from the USGS).
