LDS.org. As a genealogist, this also means that they have not looked at FamilySearch.org either. Even if many of those I speak with do happen to have a password and login, they have forgotten it which also indicates they do not visit these two websites. Looking at Google Trends, here is the graph showing website usage of LDS.org since 2011. The graph sets the highest usage of the website at 100 and so the trend is usage that falls below the highest previous point.
If I compare LDS.org to FamilySearch.org, here is the graph.
Without the comparison, here is the trend for FamilySearch.org.
For FamilySearch.org, the highest point of usage was in February, 2013 which is counted as 100. Currently, the usage is running at 14, a significant drop in interest and usage. It seems to me that the trend showing here correlates with my own experience in talking to people about both the main LDS.org website and FamilySearch.org. The graph for LDS.org show the distinct upticks in April and October for added usage around the time of General Conference.
To show another view of the online usage, I looked at the trend for Mormon.org, also starting in 2011.
In this case, the high point was right at the beginning of the graph for 100 and the current number is 34 with a definite uptick recently. But when you compare LDS.org to Mormon.org, you get a different perspective.
If I add in FamilySearch.org, I get the following graph.
What I think is happening is rather simple. There is a distinct movement throughout the world to move from desktop, more traditional usage of computer devices, to mobile devices. People are far less likely to search for and use a traditional website than they were just a few years ago. In fact, in 2015, Google changed its search technology to favor mobile friendly websites over those not adapted to mobile usage. See Wikipedia: Google Search. Although both LDS.org and FamilySearch.org have a certain amount of adaptation to mobile usage, neither website is really promoted for mobile usage and from a genealogical standpoint, the FamilySearch Indexing program is still not available in an online application and the program has to be downloaded to a desktop computer to work.
It is also interesting that searching for either "LDS" or "FamilySearch" on the Apple App Store does not result in finding any of the Church sponsored apps and the App Gallery on FamilySearch.org is hidden at the bottom of the webpages and virtually unused and unknown according to my experience. Searches for a "family tree app" have recently spiked according to the following graph from Google Trends.
Searches for "familysearch app" spiked in 2014, and finding a FamilySearch app is as easy as doing a Google search for the term. It seems to me that to increase user interest and use in both FamilySearch.org and LDS.org, there should be a clearer pathway to mobile usage and mobile usage should be encouraged, enabled and promoted.
