You also changed the homepage title tag from "Alamogordo NM Real Estate Listings, Homes, Properties, and Lots" to "Dei Gratia Real Estate - Alamogordo NM Homes For Sale." You may want to try a few title variations such as "Alamogordo NM Real Estate | Dei Gratia" etc.
I was checking your changes in webdesign, it looks like content & features for users (UX) changed completely. The new design looks good, but it lacks page speed in mobile version(just 14). Even the zip code in address is changed.
So addressing the page speed & little content optimization can bring back the ranking.
New advertising option:
A review of your product or service posted by a Sterling Sky employee. This will also be shared on the Sterling Sky & LSF Twitter accounts, our Facebook group, LinkedIn, and both newsletters.
