Check that the page is indexed via the meta-robots tag
Go to the page, right-click > view page source
Then do Ctrl + F and type “meta-robots”
If the tag exists, make sure it does not contain the directive "noindex" as below. If it does, Google has followed your reco, and deindexed the page.
If the tag does not exist (this is good, you have told Google to index it), or if it exists but has a “noindex” directive, let’s see if Google knows the page:

Ask yourself the following questions
Did my robots.txt file block the crawl of this page with a "Disallow" of this URL?
Did I change anything on this page last week and if so, what was it? Title, content, images, other?
Have I changed anything on my site that could have impacted this page? For example, I modified the menu or the structure of the site, and as a result the page would have received perhaps fewer internal links than before, making it less relevant in the eyes of Google.
