Page I have not touched in two years dropped 60 percent of traffic in nine days Traffic Drop

Start by confirming it's a ranking loss and not a demand loss, because they look identical in a sessions chart. Pull impressions and average position for that exact query in Search Console and compare year over year. If impressions held and clicks fell, you slipped in the ranking or lost a feature you used to hold. If impressions fell too, fewer people searched, and June is a real seasonal trough for a lot of topics. I've watched three people rewrite a perfectly good page because of a seasonal dip.

Screenshot the current result page and count what's above the first organic listing. Twice now I've had a 'ranking drop' that was actually four new blocks pushed above me, so position 3 became position 3 below the fold. Nothing you write fixes that, but it changes what you do next, which is usually go after the format that's winning the space rather than the blue link.

Check whether the page lost internal links. This happens more than people think. Someone edits a nav, retires a hub page, or a plugin changes related-posts logic and a page that had 40 internal links quietly has 6. Crawl the site now and compare to any old crawl you have. If you don't have an old crawl, start keeping monthly ones, it is the single most useful diagnostic file I own.

Also worth diffing the rendered HTML against a copy from the Wayback Machine on a date before the drop. 'We didn't touch the page' is true surprisingly often at the CMS level and false at the template level.

Check server logs for that URL over the same window. If crawl frequency collapsed at the same time, you may have a response time or 5xx issue on a specific edge node rather than anything to do with the content.
