I'm working on a site and I feel like there might be something weird going on with the search queries. See the image below.
This site was impacted by poor links. In one day, about 10,000 links were removed by 404'ing the linked pages. Immediately after doing this, the search queries went stagnate. If you look back in time, the fluctuations in queries are much greater and more frequent.
Any ideas? Thanks.
