Google deindexed two-thirds of our site in one day: A troubleshooting story

The team behind Toolevia, a project offering 84 browser-based file tools, faced a sudden traffic collapse. Following a successful August launch, where the site was rapidly indexed and gained impressions, a crash occurred on August 21st: Google impressions plummeted from thousands to just a few per day. The developers spent two weeks investigating, suspecting technical errors or SEO issues. The article details their troubleshooting process, the search for the 'culprit' behind the deindexing, and the unexpected conclusions they reached. This case highlights the complexities of promoting new web projects and the unpredictability of search engine algorithms faced by developers of browser-based services. The author shares their experience in diagnosing these issues and invites the community to discuss similar situations, noting that even without a server-side backend (as all calculations occur on the client side), a site can still fall victim to search engine filters.
