A noticeable algorithm glitch affected Google search results two days ago, causing significant fluctuations that jumbled the search engine's results. The glitch was under speculation for hours while SEO community attempted to figure out the strange and perplexing algorithm update.
The day after Google suffered the glitch, Webmaster Trends Analyst John Mueller confirmed the issue and said that it had been fixed in the meantime.
Users from all over the world experienced the glitch in the form of low quality results on the first page of Google's search results and multiple page one listings for single sites. It looked like a severe state of disorder and the Australian SEO community pointed out that the Google search results started to appear more like Bing's search results.
Google hasn't commented on the glitch. The SEO community awaits the response from Danny Sullivan, the source responsible for the announcement of Google updates. Some members of the SEO community are suggesting that the glitch may have been a result of Google testing a significant core update that it might soon release.
Nobody knows the definite cause behind Google's algorithm glitch and it can only be confirmed from the company's own source that hasn't said anything about it as of yet.
