Perhaps—however let’s take a deeper have a look at what makes search engine rankings so unstable.
The Fundamentals: How Search Rankings Are Calculated

When a person inputs a question, Google makes an attempt to carry that person the absolute best leads to its search engine outcomes pages (SERPs). To do this, it wants to supply outcomes which might be each contextually related and reliable.
Contextually related content material is chosen primarily based on the type of content it is and its relationship to the preliminary question. For instance, should you seek for one thing like “tech startups,” you’ll wish to discover precise tech startups or articles about them, somewhat than content material about scorching canine stands or water balloons. This appears apparent, however coding a machine to find out relevance is extra advanced than it first seems.

Site owners and content material creators have been fast to attempt to sport the system, manipulating their content material and spamming hyperlinks as black hat techniques to enhance their rankings. To fight this, Google refined its parameters for what it thought of to be “high quality” content material. Within the early 2010s, a collection of main updates named after animals (Panda, Penguin, and Hummingbird, to be actual) helped set up higher requirements for content material analysis, hyperlink analysis, and question interpretation, respectively.
Since then, Google has launched a excessive variety of smaller, but impactful updates. In reality, there have been hundreds of micro-updates in 2018 alone.

Did a hyperlink from a brand new, high-authority supply lastly push your competitor previous you when it comes to authority? Did you come out with a brand new weblog submit that’s extra attention-grabbing or extra related than the content material that got here earlier than it?
When mixed with the sheer frequency of updates to Google’s search algorithm, it’s plain to see why there are such a lot of disruptions in search rankings.
