I know, I know, you can’t really catch a cow when you go fishing, can you? Well, you can when you realise that a cow is actually another name for a large, striped, saltwater game fish.
And BERT (Bidirectional Encoder Representations from Transformers) is a major update to the Google search algorithm that has nothing to do with Transformers films or toys
What does BERT do?
Google has been consistently trying to understand the context of the words used in Google searches. In the early days of Google they just searched on the words used in the query without attempting to understand the context. So, if you wanted to go on holiday to Majorca and wanted a hotel with a swimming pool you might search using “Hotel Majorca Swimming Pool” for example.
However, your results might include the Hotel Majorca on Swimming Pool Road in Lowestoft or a hotel on Majorca Avenue in Andover or other results based on any combination of the words without understanding the real nature of your search.
Next up came semantic search which was Google’s first attempt to understand context of searches but my experience was that it wasn’t really that much of an improvement on what went before.
And this is where BERT comes in, BERT is a “deep learning algorithm that is related to natural language processing” and it helps a machine to actually understand what the words in a sentence mean, and can take in to account all of the nuances that are included in human speech.
Roger Monti of the Search Engine Journal was looking for a search phrase that he could use to demonstrate how context was interpreted and settled on “how to catch a cow fishing”.
Before BERT, Google returned a lot of results based on livestock and cows in particular. However, following the BERT roll out Google used “fishing” to understand the context and the same search, conducted, by Roger, at the end of October was full of striped bass and fishing related results.
Do I have to do anything on my website?
Not really. You just need to make sure that you continue to deliver quality, focused content and continue to use synonyms where relevant and appropriate.
BERT is currently rolling out globally and so may not have reached a Google Server near you, yet,
