Keywords in the context of dental SEO
Are defined keywords still critical? Yes and no….
Three or four years ago I wrote a well-received article regarding the gradual demise of keyword importance for dental SEO and why some of the tactics being used to sell SEO services to dentists had largely become obsolete.
Let’s recap briefly on what keywords are and their history before moving on to how the use of keywords has changed in the last 3 or 4 years since I wrote that original article. We’ll also see how some search engine optimisation agencies still persist with old, defunct techniques and how that ultimately fails their clients.
Keywords – the history
In the infancy of Google and more generally SEO, keywords were perhaps the most important marker which told Google what a searcher was looking for. This was very much for discrete searches such as “dental implants” and consequently optimisers would cram websites full of the exact term in as many places as possible. This often made web text read very badly as websites were configured more for Google rather than users.
Google started to tackle keyword spamming and “thin” website content using punitive search algorithm penalties such as the infamous “Panda” update around 10 years ago and this did reduce the amount of optimisation spamming quite considerably. However, those “blunt” tools were complemented by arguably more subtle search engine updates several years later such as the “Rankbrain” and “Bert” updates in 2015 and 2019 respectively. It is these updates which have moved us to less of a reliance on simple discrete keywords and more focus on the context of what is actually written on a web page.
Rankbrain and Bert were key steps in the evolution of Google where the search engine became far more capable at recognising what a searcher was looking for, rather than just zeroing in on a specific keyword search. As an example, this means that Google understands that someone who is searching for “lost tooth replacement” is actually very likely to be interested in services providing dental implants. So we can see that we now need to be far more subtle when optimising a web page, rather than simply adding recurring instances of the same keywords and phrases.
