What is Google Update?
Have you ever read this "Don't write for a machine, write for humans." Over the years of doing Search Engine Optimization that, too, with the White Hat Technique, I believe that Google follows this straightforward logic to show search engine results pages (SERPs). Earlier, we never used to get so many updates from Google, but now there are more than a thousand updates every year from Google.
Frankly speaking, the majority of these get ignored; only a few get the attention of SEO Analysts. Google keeps on updating these algorithms to generate relatable search results. In a constant effort to make the Search Engine usable to the masses, these updates are necessary; otherwise, it will end up like Yahoo.
Some major Google Algorithm Updates are:-
How can it affect SEO?
People who prefer to do Black Hat SEO can understand the impact of such updates very well. Correct me if I am wrong! In general, if you don't follow ethical keyword ranking, your keywords ranking will downgrade, thereby lowering the website traffic. One of my client www.maxiadventures.com has a subscription to White Hat SEO services from my company, and we got NIL deflections in keywords ranking. Doing ethical SEO will get long term functional results, so don't rush to get results within a week.
About Bert Update.
First of all, let's understand the BERT Update.
If you know Google Algorithm Updates, then you must have heard about the RankBrain Algorithm Update. It came five years ago, but it's the most potent Algorithm Update of Google. To give you an idea about this Algorithm change, this Update changed the way Google reads the queries and shows the related search query pages.
BERT will affect 10% of the search queries, i.e., 10% of 3.5 Billion search queries per day. BERT is basically for long-tail keywords. If a layman is searching for anything on Google, he must get the related product/service from different web pages.
I am moving to the ranking of your keywords. Will you be affected by these changes?
Yes, or not depends on the content that you have written for your website. In any case, your ranking is going down; you can't do anything except writing good content for your business. Unless your written content is answering the queries, everything will be fine. Don't worry; Sunder Pichai won't betray you.
