Google, on October 26, 2015, officially announced that RankBrain is the third most important SEO factor in Google ranking. The other two most important SEO factors are Links and Content.

So, in addition to focusing on quality content and link building, Brain Rank must also be a special concern for bloggers, so that their blogs are ranked on Google or at least stay in their best position.
Understanding Brain Rank and Its Application in SEO Blog
Understanding Brain Rank
From various reviews, including the Search Engine Land and Backlinko pages, Brain Rank is a learning engine based algorithm. Brain Rank - by Harfiyah means "Brain Ranking" - helps Google process search results and provide search results that are more relevant to users.

This means, now we are not enough to bombard the blog pages with relevant keywords. Rankbrain checks whether everything on the website is exactly what the user wants.

Application of Brain Rank in Blog SEO
Here are recommendations from SEO experts to adapt to Google Brain Rank.

1. Long and relevant blog posts.
Winning long writing is not liked by the reader. They want concise and clear writing. Moreover, reading on the screen is tiring eyes.

However, Rank Brain forced bloggers and content writers to write long articles, so the reviews were complete, in-depth, detailed, comprehensive, because Brain Rank treated keywords as a concept known as Latent Semantic Indexing (LSI).

The longer your blog article is, the more likely it is for people to linger on your page (as long as you make it interesting and quite relevant). The length of time visitors use is known as Dwell Time.

Blog content must attract the attention of the audience. The main goal is not only to make articles satisfying visitors, but also to optimize crawling and indexing (Google Crawler).

Make sure your posts are interesting and useful for visitors. Google Rankbrain can see and "understand" that users really like it. That is why Google will rate your page higher.

Long, quality content also shows "content is king" (content is king) remains relevant, even more relevant associated with Brain Rank.

Quality articles will also bring backlinks, so Google is increasingly interested in placing blogs in the top rankings.

2. Fresh & Clear content
Make sure your blog content is fresh, fresh, updated, and clear or easy to read by readers. Google always takes sides with users. What satisfies the user, will satisfy Google too. What users don't like, will have an impact on the blog's reputation in Google's eyes.

RankBrain focuses on content. If you have good content, you can easily optimize your blog.

If your content isn't good, your clickthrough rate will decrease. The reader will not return to your website and that will cause a lower ranking in RankBrain.

Apparently, RankBrain makes it more difficult for websites to get better rankings.

3. Keywords
You don't need to focus too much on finding relevant keywords. If you write an article about "desserts", RankBrain will take "desserts" and related terms as keywords. So, words like "candy" and "sweet dish" will also be considered as keywords.

With RankBrain, your article might rank questions related to desserts and sweet dishes. So keyword density should not be your focus anymore.

You must focus more on overcoming user intentions through your content. This is because quality content is the most important for the reader. Quality content that focuses on the user's intent will result in a higher CTR.

Because RankBrain improves the quality of search results, it also collects information about user satisfaction.

The best way to optimize RankBrain is to optimize for "medium tail keywords" (medium tail keyword). Optimizing medium-tailed keywords provides automatic optimization for long tail keywords in RankBrain.

This also requires you to create better quality content. This makes it easier to optimize it for medium tail keywords.

Looks like Rank Brain makes a lot of blogs displaced on page one of Google. Visitors also declined. However, quality, deep, and useful content will always be a winner. Just focusing on content because Content will always be the King
