Difference hummingbird and rankbrain
-
From my understanding hummingbird is the fact that google is able to parse sentences and link entites to understand the meaning of content in a better way than with just keywords and rankbrain is about user intent, google understands that they are various ways to mean the same thing.
Is my understanding correct ?
Thank you,
-
I totally agree, thank you for your detailed explanation.
-
You can't really "optimize" for Hummingbird, but understanding RankBrain can certainly help you do keyword research and write relevant content better.
-
I know it's not very clear, but I think the important thing to remember about Hummingbird is that it was a complete rebuild of the core algorithm. I think natural language queries drove part of that rebuild, but Hummingbird covers a lot of ground and will be powering algo updates for months or years. As Danny said, it's like they put a whole new engine in the car. RankBrain is much more specific.

Thank you for the information Dr Pete. It is a little more clear. If I understand correctly rank brain is really about user intent in rewriting the query and Hummbird seems to be about voice searches and parsing but it is a little blurry in my mind as you would say other that people at google nobody really understands it fully.
Thank you,

I'm afraid it's probably more complicated than that, and I'm not sure anyone outside of Google (and most of the people inside of Google) has a handle on all of the details.
Hummingbird was very broad. It wasn't just an update, but an entire rebuild of Google's core "engine." When Google launched it, they gave examples that make us think a lot of the updates were necessitated by natural-language queries (voice certainly created some of that pressure). So, it definitely changed how Google processed very-long-tail queries, but I think it also created a framework for much more (and may have even been a foundation for RankBrain). Danny's very early FAQ is still a good resource:
https://searchengineland.com/google-hummingbird-172816
RankBrain causes confusion because it gets conflated with ML in search in general, but I think RankBrain has a very specific meaning to Google. I've written about it quite a bit and have had a handful of private conversations with Google employees, and still don't feel like I have all the facts. Here's what I'm comfortable saying... It is an ML-based approach to understanding query relevance, very likely related to models like Word2Vec. Best I know, it acts as a sort of re-ranking layer. So, Google returns results and then RB re-sorts them based on its understanding of relevance. So, truth be told, it's probably not as impactful as some folks think (ML in search could be much broader). It's most active for long-tail, natural-language queries, so there's some connection to Hummingbird, conceptually.

Thank yo. I read it and rank brain is clear hummingbird a little less but I think it is about the knowledge graph and parsing from what I understand.

Hi There!
We have two nice resources here on Moz that should help you feel totally clear on Hummingbird vs. Rankbrain:
https://moz.com/learn/seo/google-hummingbird
https://moz.com/learn/seo/google-rankbrain
Hope these help, but please let me know if you have any questions remaining after reading through those! I'm pretty sure I wrote both of them, so if anything isn't clear, just ask

Hello,
"RankBrain is an algorithm learning artificial intelligence system" - Wiki
Hummingbird is an update of Google's ranking algorithm.
They aren't something comparable because one is a system and one is a codename of an update to a system.
Hope this answered your question.

How To Optimize For Same Word, Different Spelling
Hi all. Just wondering what peoples stance is on using multiple variations of keywords on a webpage - those keywords that have the same meaning and search intent, but are just spelt differently. i.e. 'woodscrews' and 'wood screws' (the latter has a significantly higher search volume) You could approach the webpage in 4 different ways; 1. Use ONLY 'wood screws' on-page, and in the page <title><br />2. Use ONLY 'woodscrews' on-page, and in the page <title><br />3. Use BOTH 'wood screws' and 'woodscrews' on-page, and BOTH in the page <title><br />4. Use BOTH 'wood screws' and 'woodscrews' on-page, but ONLY one variation in the page <title></p> <p>We've run some tests in the past but there were never any clear takeaways, a mixed bag of results really.</p> <p>Also, If they are considered the same keyword by Google why are the ranking positions always different for each variation?</p> <p>I'm not sure there' a specific answer to this, just interested to hear peoples thoughts really.</p> <p>Many thanks in advance!</p> <p>Lee.</p></title>

Benefits/drawbacks to different Schema markup languages (ie. JSON-LD, Microdata, RDFa)
Just a question (or questions) I have wondered about. What's the difference, besides the actual encoding, between the three? Why have three? Why not just the one? Seems to me that Microdata is the easiest, but maybe I am wrong. Is there a reason to use one versus another? I have not found anything explaining this on schema.org - I suppose this is just a discussion versus getting one right or wrong answer. I am just curious of the opinions of people in the SEO MOZ community. Unless of course there is one answer. I'll take that too.

SEO impact difference between a URL Rewrite and 301 redirect
Hi guys and girls! Just putting a new site live, we changed the URL from one thing to another and I created a 301 file redirecting the urls like for like. The developer installing it has created a different file with columns like: RewriteRule ^page/ http://www.site/page [R=301,L] RewriteRule ^/page/ http://www.site/page [R=301,L] What's the difference? The page redirects but is there a difference between the 301 redirect and this URL rewrite in terms of SEO and link value?

Different Header on Home Page vs Sub pages
Hello, I am an SEO/PPC manager for a company that does a medical detox. You can see the site in question here: http://opiates.com. My question is, I've never heard of it specifically being a problem to have a different header on the home page of the site than on the subpages, but I rarely see it either. Most sites, if i'm not mistaken, use a consistent header across most of the site. However, a person i'm working for now said that she has had other SEO's look at the site (above) and they always say that it is a big SEO problem to have a different header on the homepage than on the subpages. Any thoughts on this subject? I've never heard of this before. Thanks, Jesse

Why would our server return a 301 status code when Googlebot visits from one IP, but a 200 from a different IP?
I have begun a daily process of analyzing a site's Web server log files and have noticed something that seems odd. There are several IP addresses from which Googlebot crawls that our server returns a 301 status code for every request, consistently, day after day. In nearly all cases, these are not URLs that should 301. When Googlebot visits from other IP addresses, the exact same pages are returned with a 200 status code. Is this normal? If so, why? If not, why not? I am concerned that our server returning an inaccurate status code is interfering with the site being effectively crawled as quickly and as often as it might be if this weren't happening. Thanks guys!

Duplicate content on sites from different countries
Hi, we have a client who currently has a lot of duplicate content with their UK and US website. Both websites are geographically targeted (via google webmaster tools) to their specific location and have the appropriate local domain extension. Is having duplicate content a major issue, since they are in two different countries and geographic regions of the world? Any statement from Google about this? Regards, Bill
