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://a-moz.groupbuyseo.org/learn/seo/google-hummingbird
https://a-moz.groupbuyseo.org/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.

Meta-description issue in SERPs for different countries
I'm working with a US client on the SEO for their large ecommerce website, I'm working on it from the UK. We've now optimised several of the pages including updating the meta-descriptions etc. The problem is when I search on the keyword iin the UK I see the new updated version of the meta-description in SERPs results. BUT when my client searches on the same keyword in the US they're see the old version of the meta-description. Does any one have any idea why this is happening and how we can resolve it? Thanks Tanya

Do I need to add the actual language for meta tags and description for different languages? cited for duplicate content for different language
Hi, I am fairly new to SEO and this community so pardon my questions. We recently launched on our drupal site mandarin language version for the entire site. And when i do the crawl site, i get duplicate content for the pages that are in mandarin. Is this a problem or can i ignore this? Should i make different page titles for the different languages? Also, for the metatag and descriptions, would it better in the native language for google to search for? thanks in advance.

Multiple pages optimised for the same keywords but pages are functionally different and visually different
Hi MOZ community! We're wondering what the implications would be on organic ranking by having 2 pages, which have quite different functionality were optimised for the same keywords. So, for example, one of the pages in question is
Intermediate & Advanced SEO | | TrueluxGroup
https://www.whichledlight.com/categories/led-spotlights
and the other page is
https://www.whichledlight.com/t/led-spotlights both of these pages are basically geared towards the keyword led spotlights the first link essentially shows the options for led spotlights, the different kind of fittings available, and the second link is a product search / results page for all products that are spotlights. We're wondering what the implications of this could be, as we are currently looking to improve the ranking for the site particularly for this keyword. Is this even safe to do? Especially since we're at the bottom of the hill of climbing the ranking ladder of this keyword. Give us a shout if you want any more detail on this to answer more easily 🙂0 -
:Pointing hreflang to a different domain
Hi all, Let's say I have two websites: www.mywebsite.com and www.mywebsite.de - they share a lot of content but the main categories and URLs are almost always different. Am I right in saying I can't just set the hreflang tag on every page of www.mywebsite.com to read: rel='alternate' hreflang='de' href='http://mywebsite.de' /> That just won't do anything, right? Am I also right in saying that the only way to use hreflang properly across two domains is to have a customer hreflang tag on every page that has identical content translated into German? So for this page: www.mywebsite.com/page.html my hreflang tag for the german users would be: <link < span="">rel='alternate' hreflang='de' href='http://mywebsite.de/page.html' /></link <> Thanks for your time.

Substantial difference between Number of Indexed Pages and Sitemap Pages
Hey there, I am doing a website audit at the moment. I've notices substantial differences in the number of pages indexed (search console), the number of pages in the sitemap and the number I am getting when I crawl the page with screamingfrog (see below). Would those discrepancies concern you? The website and its rankings seems fine otherwise. Total indexed: 2,360 (Search Consule)

Mobile website on a different URL address?
My client has an old eCommerce website that is ranking high in Google. The website is not responsive for mobile devices. The client wants to create a responsive design mobile version of the website and put it on a different URL address. There would be a link on the current page pointing to the external mobile website. Is this approach ok or not? The reason why the client does not want to change the design of the current website is because he does not have the budget to do so and there are a lot of pages that would need to be moved to the new design. Any advice would be appreciated.

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

Best practice for duplicate website content: same root domain name but different extension
Hi there I have a new client who has two websites: http://www.bayofislandsteambuilding.co.nz
Intermediate & Advanced SEO | | turnbullholdingsltd
http://www.bayofislandsteambuilding.org.nz They are the same in every regard apart from the domain extension (.co.nz & .org.nz) which is likely to be causing them issues with Google ranking given the huge amount of duplicate content. What is the best practice approach to fixing this? Normally, if I was starting from scratch, I would set one of the extensions as an alias which redirects to the main domain. Thanks in advance.
