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.

Need a layman's definition/analogy of the difference between schema and structured data
I'm currently writing a blog post about schema. However I want to set the record straight that schema is not exactly the same as structured data, although both are often used interchangeably. I understand this schema.org is a vocabulary of global identifiers for properties and things. Structured data is what Google officially stated as "a standard way to annotate your content so machines can understand it..." Does anybody know of a good analogy to compare the two? Thanks!

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?

Index process multi language website for different countries
We are in charge of a website with 7 languages for 16 countries. There are only slight content differences by countries (google.de | google.co.uk). The website is set-up with the correct language & country annotation e.g. de/DE/ | de/CH/ | en/GB/ | en/IE. All unwanted annotations are blocked by robots.txt. The «hreflang alternate» are also set. The objective is, to make the website visible in local search engines. Therefore we have submitted a overview sitemap connected with a sitemap per country. The sitemap has been submitted now for quite a while, but Google has indexed only 10 % of the content. We are looking for suggestion to boost the index process.

Using both dofollow & nofollow links within the same blog site (but different post).
Hi all, I have been actively pursuing bloggers for my site in order to build page rank. My website sells women undergarments that are more on the exotic end. I noticed a large amount of prospective bloggers demand product samples. As already confirm, bloggers that are given "free" samples should use a rel=no follow attribute in their links. Unfortunately this does not build my page rank or transfer links juice. My question is this: is it advisable for them to also blog additional posts and include dofollow links? The idea is for the blogger to use a nofollow when posting about the sample and a regular link for a secondary post at a later time. What are you thoughts concerning this matter?

Two Pages with the Same Name Different URL's
I was hoping someone could give me some insight into a perplexing issue that I am having with my website. I run an 20K product ecommerce website and I am finding it necessary to have two pages for my content: 1 for content category pages about wigets one for shop pages for wigets 1st page would be .com/shop/wiget/ 2nd page would be .com/content/wiget/ The 1st page would be a catalogue of all the products with filters for the customer to narrow down wigets. So ultimately the URL for the shop page could look like this when the customer filters down... .com/shop/wiget/color/shape/ The second page would be content all about the Wigets. This would be types of wigets colors of wigets, how wigets are used, links to articles about wigets etc. Here are my questions. 1. Is it bad to have two pages about wigets on the site, one for shopping and one for information. The issue here is when I combine my content wiget with my shop wiget page, no one buys anything. But I want to be able to provide Google the best experience for rankings. What is the best approach for Google and the customer? 2. Should I rel canonical all of my .com/shop/wiget/ + .com/wiget/color/ etc. pages to the .com/content/wiget/ page? Or, Should I be canonicalizing all of my .com/shop/wiget/color/etc pages to .com/shop/wiget/ page? 3. Ranking issues. As it is right now, I rank #1 for wiget color. This page on my site would be .com/shop/wiget/color/ . If I rel canonicalize all of my pages to .com/content/wiget/ I am going to loose my rankings because all of my shop/wiget/xxx/xxx/ pages will then point to .com/content/wiget/ page. I am just finding with these massive ecommerce sites that there is WAY to much potential for duplicate content, not enough room to allow Google the ability to rank long tail phrases all the while making it completely complicated to offer people pages that promote buying. As I said before, when I combine my content + shop pages together into one page, my sales hit the floor (like 0 - 15 dollars a day), when i just make a shop page my sales are like (1k+ a day). But I have noticed that ever since Penguin and Panda my rankings have fallen from #1 across the board to #15 and lower for a lot of my phrase with the exception of the one mentioned above. This is why I want to make an information page about wigets and a shop page for people to buy wigets. Please advise if you would. Thanks so much for any insight you can give me!

Splitting one Website into 2 Different New Websites with 301 redirects, help?
Here's the deal. My website stbands.com does fairly well. The only issue it is facing a long term branding crisis. It sells custom products and sporting goods. We decided that we want to make a sporting goods website for the retail stuff and then a custom site only focusing on the custom stuff. One website transformed and broken into 2 new ones, with two new brand names. The way we are thinking about doing this is doing a lot of 301 redirects, but what do we do with the homepage (stbands.com) and what is the best practice to make sure we don't lose traffic to the categories, etc.? Which new website do we 301 the homepage to? It's rough because for some keywords we rank 3 or 4 times on the first page. Scary times, but something must be done for the long term. Any advise is greatly appreciated. Thank you in advance. We are set for a busy next few months 🙂

Submitting URLs multiple times in different sitemaps
We have a very dynamic site, with a large number of pages. We use a sitemap index file, that points to several smaller sitemap files. The question is: Would there be any issue if we include the same URL in multiple sitemap files? Scenario: URL1 appears on sitemap1. 2 weeks later, the page at URL1 changes and we'd like to update it on a sitemap. Would it be acceptable to add URL1 as an entry in sitemap2? Would there be any issues with the same URL appearing multiple times? Thanks.
