JavaScript page loader - SEO impact
-
Hello all,
I am working on a site that has a bizarre page load system. All pages get loaded trough the same Javascript snippet, for example:Changing the values in the form changes the page that is loaded.
The most incredible thing is that, against my expectations, pages do get indexed by Google.
My question is: "Does loading pages dynamically using JavaScript affect the overall SEO performance?"Why are pages getting indexed?
Thank you for shedding light on this.
Cheers

Hi Luca! So sorry for the wait. Yes, Google is able to load, crawl, and index pages written in Javascript. There are mixed reports as to how well, exactly, but your research is correct.

I have done my homework researching.
As a matter of fact since 2010 Google can crawl and execute JavaScript links, therefore the pages will be indexed and ranked exactly as static HTML pages.It would be nice to have confirmation on this

What's the best way to test Angular JS heavy page for SEO?
Hi Moz community, Our tech team has recently decided to try switching our product pages to be JavaScript dependent, this includes links, product descriptions and things like breadcrumbs in JS. Given my concerns, they will create a proof of concept with a few product pages in a QA environment so I can test the SEO implications of these changes. They are planning to use Angular 5 client side rendering without any prerendering. I suggested universal but they said the lift was too great, so we're testing to see if this works. I've read a lot of the articles in this guide to all things SEO and JS and am fairly confident in understanding when a site uses JS and how to troubleshoot to make sure everything is getting crawled and indexed. https://sitebulb.com/resources/guides/javascript-seo-resources/ However, I am not sure I'll be able to test the QA pages since they aren't indexable and lives behind a login. I will be able to crawl the page using Screaming Frog but that's generally regarded as what a crawler should be able to crawl and not really what Googlebot will actually be able to crawl and index. Any thoughts on this, is this concern valid? Thanks!

Does a no-indexed parent page impact its child pages?
If I have a page* in WordPress that is set as private and is no-indexed with Yoast, will that negatively affect the visibility of other pages that are set as children of that first page? *The context is that I want to organize some of the pages on a business's WordPress site into silos/directories. For example, if the business was a home remodeling company, it'd be convenient to keep all the pages about bathrooms, kitchens, additions, basements, etc. bundled together under a "services" parent page (/services/kitchens/, /services/bathrooms/, etc.). The thing is that the child pages will all be directly accessible from the menus, so there doesn't need to be anything on the parent /services/ page itself. Another such parent page/directory/category might be used to keep different photo gallery pages together (/galleries/kitchen-photos/, /galleries/bathroom-photos/, etc.). So again, would it be safe for pages like /services/kitchens/ and /galleries/addition-photos/ if the /services/ and /galleries/ pages (but not /galleries/* or anything like that) are no-indexed? Thanks!

Loading images below the fold? Impact on SEO
I got this from my developers. Does anyone know if this will be a SEO issue? We hope to lazy-load images below the fold where possible, to increase render speed - are you aware of any potential issues with this approach from an SEO point of view?

How Does Google's "index" find the location of pages in the "page directory" to return?
This is my understanding of how Google's search works, and I am unsure about one thing in specific: Google continuously crawls websites and stores each page it finds (let's call it "page directory") Google's "page directory" is a cache so it isn't the "live" version of the page Google has separate storage called "the index" which contains all the keywords searched. These keywords in "the index" point to the pages in the "page directory" that contain the same keywords. When someone searches a keyword, that keyword is accessed in the "index" and returns all relevant pages in the "page directory" These returned pages are given ranks based on the algorithm The one part I'm unsure of is how Google's "index" knows the location of relevant pages in the "page directory". The keyword entries in the "index" point to the "page directory" somehow. I'm thinking each page has a url in the "page directory", and the entries in the "index" contain these urls. Since Google's "page directory" is a cache, would the urls be the same as the live website (and would the keywords in the "index" point to these urls)? For example if webpage is found at wwww.website.com/page1, would the "page directory" store this page under that url in Google's cache? The reason I want to discuss this is to know the effects of changing a pages url by understanding how the search process works better.

Splitting Page Authority with two URLs for the same page.
Hello guys, My website is currently holding two different URLs for the same page and I am under the impression such set up is dividing my Page Authority and Link Juice. We currently have the following page with both URLs below: www.wbresearch.com/soldiertechnologyusa/home.aspx
Technical SEO | | JoaoPdaCosta-WBR
www.wbresearch.com/soldiertechnologyusa/ Analysing the page authority and backlinks I identified that we are splitting the amount of backlinks (links from sites, social media and therefore authority). "/home.aspx"
PA: 67
Linking Root Domains: 52
Total Links: 272 "/"
PA: 64
Linking Root Domains: 29
Total Links: 128 I am under the impression that if the URLs were the same we would maximise our backlinks and therefore page authority. My Question: How can I fix this? Should I have a 301 redirect from the page "/" to the "/home.aspx" therefore passing the authority and link juice of “/” directly to “/homes.aspx”? Trying to gather thoughts and ideas on this, suggestions are much appreciated? Thanks!0 -
Can you 301 redirect a page to an already existing/old page ?
If you delete a page (say a sub department/category page on an ecommerce store) should you 301 redirect its url to the nearest equivalent page still on the site or just delete and forget about it ? Generally should you try and 301 redirect any old pages your deleting if you can find suitable page with similar content to redirect to. Wont G consider it weird if you say a page has moved permenantly to such and such an address if that page/address existed before ? I presume its fine since say in the scenario of consolidating departments on your store you want to redirect the department page your going to delete to the existing pages/department you are consolidating old departments products into ?

What's the SEO impact of url suffixes?
Is there an advantage/disadvantage to adding an .html suffix to urls in a CMS like WordPress. Plugins exist to do it, but it seems better for the user to leave it off. What do search engines prefer?
