Does data-bind hurt SEO?
-
sleepcountry.ca uses Oracle Commerce Cloud which uses Knockout data-binds syntax to attach events to DOM elements like this (A <a id="s0207useresourcesinwidgets01"></a>Knockout custom binding named ‘widgetLocaleText’ - I am not familiar this technology stack):
Same applies to H1 tag - you can't find H1 tag in Source.
In short, the text binding causes the associated DOM element to display the text value of your parameter. Data binding is applied to all DOM elements on pages of sleepcountry.ca even that this technique doesn't pass W3C markup validation: Error: Element
titlemust not be empty.MOZ reports that all H1 Tags are missing on ALL PAGES of the site. Same is reported by Semrush and other respected services. However, it seems like Google automatically adds tagging to all data-bind(ed) elements including Title! site:sleepcountry.ca
I'm no expert in Oracle Commerce Cloud or Knockout, but I'm confused.
QUESTION: Does this data-bind hurt organic search and if it does, why Google still sees all TITLES while Moz and other services report it as a major problem - titles are missing. ?Thank you so much in advance! (I'm not an SEO expert but this problem might be related to my project)

No problem! A good golden rule of JavaScript SEO is to always SSR where possible. Let me know if you have any other questions!

Chris, thank you so much for your response. It looks like since client-side rendering is used, it builds virtual DOM and attaches events to make the page interactive, However, with SSR approach, the user could start viewing the page while all of that is happening. Since I'm reviewing the website performance, SSR should be generally faster than client side rendering to the user. Even if Google still indexes majority of pages it doesn't mean that those pages will be ranked high because of the delayed page load. Thank you for much for sending me to the right direction. I didn't think of this option before you responded.

Basically those tools aren't reading the DOM but Google can which is why it can see your site's title tags, H1s etc. Your site is using client-side rendering which Google can crawl through. Notice how if you go to a given page and click "View Source", none of the page's content appears.
While it appears Google is reading the content in the pages I looked at, I would definitely look into this more to see if Google is able to crawl/index the content on all of your site's pages. Client side rendering is less reliable than SSR so there might be instances where Google isn't reading sections of your content.

Does Moz's keyword tool pull data from your IP address?
Does anyone know how Moz's keyword tool pulls their keyword ranks? Do they take it based off of the IP (history and cookies) that is being used? I am trying to find a way to collect keyword data that is neutral and not based off of my previous searches, etc. TIA

Unusual "internal links" causing SEO issues?
Hi all, I'm working on an ecommerce site which has been around for almost 20 years. Over the years it has started to suffer in Google's search results and the decision was recently made to completely overhaul the site. We're now very happy with the website's design, and care was taken to maintain page rank via 301s, etc. However, the site has just fallen off the bottom of Google's first search result page (for the first time in years) for our main keyword. I signed up here in the hope of using Moz's SEO tools to help us return to our former glory, but I'm seeing some confusing results: I've run a crawl test on our site, as well as on our two biggest competitors. One thing that really stood out was that we have over 1000 "internal links" to our homepage, whereas our competitors both have around 20-30 (both of which appear at the top of the first SR page). Since the rest of the "on-page SEO" looks OK, I suspect that this could be causing our problems, but I don't understand where this "internal links" number is coming from. Links to our competitor's homepage appear in the navigation bar on every single one of their product pages (which they have about 500 of), yet your report only claims that they have 30 links. The only link to the homepage appears in the site's main navigation bar (which obviously appears on every product page - exactly as it does on our competitors' sites). Additionally, almost every other page on our site apparently has 0 "internal links" and 0 page authority. Is this a problem with Moz's crawl test tool, or is our site actually at fault? The above has been asked directly to Moz staff, but I haven't had a reply. I'd hugely appreciate any words of wisdom from the community. Many thanks in advance. Nick

How do I go about fixing my High Priority issues that SEO moz says I have on a PHP site?
I am been trying to deal with this problem for some time now. I have talked to several IT people and SEO moz. None seem to know how to fix these issues on the type of site our company is. Our biggest issue with is Duplicate Page Content. We also have some title issues. Our site is built with PHP coding and variable, meaning the site is not a typical static website. We have a handful of pages that are dynamic depending on what the users chooses to see and do. So, my problem is I can't just go to a specific page and put the canonical or the redirect. It isn't multiple pages for our category pages, for example, it is just one that builds the page depending on the search. Please help!

Monthly Data Option not appearing in Moz AGAIN
Hello Again, It's a real shame that I seem to come to this forum to only complain about your product again and again. I remember a time when I used to really respect this company, but your tool is absolutely abysmal. Anyway, my latest issue (to add to the pile) is that campaigns that have been in my account for almost 2 months STILL do have options for me to make monthly reports on. What's wrong now? Edit: I just checked the date I added these profiles, it was around the end of last month, so one and a half months ago.

Does anyone have a good article or video on how to read the SEO MOZ crawl report column by column?
I am trying to find a good how-to on how to read and analyze each column of the SEO MOZ crawl report, specifically, the excel sheet it allows you to export. What I'm really trying to get to the bottom of is what the "Yes" indiciates under rel-cononical. If it says "yes," does this mean that the link in question has been canonoicalized?

SEO REPORT
Hi, I have already searched the forum for this but the previous responses were a while ago. I used to think that there was a way of creating a SEO report using the information from Moz? But I can't seem to find that option now? Is there a way to create a report?

Why isn't seo moz properly crawling my site?
In my campaign results, only 2 pages have been crawled, when there are many more. Also, when I do the on-page evaluation for my homepage and the main keyword, I get a grade of F, with a ton of errors that my page actually does not have. It's as if SEO moz is having trouble crawling through my site. Any ideas on this?
