Welcome to the Q&A Forum

If the domain is decades old it can have high DA. I guess there are many links to those old domains as well. So, I do recommend keeping them unless you did a study and found that they don't attract any traffic. However, that's very unlikely.

Too long titles are not recommended. The optimal length is around 50-60 characters: https://moz.com/learn/seo/title-tag

It's OK to update the title and metas over time. That's one of the common steps to improve SEO.

I'm not sure I understand the question. Are you saying that your have around 50 pages with the same contents? Duplicate contents are not good for SEO: https://moz.com/learn/seo/duplicate-content

This blog article can clarify your doubts: https://moz.com/blog/nofollow-sponsored-ugc

For example, if Google suspects that those 20K links are  sponsored but they are tagged as UGC, then there can be a penalty. If those links are legitimate and the website DA is high, then those links can actually improve your reputation regardless of the nofollow attribute.

Hello,

Same problem here. I've emailed help@moz.com requesting assistance.

SEO for videos is a little bit more complex than SEO for web pages because it's necessary to generate the thumbnail for Google, add some code for compatibility with Facebook and other social networks, make it responsive and so on. You can do it yourself or use a plugin to automate all the necessary tasks. I haven't used Yoast Video SEO though. So, I can't tell you how good it is.

Both options have pros and cons. By embedding the articles into the relevant commercial sections you can burst the visibility of those sections (SEO). However, at the same time it will be harder to get backlinks from independent sources like blogs and news because they don't typically link to commercial contents.

So, currently you are using div to wrap the links to the product pages and you want to replace div with h2, right?

Google does like H tags. It will pay more attention to an h2 than a simple div. That's good for SEO.

The problem is that in your case the product entries are almost empty. There is not much content under each product name. It's almost like using h2 instead of LI (list item). Google will not like that.

So, unless you are planning to write some descriptions under each product name I don't recommend using h2 in this case.

Disavowing the spammy domains is not supposed to reduce the spam score because Moz has no visibility of the GSC disavow list. If you disavow a spammy domain you can reduce its negative impact from the Google perspective, but your own spam score will remain unchanged.

First of all, Google doesn't use Moz spam score: https://support.google.com/webmasters/thread/2440327?hl=en

So, if your Moz spam score is high because of "spammy" backlinks it doesn't mean that Google considers your site as spammy. You can check the spam score for every linking domain in the Link Explorer. If there are too "spammy" domains take the necessary actions (disavow them in GSC as the last resort).

A search engine can discover the pages not only through the sitemap. External links can have different formats and the webmaster doesn't control them. That's why the canonicals are always recommended.

No, you shouldn't remove the canonicals. They are useful to avoid impacting the SEO due to duplicate contents (multiple URLs resolving to the same content).

There are some very spammy linking domains redirecting to your site, for example: www.jyztpk.cn (spam socre 98%, DA 1)

I wonder if this is because you acquired a new domain and not because of the core update... You might have inherited all those bad links when you claimed the new domain.

Apparently Google doesn't care: https://support.google.com/webmasters/thread/21223241?hl=en

From the webmaster point of view it seems like more work to configure each individual property and review every report separately.

There are high DA domains like google.com. So, there is nothing wrong with having backlinks from .com domains. It's always recommended to check the authority and spam score for every linking domain regardless of the domain extension. The point is that ".com" is not necessarily lower quality than ".co.uk".

I don't think this kind of services are really useful today because most people work in home office or coworking spaces, which are anonymous.

Anyway, as a customer I'd be very disappointed if I find out that I'm being tracked. That's why I'd never use this kind of services in my websites.

This is a common question in this forum.

Maybe you got some new backlinks with low DA or maybe you've lost some high DA backlinks. You can start looking into your linking profile in the Moz Pro report. More info in this old thread: https://moz.com/community/q/why-my-domain-authority-da-is-decreased-from-21-to-19

There can be many reasons. Maybe you got some new backlinks with low DA or maybe you've lost some high DA backlinks. You can start looking into your linking profile in the Moz Pro report.

If you are new to SEO there is a beginner's guide here: https://moz.com/beginners-guide-to-seo

If you have specific questions, please ask.

150 links is the recommended maximum. If you have more links the search engine crawler will probably ignore them. The detailed answer is here: https://moz.com/learn/seo/internal-link
