Do subdomains negatively impact SEO
-
If we want to eliminate one of our domains and consolidate it with our main domain by the subdomain approach, would that negatively impact our SEO? Example: change www.xyz.org to www.xyz.abcd.org,
Thanks, in advance, for your feedback.

I think you may have some traffic loss in the short-term, but over the long term, you ought to be able to get the site traffic back up, especially if you point the old domain to the new subdomain, along with related 301 redirects for individual pages, if you keep the same or a similar site structure.
I happened to have read this earlier today.
"Keep in mind though that subdomains may not fully benefit from the link equity, positive metrics or rankings from the main domain they are associated with and vice versa, if Google thinks of them as being under separate ownership. For example, a blog on blogspot.com does not benefit from the authority of blogspot.com.
That said, if you already have content on a subdomain, it’s worth noting that the effort and consequences of moving that content to a root domain is typically not worth it, unless you spot an issue that compels you to do so.
(If you do decide to move the content from a subdomain to your main domain, a short-term loss in traffic is typical.)"
Via Moz's Top 10 newsletter: https://www.stonetemple.com/subfolders-subdomains-microsites-and-seo/
So, I think you need to fully evaluate the value of moving to a subdomain over staying on a 2nd level domain.

My own experience is that subdomains don't hurt. I have several subdomains on my own site, and pages on that site are top ten in Google. Despite everything that I've read saying that a subdomain doesn't benefit from being attached to a strong domain, my experience has told me otherwise. Perhaps it's because most SEO advice is geared to Big Biz SEO vs. Local SEO. That's why I love MOZ so much, they don't ignore the little guys.

I would certainly avoid it unless you have a specific purpose.
If Google can see the site it will certainly index it.
Domain structure is only a small element of the ranking signals.
If you have links pointing to the domain you will need to set up redirects to maintain your link structure, you may lose a small amount of authority losing a 301 but not much.
Hope that helps
All the best

Display ads and SEO
I have a section(no. of webpages with content) on my site with display ads. The site is mainly for UK visitors. I want to show ads to UK visitors but not US visitors. Rest of the content will be the same for UK and US. There will just be 1 page with same UrL for US and UK. Hence, no href lang tags are being used.

Is there any correlation between display ads and SEO? Would not showing ads in US cause any issues for bots or do bots consider display ads and SEO as two completey different aspects. Asking as Google bot crawls from the US.1 -
Help Center/Knowledgebase effects on SEO: Is it worth my time fixing technical issues on no-indexed subdomain pages?
We're a SaaS company and have a pretty extensive help center resource on a subdomain (help.domain.com). This has been set up and managed over a few years by someone with no knowledge of SEO, meaning technical things like 404 links, bad redirects and http/https mixes have not been paid attention to. Every page on this subdomain is set to NOT be indexed in search engines, but we do sometimes link to help pages from indexable posts on the main domain. After spending time fixing problems on our main website, our site audits now flag almost solely errors and issues on these non-indexable help center pages every week. So my question is: is it worth my time fixing technical issues on a help center subdomain that has all its pages non-indexable in search engines? I don't manage this section of the site, and so getting fixes done is a laborious process that requires going through someone else - something I'd rather only do if necessary.

SEO Problems with Loading to a Subfolder?
A client has a single page app website that shows https://example.com/example when you visit https://example.com . I don't think this is a redirect; I think it's a URL rewrite. My questions: Is this setup common with single page apps? What are the SEO benefits or drawbacks of having a domain's homepage load, rewrite, or redirect to a subfolder?

SEO impact of the anatomy of URL subdirectory structure?
I've been pushing hard to get our Americas site (DA 34) integrated with our higher domain authority (DA 51) international website. Currently our international website is setup in the following format... website.com/us-en/ website.com/fr-fr/ etc... The problem that I am facing is that I need my development framework installed in it's own directory. It cannot be at the root of the website (website.com) since that is where the other websites (us-en, fr-fr, etc.) are being generated from. Though we will have control of /us-en/ after the integration I cannot use that as the website main directory since the americas website is going to be designed for scalability (eventually adopting all regions and languages) so it cannot be region specific. What we're looking at is website.com/[base]/us-en. I'm afraid that if base has any length to it in terms of characters it is going to dilute the SEO value of whatever comes after it in the URL (website.com/[base]/us-en/store/product-name.html). Any recommendations?

If the order of products on a page changes each time the page is loaded, does this have a negative effect on the SEO of those pages?
Hello, a client of mine has a number of category pages that each have a list of products. Each time the page is reloaded the order of those products changes. Does this have a negative effect on the pages' rankings? Thank you

Directing traffic to subdomain
Hi everyone, For this question, please note that we will be directing traffic using a load balancer (an Amazon ELB, to be specific) rather than using a 301 redirect. The question: Will the SEO ranking of links to pages be negatively impacted by directing traffic to servers with a different hostname (or subdomain) within mycompany.com? For example, we would like to have www.mycompany.com load balanced between host1.mycompany.com and host2.mycompany.com. Many thanks for your input! Jay

Advertising and negative impact on SEO
On one of my sites, I've been trying to get the word out by contacting blogs and asking them to share my site with their readers. This has resulted in some free publicity for my site, as well as quite a few paid reviews/sponsored posts. Note, however, that I've never paid for links, just reviews of my site... When I started this about 2 months ago, my site was a PR3 and getting fairly lowsy organic search traffic (i.e. 30-40 visits a day from Google). Then a few days ago, my PR dropped to 1. I didn't worry too much though, because my organic traffic was still around 30-40 visits a day. Now today, I checked and I only had 1 visitor the entire day from Google. Obviously I've been penalized. My most important question is, what can I do? Do I have an recourse, or do I need to just shut the domain down and move elsewhere? Second, wtf is Google penalizing this? I understand the argument against paid links, but should I not be allowed to advertise my site? Apparently I can buy links all day long through Google and they'll happily take my money, but the minute I pay some poor blogger to write an article about my site to their audience, I get penalized? Please help, I can't believe I just destroyed one of my sites like this!
