Subdomain and root domain effects on SEO
-
I have a domain lets say it's mydomain.com, which has my web app already hosted on this domain. I wanted to create a sub-product from my company, the concept is a bit different than my original web app that is on mydomain.com and I am planning to host this on mynewapp.mydomain.com. I am having doubts that using a sub-domain will have an impact on my existing or new web app. Can anyone give me any pointers on this? As much as I wanted to use a directory mydomain.com/mynewapp, this is not possible because it will just confuse existing users of the new product/web app. I've heard that subdomains are essentially treated as a new site, is this true? If it is then I am fine with this, but is it also true that subdomains are harder to reach the top rank rather than a root domain?

Why not just buy a new domain if it is a totally separate product?
You are correct: a sub domain is essentially (for SEO purposes anyway) treated as its own entity.
As long as you build great content, find great link opportunities and treat it as you would any other domain you should have no problem getting it ranked.

No matter what you want to use it for, a sub domain is essentially its own domain and, it does not really affect your original domain. As to how a sub directory will will confuse your visitor but a subdomain won't, I do not see that as true. But, I think your real question is "is it harder for a subdomain to "rank" than a subdirectory? No, but let's be clear about what does rank in the SERPs: Pages.
So, you can have a sub domain with 5 pages that are able to rank just as easily as a domain that has five pages that rank. (Or one page, or 100). Given what you are wanting to sell, I would focus on UI/UX and ranking for the key terms for your apps. Quit worrying about the subdomain vs subdirectory. Choose one and rock on.
Best,
Robert

Sitewide nav linking from subdomain to main domain
I'm working on a site that was heavily impacted by the September core update. You can see in the attached image the overall downturn in organic in 2019 with a larger hit in September bringing Google Organic traffic down around 50%. There are many concerning incoming links from 50-100 obviously spammy porn-related websites to just plain old unnatural links. There was no effort to purchase any links so it's unclear how these are created. There are also 1,000s of incoming external links (most without no-follow and similar/same anchor text) from yellowpages.com. I'm trying to get this fixed with them and have added it to the disavow in the meantime. I'm focusing on internal links as well with a more specific question: If I have a sitewide header on a blog located at blog.domain.com that has links to various sections on domain.com without no-follow tags, is this a possible source of the traffic drops and algorithm impact? The header with these links is on every page of the blog on the previously mentioned subdomain. **More generally, any advice as to how to turn this around? ** The website is in the travel vertical. 90BJKyc

Domain change after over optimisation
Hi Guys, Wanted to get some second opinions. I have a client who worked with someone on their SEO for about 15months, during which time they reaped the benefits of being top of Googles organic rankings for their main keyword. Unfortunately, the link building that was completed was terrible with no care taken for future updates, over optimised anchor text links on totally irrelevant websites. Contacting webmasters in order for links to be taken down was an impossible task, these websites were pure spam sites which I doubt anyone oversees with any care. So went the disavow route, it caused a slight increase, but the way Google indexes the website and its pages is still all over the place. We have a good new content marketing plan in place for the next 12 months, and already have some great in depth articles, videos and interactive infographics created, but the problem is my client really needs some quick wins and cannot risk the domain never recovering fully from the issues. They own the .com version of the .co.uk they have so my thoughts at this point are to move them to the .com, and the new content strategy can be worked on as if its a new project. For the keywords they target there are sites on the 1st and 2nd page with DA of 16-18, so it wont take long with the new content we have to get them back to a level playing field with the competition. The one worry I do have is Google seeing the .co.uk go down, and the .com appear with the same website on and looking down on the "start from scratch" method.... does anyone know of any examples when they have acted on this? We started an AdWords account (very small spend) and this has been going to the .co.uk, if we start a new one, with same billing info going to the .com could that also cause problems? So basically, because of my clients situation, and the level the competition is it, moving to the .com seems like the best move, its just whether there is any risk involved. I've never read of there being any, but thought I'd get some opinions before comitting to it. By the way, I'm only seeing this as a feasible option as they can still keep branded traffic due to buying both domains at the same time. Thanks in advance.

Will implementing 301's on an existing domain impact massively on rankings?
Hi Guys,I have a new SEO client who only has the non-www domain setup for GWT and I am wondering if implementing a 301 for www will have a massive negative impact on rankings. I know a percentage of link juice and PageRank will be affected. So my question is: If I implement the 301 should I brace myself for a fall in rankings. Should I use a 301 instead to maintain link juice and PageRank? Is it good practice to forward to www? Or could I leave the non www in place and have the www redirect to it to maintain the data? Dave

Mobile SEO best practices : Should my mobile website be located at m.domain.com or domain.com/mobile?
I'd like to know if there's any difference between using m.domain.com/pages or domain.com/mobile/pages for a mobile website? Which one is better? Why? Does Google treat the two differently? As you can see, I'm new to this! This is my first time working on a mobile website, so any links/resources would be highly appreciated. Thanks!

SEO for location outside major city
Hello, I'm hoping to get some opinions on optimising a site for a client based 30 minutes outside of Dublin. Obviously there is a higher search volume for "x in Dublin" than "x in small town". What do you think the best strategies are for incorporating the "Dublin" into keywords? For example is it OK to use phrases like "x near Dublin" or "x in Greater Dublin", or do you think this is a bit misleading? The client in question sells good online, so the customer wouldn't physically have to visit the store. Thanks!

Best way to handle SEO error, linking from one site to another same IP
We committed an SEO sin and created a site with links back to our primary website. Although it does not matter, the site was not created for that purpose, it is actually "directory" with categorized links to thousands of culinary sites, and ours are some of the links. This occurred back in May 2010. Starting April 2011 we started seeing a large drop in page views. It dropped again in October 2011. At this point our traffic is down over 40% Although we don't know for sure if this has anything to do with it, we know it is best to remove the links. The question is, given its a bad practice what is the best fix? Should we redirect the 2nd domain to the main or just take it down? The 2nd domain does not have much page rank and I really don't think many if any back-links to it. Will it hurt us more to lose the 1600 or so back links? I would think keeping the links is a bad idea. Thanks for your advice!

Ever seen a black hat SEO hack this sneaky?
A friend pointed out to me that a University site had been hacked and used to gain top Google rankings. But it was cloaked so that most users wouldn't notice the hack. Only Googlebot and visitors from Google SERPs for the spam keywords would see a hacked version. See http://www.rypmarketing.com/blog/122-how-hackers-gained-an-easy-1-google-ranking-using-a-university-website.whtml (my blog) for screenshot and specifics. I've dealt with hacks before, but nothing this evil and sneaky. Ever seen anything like this? This is not our client, but was just curious if others had seen a hack like this before.
