Do more links from sub-domains to domain (website) hurt rankings?
-
Hi all,
If there are multiple sub-domains like abc.website.com, 123.website.com, etc...and if the top pages of website are linked from multiple sub-domains via top menu or footer links; will this hurts?
Will too much interlinking of few top pages of a website from it's sub-domains dilute link juice?
How many links ideally we can add to website from a sub-domain?
Thanks

Hi there,
There isn't a definitive answer regarding the number of links that you should add. The way I'd suggest thinking about this is what would make sense for users - do they need to have links on every single page? Does it make sense for them to be able to click to different subdomains from anywhere or could you list them all on your homepage or another page?
It's pretty common practice to cross link between subdomains that are related to each other, but you do want to be careful not to do it if it doesn't make sense i.e. if you're doing it just for SEO benefit, it's worth considering if it's the right thing to do. It's also worth avoiding a focus on keyword driven anchor text, because that could definitely be seen as manipulative if you overdo it.
I hope that helps!

Core Web Vitals hit Mobile Rankings
Hey all, Ever since Google announced "Core Web Vitals" are mobile rankings have nose-dived. At first, I thought it was optimisation changes to the page titles we had made which might still be part of the issue. However, Desktop rankings actuallyy increased for the same pages where mobile decreased. There is the plan to introduce a new ranking signal into the Google algorithm called the "core web vitals: and this was discussed around late May. even though it's supposed to get fully indexed into a ranking signal later this year or early next; I think Google continuously test and release this items before any official release. If you weren't aware, there is a section in Google Webmaster Tools related to "core web visits", which looks at:1. Loading2. Interactivity3. Visual StabilityThis overlays some of the other basic requirements of a good website and mobile experience. Taking a look at our Google Search Console, it appears to be the following:1. Mobile- 1,006 poor URLs, 100URLs need improvement and 475 good URLs.2. desktop- 0 poor URLs, 379 need improvements and 1,200 good URLsSOURCE: https://search.google.com/search-console/core-web-vitals?resource_id=https%3A%2F%2Fwww.griffith.ie%2FIn the report, we can see two distinct issues with the mobile pages:CLS Issue: more than 0.25 (mobile)- 1,006 casesLCP issue: longer than 4secs (mobile) - 348 case_CLS (Cumulative Layout Shift)This is a developer issue, and needs fixing. It's basically when a mobile screen jumps for the user. It is explained in this article: https://web.dev/cls/Seems to be an issue with all pages. **LCP (Largest Contentful Paint)_**Again, another developer fix that needs to be implemented. It's connected to page speed, and can be viewed here: https://web.dev/lcp/Looking at GCS, it looks like the blog content is mostly to blame.It's worth fixing these issues and again looking at the other items on page speed score tests:1. Leverage browser caching- https://gtmetrix.com/reports/griffith.ie/rBtvUC0F2. https://developers.google.com/speed/pagespeed/insights/?url=griffith.ie- mobile score for home page is 16/100, https://www.griffith.ie/people/thamil-venthan-ananthavinayagan is 15/100I think here is the biggest indicator of the issue at hand. Has anybody else noticed their mobile rankings go down and desktop stay the same of increase.Kind regards,

Any risks involved when we have huge list of redirects in our website database?
Hi all, We have changed hundreds and thousands of page and page URLs for last 10 years in our website. So, now we are going to redirect most of the old pages/links to the current related pages. This will increase the number of redirects we set in our website database to thousands. Will this put any extra weight on crawler and any risks involved for employing too many redirects. Thanks

Client has franchisees on separate sub domains
Hi, a large client of mine has all of his franchisee network on sub domains and on separate wordpress websites (multi-sites). I have advised him that the best way forward is to use the main company .com domain and create sub folders for all of his franchisee areas. Does anyone foresee any problems with this going forward or do you have any advice to offer. I'd be interested in hearing what your verdict is on the subdomain vs subfolder war. Many thanks

Does a Website Overlay Hurt Ranking?
We are looking into personalizing visits on our website. Rather than to write Tb of code on each page, we want to use a little line of Java script on the page, that would allow to place overlay on the site, depending on the visitor. Example: Change the home page picture when a returning visitor comes back on the website and show him/her a different picture bases upon the pages he/she visited prior. Would that overlay be caught by Google and would G have a problem with that? We all know about cloaking, but G does not penalize for heat mapping overlays, for example. Or not to my knowledge they don't. Thanks all for your personal insights! Peter

Parallax websites - good for SEO?
A client of mine is redesigning their site using a vertical Parallax & upon doing some research I've stumbled across Drew Barrymore's site: http://flowerbeauty.com/ - which also uses Parallax. What I like in particular is that the site changes URLs as you scroll down. If you go direct to one of those URLs you'll notice unique meta data (albeit poorly optimised). All pages are indexed fine in Google (https://www.google.com/#bav=on.2,or.r_cp.r_qf.&fp=f8873f78dfbb8c5e&q=site:flowerbeauty.com) I'm just wondering if this is considered ok as the user experience is good and they're not doing anything manipulative, however, there's duplicate content and a potential case of cloaking at hand. I think this approach may be ok for my client for a product features page or a global office locations page since I can break up the sections nicely and split a really long page featuring a lot of content into separate URLs. Whereas Flower Beauty have done it across the whole site... i.e. one page of HTML = the whole site. What do you guys think?
