Rankings of Subdomains vs. Main Domain
-
Here's a puzzler...
Our main domain (www.ides.com) doesn't appear in Google (but does on Bing and other engines). We think this is due to duplicate content which we're fixing.
However our website's subdomains continue to appear prominently in SERPs, even on Google - here are some examples:
- IDES Prospector = prospector.ides.com
- IDES = support.ides.com
- Cycolac FR15 = catalog.ides.com
Why would Google penalize a main domain and its subdomains?

Maybe the robots problem fixes everything for you. I hope it does.
I always use the same kind of robots.txt -> as short as possible and as clear as possible. Archives and everything are allowed and so far (knocking on a piece of natural wood) never has something like this occurred. Again hope this helps your site
kind regards

Thanks Jarno,
Good to know from your geographic location. Looking at analytics shows traffic is down about 60% from Google visits originating from the U.S. to our main domain.
The last ia_archiver blocks an archiving website - saw it in Bruce Clay's robots.txt (http://www.bruceclay.com/robots.txt).
But we are looking at cleaning up our robots.txt file so it's nice 'n tidy. There are things in there that can now be removed, so thank you for the reminding tip!
No errors in Google Webmaster. Did receive a message on Nov. 5th saying http://www.ides.com/: Big traffic change for top URL but no reasons listed.

Nathan,
i just checked it but Google has listed your website:
If you were truly penalized i don't think i would get the results I'm getting now. Have you checked your robots.txt file for any strange markings? strange signs or number sequences? When i look at it it looks like this:

Disallow: /Maybe this last statement is confusing Google? i have never seen a ia_archiver disallow root statement before. Is it the right syntaxis?
What are your webmastertools saying? Any strange errors or messages?
Kind Regards
Jarno

Company name ranking
Hi all, I hope somebody can share their thoughts on the below. A web designer launched my client's new website and I have been tasked with the SEO. I was approached with an immediate problem, www.clientswebsite.co.uk was ranking 9th for their company name after being indexed by Google. The search results above www.clientswebsite.co.uk were related to my client but not all, for example a direct competitor was also ranking. I have been working on the SEO for 2-3 weeks and I just managed to get to 3rd position for the company name, and then www.clientswebsite.co.uk disappeared from page 1! And now instead, an irelevant sub page is now ranking for the company name on page 2 (a contact page). I have checked and the home page is still indexed (did a site: check). The only problem software picks up is a redirect chain (http://homepage -> http://www.homepage -> https://homepage) the web developers said it wouldn't impact rankings (when I asked them to edit the htaccess file to fix it) I've listed below the SEO tasks I completed whilst attempting to rank the company name: I set up analytics and webmaster tools, in which I set up preferred domain (www) Added a sitemap Edited meta data making sure company name was included I contacted the websites above www.clientswebsite.co.uk that were relevant and asked them to place a link linking to their new website, I was successful with a couple of these. I placed www.clientswebsite.co.uk on all of their social media profiles I reformatted headers on their home page, making sure the H1 included my client's company name I found 2 extra versions of my client's home page (not exact copies, but very similar content) that had been published, so I decided to 301 redirect these to the correct home page Activated SSL and forced to HTTPS I would really appreciate it if anyone could share their thoughts here, whether it be explanations or possible solutions Adam

Ranking in Bing
My frustration with Google currently has led me to try bing out more. I don't rank as good in bing as Google, so I was wondering if anyone had any great tips of what bing looks for to rank website well? So far I can see they seem to favour keyword domains, take 'cheap holidays' for example. Always reading about what Google want but what do bing want? Any advice much appreciated.

What should the combined domain rank of 2 sites?
We have just combined 2 sites by redirecting a site with a domain ranking of 35 to a site with a domain ranking of 27 (this is because the we want to use the address with a ranking of 27) After a week I now have 1 domain with a ranking of 26?? So my questions are; Should the ranking have increased already? What should I expect the ranking to increase to if at all? Is there something I could have done wrong when transferring? Thanks

Domain Registrar
Looking for opinions on some good domain registrars since I have decided to transfer from Godaddy. A question while I'm here discussing the topic. Does the reputation of a Domain Registrar affect SEO in any form?

Malware ranking drops
Hi, One of our sites got hit with malware in November. We cleaned it up and sent a reconsideration request and no malware warnings are in WMT anymore. We still haven't seen an improvement in rankings even though people say it can take up to 90days? Organic traffic is down 40% and still dropping. Any advice? Thanks

Change of domain name?
Hello, We are currently developing a new site for an existing online clothing retailer. The existing site is on a .co.uk domain, however we are targeting a global market and wondered whether we could/should launch the new site under a .com address and whether this would be beneficial? Most of our back links come from Affiliate blogs and we could quite easily change these to the new URL. Thanks Bilal

Changing Domain Registrars have an affect on rankings?
So, I just wanted to move my domain from GoDaddy to NameCheap. I am still thinking about the move as I am not sure what affect it will have on my rankings. Has anyone here done it before? Did you see any drop in rankings? Also, while I was at it - I was thinking maybe I can add WhoisGuard too. I am not too paranoid about people getting my info from WhoIs, but does having a private Whois have an affect on ranking?
