sub-domain or sub-directory for mobile version
advantages or dis-advangages?
-
Ok, in my opinion mobile website are not the actual part of the main website (mobile website do not have same status as blog) so it is intelligent to go with sub domain but always keep the visitor’s sensor on so if they are coming from smart phone or ipad it should open a mobile website for them but if they are coming from desktop or laptop in that case it should be the main website for web.

domain.mobi (Subdirectory)
Pros
- Carrier transcoding. Sprint PCS in the US and Vodaphone in the UK transcode (modify websites) that you load on your phone for the best experiences (although, it breaks some websites). These carriers assume .mobi is mobile-friendly and do not modify their content.
- .mobi means mobile-friendly and is best for search: Some search engines can be set to only search .mobi domains with the assumption that they're all mobile-friendly. Although, this area is very new and search engines can determine a mobile-friendly site via other methods, this is one area of speculation.
- Brandable. Some might say that .mobi is more brand-able than m.domain.com. For instance, it's easier to tell people to go to http://domain.mobi and build a campaign around it than http://m.domain.com.
- Separate control. This might be important for an agency who is building a mobile website for a client. If they wanted to purchase and host the domain names themselves, they can. This can speed up the process for getting a domain established for the mobile site.
Cons
- Opportunity for domain squatters. Several companies own their domain.com, but they don't always own the .net/.org variations. This could either be due to never having thought about it, lack of interest, or the .net/.org being owned by a domain squatter. The domain squatter also has the opportunity to purchase domain.mobi
- More effort to type. .mobi takes longer to type than .com thanks to the .com button on most smartphones. At the end of the day, a .mobi domain isn't needed much.
- New domain, no SEO juice. A .mobi domain would be treated as a new domain name and it wouldn't take any SEO from whatever current domain you have.
- Costs involved and inconvenience. The cost of a .mobi domain and added inconvenience for managing it may not make it worthwhile.
m.domain.com(Subdomain)
Pros
- Easier to access and maintain. The DNS is all stored under the same domain. No additional domain to purchase, set up, and manage.
- Easier to type on a phone. iPhone and Android on-screen keyboards include a .com button on the virtual keyboard.
- Keeps your brand in-tact. People already know domain.com is yours. Something like domain.mobimight confuse them.
- Free. Setting up a subdomain should be a simple process depending on the web host.
- Higher adoption in the US. Companies such as Yahoo, Twitter, Google, YouTube, and Facebook have adopted this method.
- Support for multinational domains. Some companies such as Amazon have Amazon.com for their US presence and Amazon.co.uk for their UK presence. A .mobi site just comes in .mobi. I suppose you could have co.uk.amazon.mobi, but that sounds messy (and backwards). m.amazon.co.uk makes more sense.
- It's what Matt Cutts said. Matt, who works at Google and shares webmaster tips for best practices, suggested that m.domain.com will do the trick.
- _Cookie support. _This may be one of the greatest benefits of the m.domain.com method. Cookies, or temporary files on your computer used to store information, can be set for a domain and a certain subdomain. With domain.mobi, however, cookies cannot work across multiple domains. So, if you logged into a mobile website but needed to view the desktop website and wanted to switch to that mode, using m.domain.com would be best so you can stay logged in between both sites.
Cons
- Too ambiguous. Some would argue "m.domain.com" makes no sense and isn't intuitive for people looking for the mobile site.
- No carrier transcoding. Few phone carriers are transcoding websites so when someone access a site on their phone the website gets reduced in size so it loads faster. This could break some desktop websites and mobile sites. Only Sprint PCS in the US and Vodaphone in the UK are doing this that we've heard of. The work around is to manually register your mobile website as a mobile website with each carrier.
One question I often hear is which makes more sense for someone to type in, m.domain.com, or domain.mobi? My answer: if you want the mobile version, go to the desktop site and it should take you to the mobile version.
If in doubt, use m.domain.com and redirect the domain.mobi to m.domain.com.
This was the more common method of delivering a mobile optimized website before responsive design came along. You have a mobile site on a different sub-domain, such as m.bbc.co.uk, keeping all of your mobile content on different URLs.
The two most important points if you’re using this method are:
Use the rel=”alternate” tag pointing to the mobile URL on the desktop version of the page, helping Google find your mobile content.
Use the rel=”canonical” tag pointing to the desktop URL on the mobile version of the page, helping Google understand which version of the content is duplicated.
**At the last my suggestion is go with subdomain for mobile website. **

My website is not configured in AMP pages, but it is mobile-friendly.
Hi
Algorithm Updates | | rayabahadur
My website is not configured in AMP pages, but it is mobile-friendly.
Last month, my website was ranked to 10 positions for this keyword (Magento Development Company).
Sometimes it's showing on 25 positions but not in the top 5 positions. Here is my URL (for analysis):
https://www.nevinainfotech.com/magento-development-service/
Would you please explain why my keyword rankings are often not showing in the search listings?
Would you mind letting me know is there anything I need to change?

How to take down a sub domain which is receiving many spammy back-links?
Hi all, We have a sub domain which has less engagement for last few years. Eventually many spammy back links pointed to this sub domain. There are relevant back links too. We have deleted most of the pages which are employing spammy content or which have spammy back links. Still I'm confused whether to take this sub domain down or keep it. The confusion between "relevant backlinks might be helping our website" and "spammy backlinks are affecting to drop in rankings"? Thanks

Do back-links to non indexed sub-domains / sub-directories considered by Google as website backlinks and pass Pagerank to website?
Hi, If some noindexed links on our website or sub-domain got some backlinks, will that backlinks pass Pagerank / linkjuice to website? Will they be considered as backlinks to website by Google? Here is a statement from Matt cutts for the question. My question is same as below with answer? Eric Enge: Can a NoIndex page accumulate PageRank? Matt Cutts: A NoIndex page can accumulate PageRank, because the links are still followed outwards from a NoIndex page. Thanks

Different versions of keywords. Which one to optimize?
For some keywords, we have slightly different versions available. For example: people search for 'webhosting', but also for 'web hosting'. Same for 'cloudserver' and 'cloud server'. I used google trends to compare the keywords and find the more popular one. But in different countries, different keywords are searched more often. So we can't really optimize for the BEST version of the keyword, since there is no real BEST version. What would you suggest to do? We could also just develop pages for both keywords, but that could end in duplicated content. Would be an option to use canonicalization then, but this would not really improve ranking for one of the versions. I'm very confused. If anyone has a good idea on how to optimize here, please let me know. Thank you in advance! Best regards

Do Exact Match Domains Still Have Value?
I realise that there has probably been a lot said about Exact Match Domains, however, I want to know 2 things: Is this two exact match domains or one EMD: "londonfootball.com" and "footballlondon.com" so is "London Football" one EMD, and "Football London" another? Does having an EMD add a big advantage in getting ranked? Is it worth paying 2 months SEO expense to buy an EMD? To me if it still has an advantage then it probably is. However, I would like to hear the opinion of the experts. I would specially like to hear from anyone who owns or bought an EMD to rank. Thank you.

Crosslinking & Managing Multiple Domains in Same Webmaster Tool's Account
I am wondering if there are any consequences if you manage multiple websites in the same Webmaster Tool's account and cross link between them? My guess is that this would be a very easy thing for Google to detect and build into their algorithms. Hence affect the link juice from those domains that are owned by the same person. I am looking for verification on this. Thanks, Joe

301 a purchased domain
I've purchased a competitor. They rank well organically for keywords that I target, and I want to optimize the way I get value from their current rankings and traffic (and customers -- we will obviously market to their email/customer list). Which is better: (1) use a 301 redirect for any access to their domain and point it to my home page. I think this would force Google to de-index all of their pages, right? (2) put up a stub page as their homepage that announces the site has been bought, and have a do-follow link to my home page (which maybe is auto-redirected after 10 seconds or something)? Maybe this is better to keep their home page in Google's index for a while? As for option (1), I thought I read somewhere recently that 301'ing a domain to the home page of another domain would no longer pass link juice (?). Maybe I should 301 the newly purchased domain to a sub-page on my site that explains the acquisition and asks them to sign up on my site? Both sites are legit. No spamming happening here; just industry consolidation as one competitor acquires another. Thanks in advance...!

Best way of seeing how many links come from individual root domain domains.
Just wondering how best to see this - which tool to use. I'm dealing with a website with several thousand inbound links from around 100 root domains. Thanks in advance, Luke
