<sub>& <sup>tags, any SEO issues?</sup></sub>
-
Hi - the content on our corporate website is pretty technical, and we include chemical element codes in the text that users would search on (like S02, C02, etc.) A lot of times our engineers request that we list the codes correctly, with a <sub>on the last number. Question - does adding this code into the keyword affect SEO? The code would look like SO<sub>2</sub>.</sub>
Thanks.

Hi Jenny
jStrong is correct. Subscript (<sub>) and superscript (<sup>) tags are not going to have any effect (positive or negative) on SEO.</sup></sub>

Hi Jenny,
I don't think these tags would have any affect on the SEO. They are formatting tags the same as _or _that only affect the styling of the text they surround and it is unlikely that when crawled they are treated as anything but that. __

Does having a sub-domain on a different server affect SEO?
I'm working with a company that has a hard-coded website on the root domain, and then a WordPress blog on a subdomain on a separate server. We're planning on implementing a hub and spoke model for their content, hosting the main hubs on the root domain and the linked articles on the blog. Is having the blog on a different server going to hinder our SEO efforts?

What do you do with product pages that are no longer used ? Delete/redirect to category/404 etc
We have a store with thousands of active items and thousands of sold items. Each product is unique so only one of each. All products are pinned and pushed online ... and then they sell and we have a product page for a sold item. All products are keyword researched and often can rank well for longtail keywords Would you :- 1. delete the page and let it 404 (we will get thousands) 2. See if the page has a decent PA, incoming links and traffic and if so redirect to a RELEVANT category page ? ~(again there will be thousands) 3. Re use the page for another product - for example a sold ruby ring gets replaces with ta new ruby ring and we use that same page /url for the new item. Gemma

Using a div for an anchor I get but adding a title tag to the div? I never seen that before. Title tags on anchors, yes, using images in divs as background and then adding a title??? Does anyone have any experience with a code like this and if you do how does this impact rankings? Does it impact rankings at all and does anybody know of any correlation between the two? Looking forward for your responses. Regards Jarno0 -
/~username
Hello, The utility on this site that crawls your site and highlights what it sees as potential problems reported an issue with /~username access seeing it as duplicate content i.e. mydomain.com/file.htm is the same as mydomain.com~/username/file.htm so I went to my server hosts and they disabled it using mod_userdir but GWT now gives loads of 404 errors. Have I gone about this the wrong way or was it not really a problem in the first place or have I fixed something that wasn't broken and made things worse? Thanks, Ian

Tutorial For Moving Blogger Blog From Sub-Domain to Sub-Directory
Does anyone know where I can find a tutorial for moving a blogger.com (blogspot) blog that's currently hosted on a subdomain (i.e. blog.mysite.com) to a subdirectory (i.e. mysite.com/blog) with the current version of blogger? I'm working on transferring my blogger blogs over to wordpress, and to do so without losing link juice or traffic, this is one of the steps I have to take. There's plenty of tutorials that address moving from blogspot.mysite.com to wordpress and I've even found a few that address moving from blog.mysite.com (hosted on blogger) to a root domain mysite.com. However, I need to move from blog.mysite.com (blogger) to mysite.com/blog/ - subdirectory (wordpress). Anyone who knows how to do this or can point me in the right direction?? Thanks.

Do I need to add canonical link tags to pages that I promote & track w/ UTM tags?
New to SEOmoz, loving it so far. I promote content on my site a lot and am diligent about using UTM tags to track conversions & attribute data properly. I was reading earlier about the use of link rel=canonical in the case of duplicate page content and can't find a conclusive answer whether or not I need to add the canonical tag to these pages. Do I need the canonical tag in this case? If so, can the canonical tag live in the HEAD section of the original / base page itself as well as any other URLs that call that content (that have UTM tags, etc)? Thank you.

DISQUS COMMENTS backlinks-good for seo? YES/NO?
DISQUS COMMENTS backlinks-good for seo? YES/NO? I have just started commenting on "powered by disquus" websites in the Disqus comments box and left a link to my website in the name field! Having googled whether Disqus comments backlinks are any good for seo purposes i have discovered that there is a 50/50 view on the subject with some people saying they are a "goldmine" for getting high PR backlinks and others saying they are a waste of time because googlebot cannot read Java. My own experience of commenting on Disqus powered websites is that wordpress blogs powered by disqus comments ARE INDEXED by GOOGLE and the "BACKLINK IS IN THE SOURCE OF THE PAGE" When i comment on normal websites using the Disqus comment system i have found that my Disqus comments ARE NOT indexed by Google and there IS NO BACKLINK in the page source! Has anybody got any views on whether Disqus comments backlinks are any good?

Iframes & SEO
I've got a client that wants a site with all content in iFrames. They saw another site they liked & asked if we could do it. Of course we can technically. How big a negative hit would they take with SEO? Is there anything we can do to mitigate it, such as redirects, etc? Thanks for the help!
