<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. __

Coming soon SEO
Hi, I was wondering what is the best practice to redirect all the links juice by redirecting all the pages of your website to a coming soon page. The coming soon page will point to the domain.com, not to a subfolder. Should I move the entire website to a subfolder and redirect this folder to the coming soon page? Thanks

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

Shopping Carts & Sub Domains
I was hoping someone could guide me in making the correct decision regarding integrating my existing domain with a hosted shopping cart. I have an existing website to promote my bricks and mortar retail operation and am expanding into web retailing. I will be using one of the major hosted shopping carts. What is the best way to join the two components from an SEO perspective? Have the cart as a sub domain of my main site, or move my existing domain name to be hosted by the cart provider and have both components operate under the same general domain? I have read arguments that putting your cart within a sub domain is not a good idea because any clout of the pre-existing domain will not be shared with the sub domain; that they will be treated as two separate sites. I have also read that using a sub domain is a good idea being that the content focus of the main domain (marketing and blogs) is different form the focus of the sub domain (product sales), and that the two components would benefit form earning their own rankings undiluted by the other. And, I have also read that search engines are getting good at being able to deduce that an eCommerce sub domain is legitimate extension of a content intensive main domain, and that they treat the two components as a combined whole. What is the truth? Which is the better way to go? Any guidance would be appreciated.

How does Google find /feed/ at the end of all pages on my site?
Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?

Do we need to manually submit a sitemap every time, or can we host it on our site as /sitemap and Google will see & crawl it?
I realized we don't have a sitemap in place, so we're going to get one built. Once we do, I'll submit it manually to Google via Webmaster tools. However, we have a very dynamic site with content constantly being added. Will I need to keep manually re-submitting the sitemap to Google? Or could we have the continually updating sitemap live on our site at /sitemap and the crawlers will just pick it up from there? I noticed this is what SEOmoz does at http://www.seomoz.org/sitemap.

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!
