<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. __

Multiple CMS on one website / domain & SEO
For a client we would like to work with a content hub, but their website is build on a custom CMS so we are limited in our options and if we aks their web developers they ask crazy prices to help us. So now we have the idea to build the content hub with wordpress and implement it next to their current CMS. for example on www.website.com/contenthub/ . As far as i know this is technically possible and there are no negative effects regarding SEO as long as we link the two sitemaps together. Am i right or am i missing something here?

Schema for Banks and SEO
I'm researching Schema opportunities for a bank, but besides the shema markup available today (like bankorcreditunion) and developments with FIBO, I can find no answer as to the effect of tagging interest rates and such in terms of SERP/CTR performance or visibility. Does anyone have a case study to share or some insight on the matter?

Multilingual Website - Sub-domain VS Sub-directory
Hi Folks - Need your advice on the pros and cons of going with a sub-domain vs a sub-directory approach for a multi lingual website. The best would be a ccTLD but that is not possible now, so I would be more interested in knowing your take on these 2 options. Though, I have gone through http://www.stateofsearch.com/international-multilingual-sites-criteria-to-establish-seo-friendly-structure/ and this somewhat vouches for a sub-directory, but what would you say'?

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -

Using hyphenated sub-domains or non-hyphenated sub-domains? What is the question! I Any takers?
For our corporate business level domain, we are exploring using a hyphenated sub-domain foir a project. Something like www.go-figure.extreme.com I thought from a user perspective it seems cluttered. The domain length might also be an issue with the new Algorithm big G has launched in recent past. I know with past experience, hyphenated domains usually take longer to index, as they are used by spammers more frequently and can take longer to get out of the supplementary index. Our company site has over 90 million viewers / year, so our brand is well established and traffic isn't an issue. This is for a corporate level project and I didn't have the answer! Will this work? anyone have any experience testing this. Any thoughts will help! Thanks, Rob
