<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. __

Will skipping <H> tags affect your SEO?
Will skipping <H> tags on a page have any impact on your SEO, e.g. skipping a <H2> so your page has a <H1> and then goes to a <H3>? Obviously a page must have a <H1>, but does it matter if you skip other headings?

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?

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

Express js and SEO?
Hi fellow Mozzers, I have been tasked with providing some SEO recommendations for a website that is to be built using express.js and Angular. I wondered whether anyone has had any experience in such a framework? On checking a website built in this and viewing as a GoogleBot etc using the following tools it appears as though most of the content is invisible: http://www.webconfs.com/search-engine-spider-simulator.php http://www.browseo.net/ Obviously this is a huge issue and wonder if there are any workarounds, or reccomendations to assist (even if means moving away from this - would love to hear about it)

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.

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
