<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. __

Duplicate content issue with ?utm_source=rss&utm_medium=rss&utm_campaign=
Hello,
Technical SEO | | Dinsh007
Recently, I was checking how my site content is getting indexed in Google and from today I noticed 2 links indexed on google for the same article: This is the proper link - https://techplusgame.com/hideo-kojima-not-interested-in-new-silent-hills-revival-insider-claims/ But why this URL was indexed, I don't know - https://techplusgame.com/hideo-kojima-not-interested-in-new-silent-hills-revival-insider-claims/?utm_source=rss&utm_medium=rss&utm_campaign=hideo-kojima-not-interested-in-new-silent-hills-revival-insider-claims Could you please tell me how to solve this issue? Thank you1 -
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

SEO plugin by Yoast messing up my title/meta description
Hey guys, I'm having some issues with my wordpress blog, and I believe SEO plugin by Yoast could be the one causing it. I have set a title for my wordpress blog, and a tagline. This was set in dashboard > settings > general Under "titles and metas" > home in the plugin it says, title: %%sitename%% %%page%% %%sep%% %%sitedesc%%, and meta description is blank. The reports on seomoz says my title is title+meta description - making it to long (to many characters). What could be the issue here? Thanks in advance!

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?
