<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. __

If I change Tags and Categories in Wordpress blog post, will it negatively affect SEO and cause 404s?
Hi, I have belatedly come to the conclusion that I have been using tags and categories when blogging in wordpress incorrectly. The result is that Google seems to prefer to show my archives and tags in search results rather than the post itself. Not good UX. As the site is only a few months old, am I best to learn my lesson and tag and categorize correctly moving forward or Should I go back in to these posts and clean them up & categorize and tag correctly. If I do this, will it cause 404s and hurt my SEO? Thanks!

My Homepage Won't Load if Javascript is Disabled. Is this an SEO/Indexation issue?
Hi everyone, I'm working with a client who recently had their site redesigned. I'm just going through to do an initial audit to make sure everything looks good. Part of my initial indexation audit goes through questions about how the site functions when you disable, javascript, cookies, and/or css. I use the Web Developer extension for Chrome to do this. I know, more recently, people have said that content loaded by Javascript will be indexed. I just want to make sure it's not hurting my clients SEO. http://americasinstantsigns.com/ Is it as simple as looking at Google's Cached URL? The URL is definitely being indexed and when looking at the text-only version everything appears to be in order. This may be an outdated question, but I just want to be sure! Thank you so much!

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?

Same H1 & H2 Tags
Is it bad to have the same H1 & H2 tag on one page? I found a similar question here on the moz forum but it didn't exactly answer my question. And will adding "about" on the H2 help, or should we avoid duplicate tags completely? Here is a link to the page in question (which will repeat throughout this site.) Thanks in advance!

Duplicate Title Tag issue due to Shopify CMS
Hi guys, I'm a novice really when it comes to SEO, yet have taken it in house for the next year or so, firstly because I have had my fingers burnt twice...and secondly, to allow me to recoup some of the loss from my prior campaigns. One thing I have noticed on my site (which uses a Shopify E-commerce CMS), is that Shopify duplicates a url for each my products. An example of this is http://www.vidahomes.co.uk/collections/designer-radiators-heating/products/reina-aliano

http://www.vidahomes.co.uk/products/reina-aliano Both products provide exactly the same information, yet appear in different ways subject to how the customer finds them. I contacted Shopify to find a fix to this issue when I noticed a high amount of Duplicate Title Tags in my SEO crawl. Their response was as follows. Using a rel canonical link will help prevent duplicate content issues with search engines. All you need to do is add this line of code: **<link rel="canonical" href="{{ canonical_url }}" />** ** before the tag in the theme.liquid file. It’s that simple :)** The theme liquid file basically generates the outer template for the whole site, and is only compromised when over-ruled. This all seems a little too easy for me, so I am hoping whether someone can elaborate as to whether this will work or not, as I'm not entirely sold on their response. I was always under the impression with canonical tags, that they should be added to the header section of the duplicate page in question, which refers back to the original page. The code I have been told to add above implies that the canonical tag would be added to every page in my site so the Google robot would have a hard time in finding anything at all of relevance Thanks in advance for any assistance with this.
