<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!

Exact Match Domain & Title Tag / URL
I currently own an exact match domain for my keyword. I have it set up with multiple pages and also a blog. The home page essentially serves as a hub and contains links to all the pages and the blog. My targeted keyword is on its own page and I made the title tag the same as my keyword. As an example the URL for my targeted post looks like this: benefitsofrunningshoes.com/benefits-of-running-shoes I have solid, non-spammy content and clean whitehat earned backlinks directing to that specific page. My concern right now is that the URL looks kinda spammy. The website has been live for about a week and the home page ranks well enough but my targeted page is no where to be found. (it does show up if I manually search via search command "site:benefitsofrunningshoes.com"). I'm wondering if it is acceptable to use the exact keyword in title tag / page url if it is also in the domain as an EMD? Should I change the title tag and leave the URL in? Or should I completely change the title tag and URL and 301 redirect to the new page? I appreciate any help!

Title Tag vs. H1 / H2
OK, Title tag, no problem, it's the SEO juice, appears on SERP, etc. Got it. But I'm reading up on H1 and getting conflicting bits of information ... Only use H1 once? H1 is crucial for SERP Use H1s for subheads Google almost never looks past H2 for relevance So say I've got a blog post with three sections ... do I use H1 three times (or does Google think you're playing them ...) Or do I create a "big" H1 subhead and then use H2s? Or just use all H2s because H1s are scary? 🙂 I frequently use subheads, it would seem weird to me to have one a font size bigger than another, but of course I can adjust that in settings ... Thoughts? Lisa

Setting title tag with javascript/jquery
Hi there, I'm looking for some advice. I've recently implemented a few jQuery functions which gets specific content from the page and then sets the title and description. See working example here. It seems to work fine but my question I have is whether Google bots can read it and whether it might actually hinder my SEO efforts? Any advice would be really appreciated! Peter

Use of title tags on divs for SEO purposes
Hello community, I recently was asked by a client to analyze a website of a competitor. I did was he asked me to do but when I looked at the source code of the website I found this code: I changed the exact words into something for privacy reasons, but I never looked at a code like this.

Using a div for an anchor I get but adding a title tag to the div? I never seen that before. Title tags on anchors, yes, using images in divs as background and then adding a title??? Does anyone have any experience with a code like this and if you do how does this impact rankings? Does it impact rankings at all and does anybody know of any correlation between the two? Looking forward for your responses. Regards Jarno0 -

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. Kind Regards Phil Scott Vida Homes0 -
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.
