<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. __

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

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!

Isnt it better to have headlines in H1 and H2 tags instead of p tags?
I am working with a simple site http://http://lightsigns.com/Uniko_Manufacturing_Limited.html They seek more SEO traffic. However, the two big headlines that read "Wholesale Supply to the Sign and Display Industries" which is on line 241 and 242 of the source code, its in a p tag, i.e. <p <span class="webkit-html-tag">style</p <span>="padding-top: 0pt; " class="paragraph_style_1">Wholesale Supply to the and <p <span class="webkit-html-tag">style</p <span>="padding-bottom: 0pt; " class="paragraph_style_1">Sign and Display Industries Likewise, the product titles are in p tags, also. For example, on the Slide-in Light Box product page, http://lightsigns.com/Slide_In_light_box.html , I have done keyword research and no one is using the words slide in light box.Plus, it is also a p tag, ie. line 43 reads style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style">Slide-in Light Box If I suggest that they make an H2 tag with SEO-optimized keywords such as Display Light Box - Slide-In LIght Box, would this indeed help SEO? In summary, is it correct to say that H1 and H2 tags are stronger signals to the search bots of what the page is about?
