<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. __

SEO advice on ecommerce url structure where categories contain "/c/"
Hi! We use Hybris as plattform and I would like input on which url to choose. We must keep "/c/" before the actual category. c stands for category. I.e. this current url format will be shortened and cleaned:

https://www.granngarden.se/Sortiment/Husdjur/Hund/Hundfoder-%26-Hundmat/c/hundfoder To either: a.
https://www.granngarden.se/husdjur/hund/hundfoder/c/hundfoder b.
https://www.granngarden.se/husdjur/hund/c/hundfoder (hundfoder means dogfood) The question is whether we should keep the duplicated category name (hundfoder) before the "/c/" or not. Will there be SEO disadvantages by removing the duplicate "hundfoder" before the "/c/"? I prefer the shorter version ofc, but do not want to jeopardize any SEO rankings or send confusing signals to search engines or customers due to the "/c/" breaking up the url breadcrumb. What do you guys say and prefer from the above alternatives? Thanks /Hampus0 -
Do H2 tags carry more weight than h4 tags?
Of course H tags are key signals for relevance in search. Does an h2 tag send a significantly "louder" signal than an h4 tag?

Shopping Carts & Sub Domains
I was hoping someone could guide me in making the correct decision regarding integrating my existing domain with a hosted shopping cart. I have an existing website to promote my bricks and mortar retail operation and am expanding into web retailing. I will be using one of the major hosted shopping carts. What is the best way to join the two components from an SEO perspective? Have the cart as a sub domain of my main site, or move my existing domain name to be hosted by the cart provider and have both components operate under the same general domain? I have read arguments that putting your cart within a sub domain is not a good idea because any clout of the pre-existing domain will not be shared with the sub domain; that they will be treated as two separate sites. I have also read that using a sub domain is a good idea being that the content focus of the main domain (marketing and blogs) is different form the focus of the sub domain (product sales), and that the two components would benefit form earning their own rankings undiluted by the other. And, I have also read that search engines are getting good at being able to deduce that an eCommerce sub domain is legitimate extension of a content intensive main domain, and that they treat the two components as a combined whole. What is the truth? Which is the better way to go? Any guidance would be appreciated.

Cloudflare Email Address Protecting & SEO
I have a client who uses Cloudflare to protect their email address on their website from spam and when I crawl their site looking for errors it causes it to report multiple broken links on each page. Does anyone know how this impacts SEO? Should I recommend removing Cloudflare?

OK to block /js/ folder using robots.txt?
I know Matt Cutts suggestions we allow bots to crawl css and javascript folders (http://www.youtube.com/watch?v=PNEipHjsEPU) But what if you have lots and lots of JS and you dont want to waste precious crawl resources? Also, as we update and improve the javascript on our site, we iterate the version number ?v=1.1... 1.2... 1.3... etc. And the legacy versions show up in Google Webmaster Tools as 404s. For example: http://www.discoverafrica.com/js/global_functions.js?v=1.1

http://www.discoverafrica.com/js/global.js?v=1.2
http://www.discoverafrica.com/js/jquery.validate.min.js?v=1.1
http://www.discoverafrica.com/js/json2.js?v=1.1 Wouldn't it just be easier to prevent Googlebot from crawling the js folder altogether? Isn't that what robots.txt was made for? Just to be clear - we are NOT doing any sneaky redirects or other dodgy javascript hacks. We're just trying to power our content and UX elegantly with javascript. What do you guys say: Obey Matt? Or run the javascript gauntlet?0 -
Do we need to manually submit a sitemap every time, or can we host it on our site as /sitemap and Google will see & crawl it?
I realized we don't have a sitemap in place, so we're going to get one built. Once we do, I'll submit it manually to Google via Webmaster tools. However, we have a very dynamic site with content constantly being added. Will I need to keep manually re-submitting the sitemap to Google? Or could we have the continually updating sitemap live on our site at /sitemap and the crawlers will just pick it up from there? I noticed this is what SEOmoz does at http://www.seomoz.org/sitemap.

What is the best method to block a sub-domain, e.g. staging.domain.com/ from getting indexed?
Now that Google considers subdomains as part of the TLD I'm a little leery of testing robots.txt with something like: staging.domain.com
Technical SEO | | fthead9
User-agent: *
Disallow: / in fear it might get the www.domain.com blocked as well. Has anyone had any success using robots.txt to block sub-domains? I know I could add a meta robots tag to the staging.domain.com pages but that would require a lot more work.0
