<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. __

Does having a sub-domain on a different server affect SEO?
I'm working with a company that has a hard-coded website on the root domain, and then a WordPress blog on a subdomain on a separate server. We're planning on implementing a hub and spoke model for their content, hosting the main hubs on the root domain and the linked articles on the blog. Is having the blog on a different server going to hinder our SEO efforts?

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!

Do I use /es/, /mx/ or /es-mx/ for my Spanish site for Mexico only
I currently have the Spanish version of my site under myurl.com/es/ When I was at Pubcon in Vegas last year a panel reviewed my site and said the Spanish version should be in /mx/ rather than /es/ since es is for Spain only and my site is for Mexico only. Today while trying to find information on the web I found /es-mx/ as a possibility. I am changing my site and was planning to change to /mx/ but want confirmation on the correct way to do this. Does anyone have a link to Google documentation that will tell me for sure what to use here? The documentation I read led me to the /es/ but I cannot find that now.

Use of title tags on divs for SEO purposes

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 -
Can you have a /sitemap.xml and /sitemap.html on the same site?
Thanks in advance for any responses; we really appreciate the expertise of the SEOmoz community! My question: Since the file extensions are different, can a site have both a /sitemap.xml and /sitemap.html both siting at the root domain? For example, we've already put the html sitemap in place here: https://www.pioneermilitaryloans.com/sitemap Now, we're considering adding an XML sitemap. I know standard practice is to load it at the root (www.example.com/sitemap.xml), but am wondering if this will cause conflicts. I've been unable to find this topic addressed anywhere, or any real-life examples of sites currently doing this. What do you think?

How does Google find /feed/ at the end of all pages on my site?
Hi! In Google Webmaster Tools I find *.../feed/ as a 404 page in crawl errors. The problem is that none of these pages exist and they have no inbound links (except the start page). FYI, it´s a wordpress site. Example: www.mysite.com/subpage1/feed/ www.mysite.com/subpage2/feed/ www.mysite.com/subpage3/feed/ etc Does Google search for /feed/ by default or why do I keep getting these 404´s every day?

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
