<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. __

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!

Canonical tag for Home page: with or without / at the end???
Setting up canonical tags for an old site. I really need advice on that darn backslash / at the end of the homepage URL. We have incoming links to the homepage as http://www.mysite.com (without the backslash), and as http://www.mysite.com/ (with the backslash), and as http://www.mysite.com/index.html I know that there should be 301 redirects to just one version, but I need to know more about the canonical tags... Which should the canonical tag be??? (without the backslash) or (with the backslash) Thanks for your help! 🙂

SEO plugin by Yoast messing up my title/meta description
Hey guys, I'm having some issues with my wordpress blog, and I believe SEO plugin by Yoast could be the one causing it. I have set a title for my wordpress blog, and a tagline. This was set in dashboard > settings > general Under "titles and metas" > home in the plugin it says, title: %%sitename%% %%page%% %%sep%% %%sitedesc%%, and meta description is blank. The reports on seomoz says my title is title+meta description - making it to long (to many characters). What could be the issue here? Thanks in advance!

Robots.txt to disallow /index.php/ path
Hi SEOmoz, I have a problem with my Joomla site (yeah - me too!). I get a large amount of /index.php/ urls despite using a program to handle these issues. The URLs cause indexation errors with google (404). Now, I fixed this issue once before, but the problem persist. So I thought, instead of wasting more time, couldnt I just disallow all paths containing /index.php/ ?. I don't use that extension, but would it cause me any problems from an SEO perspective? How do I disallow all index.php's? Is it a simple: Disallow: /index.php/

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/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 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.
