<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. __

Will skipping <H> tags affect your SEO?
Will skipping <H> tags on a page have any impact on your SEO, e.g. skipping a <H2> so your page has a <H1> and then goes to a <H3>? Obviously a page must have a <H1>, but does it matter if you skip other headings?

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.

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!

Using hyphenated sub-domains or non-hyphenated sub-domains? What is the question! I Any takers?
For our corporate business level domain, we are exploring using a hyphenated sub-domain foir a project. Something like www.go-figure.extreme.com I thought from a user perspective it seems cluttered. The domain length might also be an issue with the new Algorithm big G has launched in recent past. I know with past experience, hyphenated domains usually take longer to index, as they are used by spammers more frequently and can take longer to get out of the supplementary index. Our company site has over 90 million viewers / year, so our brand is well established and traffic isn't an issue. This is for a corporate level project and I didn't have the answer! Will this work? anyone have any experience testing this. Any thoughts will help! Thanks, Rob

Duplicate Content issue
I have been asked to review an old website to an identify opportunities for increasing search engine traffic. Whilst reviewing the site I came across a strange loop. On each page there is a link to printer friendly version: http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes That page also has a link to a printer friendly version http://www.websitename.co.uk/index.php?pageid=7&printfriendly=yes&printfriendly=yes and so on and so on....... Some of these pages are being included in Google's index. I appreciate that this can't be a good thing, however, I am not 100% sure as to the extent to which it is a bad thing and the priority that should be given to getting it sorted. Just wandering what views people have on the issues this may cause?
