<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?

Staging & Development areas should be not indexable (i.e. no followed/no index in meta robots etc)
Hi I take it if theres a staging or development area on a subdomain for a site, who's content is hence usually duplicate then this should not be indexable i.e. (no-indexed & nofollowed in metarobots) ? In order to prevent dupe content probs as well as non project related people seeing work in progress or finding accidentally in search engine listings ? Also if theres no such info in meta robots is there any other way it may have been made non-indexable, or at least dupe content prob removed by canonicalising the page to the equivalent page on the live site ? In the case in question i am finding it listed in serps when i search for the staging/dev area url, so i presume this needs urgent attention ? Cheers Dan

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?

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!

Redirecting blog.<mydomain>.com to www.<mydomain>.com\blog</mydomain></mydomain>
This is more of a technical question than pure SEO per se, but I am guessing that some folks here may have covered this and so I would appreciate any questions. I am moving from a WordPress.com-based blog (hosted on WordPress) to a WordPress installation on my own server (as suggested by folks in another thread here). As part of this I want to move from the format blog.<mydomain>.com to www.mydomain.com\blog. I have installed WordPress on my server and have imported posts from the hosted site to my own server. How should I manage the transition from first format to the second? I have a bunch of links on Facebook, etc that refer to URLs of the blog..com format so it's important that I redirect.</mydomain> I am running DotNetNuke/WordPress on my own IIS/ASP.Net servers. Thanks. Mark

Google Off/On Tags
I came across this article about telling google not to crawl a portion of a webpage, but I never hear anyone in the SEO community talk about them. http://perishablepress.com/press/2009/08/23/tell-google-to-not-index-certain-parts-of-your-page/ Does anyone use these and find them to be effective? If not, how do you suggest noindexing/canonicalizing a portion of a page to avoid duplicate content that shows up on multiple pages?
