<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?

Setting title tag with javascript/jquery
Hi there, I'm looking for some advice. I've recently implemented a few jQuery functions which gets specific content from the page and then sets the title and description. See working example here. It seems to work fine but my question I have is whether Google bots can read it and whether it might actually hinder my SEO efforts? Any advice would be really appreciated! Peter

Isnt it better to have headlines in H1 and H2 tags instead of p tags?
I am working with a simple site http://http://lightsigns.com/Uniko_Manufacturing_Limited.html They seek more SEO traffic. However, the two big headlines that read "Wholesale Supply to the Sign and Display Industries" which is on line 241 and 242 of the source code, its in a p tag, i.e. <p <span class="webkit-html-tag">style</p <span>="padding-top: 0pt; " class="paragraph_style_1">Wholesale Supply to the and <p <span class="webkit-html-tag">style</p <span>="padding-bottom: 0pt; " class="paragraph_style_1">Sign and Display Industries Likewise, the product titles are in p tags, also. For example, on the Slide-in Light Box product page, http://lightsigns.com/Slide_In_light_box.html , I have done keyword research and no one is using the words slide in light box.Plus, it is also a p tag, ie. line 43 reads style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style">Slide-in Light Box If I suggest that they make an H2 tag with SEO-optimized keywords such as Display Light Box - Slide-In LIght Box, would this indeed help SEO? In summary, is it correct to say that H1 and H2 tags are stronger signals to the search bots of what the page is about?

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?

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?
