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?
-
I usually do one of these:
-
put the duplicate content in an iframe (ugly and not flexible). I use this for static content like ad spaces
-
load the content async with Javascript. All googlebot will index is an empty div. The user will see the content loaded with JS after the page loaded. In most cases there is no noticeable difference in how the page renders.Very easy to do with Jquery. My favorite solution.

Thanks for clarifying!
Do you have any suggestions on how I can avoid duplicate content that is appearing on multiple pages without noindexing the whole page (there is original content at the top, duplicate at the bottom)?

<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.

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/

Google is indexing my directories
I'm sure this has been asked before, but I was looking at all of Google's results for my site and I found dozens of results for directories such as: Index of /scouting/blog/wp-includes/js/swfupload/plugins Obviously I don't want those indexed. How do I prevent Google from indexing those? Also, it only seems to be doing it with Wordpress, not any of the directories on my main site. (We have a wordpress blog, which is only a portion of the site)

How do I fix the h1 tag?
No More Than One H1 Tag Easy fix <dl> <dt>Number of H1s</dt> <dd>2</dd> <dt>Explanation</dt> <dd>Best practices for both SEO and accessibility require only a single H1 tag. The H1 is meant to be the page's headline, and thus, multiple H1s are confusing. Consider employing H2, H3 or CSS styles to achieve the same results with text visualization.</dd> <dt>Recommendation</dt> <dd>Remove multiple instances of the H1 tag, so that only one exists on the page.</dd> <dd>I get this error yet it does not tell me how to fix it. I'm not even sure what the H1 tag is?

UK website ranking higher in Google.com than Google.co.uk
Hi, I have a UK website which was formerly ranked 1<sup>st</sup> in Google.co.uk and .com for my keyword phrase and has recently slipped to 6<sup>th</sup> in .co.uk but is higher in position 4 in Google.com. I have conducted a little research and can’t say for certain but I wonder if it is possible that too many of my backlinks are US based and therefore Google thinks my website is also US based. Checked Google WmT and we the geo-targeted to the UK. Our server is also UK based. Does anyone have an opinion on this? Thanks
