Do Search Engine Spiders Read Commented Out Content?
Is commented out content detrimental?
-
If you include any links in your comments, Google may crawl them, although they won't pass any link juice. Google is pretty aggressive above spidering any links they find, including unlinked URLs on a page and URLs in javascript, so I wouldn't be surprised if they crawled links in comments as well.

I've never seen Google (or other engines) pay any attention to HTML comments. In fact, I've seen strong evidence that they are completely ignored. It only makes sense. People stick all kinds of things in comments for a wide variety of purposes. I can't imagine why a search engine would do anything else. And as far as Panda is concerned, Panda is aimed at the user's experience and since HTML comments are invisible to users, there's no reason they should have any effect.

Duplicate content issues - page content and store URLs
Hi, I'm experiencing some heavy duplicate content Crawl errors on Moz with www.redrockdecals.com and therefore I really need some help. It brings up different connections between products and I'm having a hard time figuring out what it means. It is listing the same products as duplicate content but they have different URL endings. For example:http://www.redrockdecals.com/car-graphics/chevrolet-silverado?___store=nl&___from_store=us

http://www.redrockdecals.com/car-graphics/chevrolet-silverado?___store=d&___from_store=us It seems like Moz considers the copy-pasted parts in the Full Description (scrolled a bit down on product pages) as Duplicate Content. For example the general text found on this page: http://www.redrockdecals.com/caution-tow-limited-turning-radius-decal Or this page: http://www.redrockdecals.com/if-you-don-t-succeed-first-time-then-skydiving-isn-t-for-you-bumper-sticker I am planning to write new and unique descriptions for all products but what do you suggest - should I either remove the long same descriptions or just shorten them perhaps so they don't outweigh the short but unique descriptions above? I've heard search engines understand that some parts of the page can be same on other pages but I wonder if in my case this has gone too deep... Thanks so much!0 -

Does Google Bias Against Homepages for Search Queries that are a Question?
If you are trying to rank for a keyword phrase that is a question (e.g. how to ___) does it matter if your page is the home page of your site or an article on your site? I suspect that Google would treat question search queries differently and would show preference for articles over a home page in most cases. An article would be more likely to satisfy the searcher by providing the answer to their question, whereas the home page usually doesn't provide specific answers. I looked at one keyword phrase that is a question and only 1 of the first 20 results was a home page. Any thoughts or experience with this?

Software/tool for Content Inventory
Is there any tool out there which can crawl a section of a website (or whole website) and gives a list of urls by subsections? I have tried PowerMapper but it only gives visual map, not a list. Thanks!

Article on site and distribution, is it duplicate content?
I was always taught to place all original articles on site, let them get indexed by Google, then put out for distribution through various press release outlets. With the latest penguin update, how does this practice work out concerning duplicate content? In theory, I wrote the article so I should get credit for it on my site first, then push through various distribution outlets to get it out to my targeted audience in my niche field. Typing out loud I would tend to think if the article is on my site first then I would get credit and any others following would be hit by duplicate content if in fact google considered it a dupe violation. Any input on this? Am I on track or am I heading for a train wreck.

Duplicate content issue in SEOmoz campaign.
Hi, We are running a campaign for a website in SEOmoz. We get a dup content issue warning: http://www.oursite.com and http://www.oursite.com/ are being seen as 2 different urls. Only difference among 2 urls is the trailing slash at the end of the second url. Why is this happening? I was aware of www vs non www but never heard of an issue related to the slash. Thanks for your help!

Google indexes alll our internetal searches: search box is brand - clothes types - size type - and for each page it creates a page that which creates duplicate page title and unnecessary content. Should I do a nofollow on the advance search or a no index. Many thanks for the info. Sonja
