SEOMoz Crawler vs Googlebot Question
-
I read somewhere that SEOMoz’s crawler marks a page in its Crawl Diagnostics as duplicate content if it doesn’t have more than 5% unique content.(I can’t find that statistic anywhere on SEOMoz to confirm though).
We are an eCommerce site, so many of our pages share the same sidebar, header, and footer links. The pages flagged by SEOMoz as duplicates have these same links, but they have unique URLs and category names. Because they’re not actual duplicates of each other, canonical tags aren’t the answer. Also because inventory might automatically come back in stock, we can’t use 301 redirects on these “duplicate” pages.
It seems like it’s the sidebar, header, and footer links that are what’s causing these pages to be flagged as duplicates. Does the SEOMoz crawler mimic the way Googlebot works? Also, is Googlebot smart enough not to count the sidebar and header/footer links when looking for duplicate content?

Google bot definitely won't ding you for duplicate content based upon you sidebar, header, and footer links. I've managed several ecommerce sites and have never had this problem.
However, it may still ding you for duplicate content if you have several matching pages with you main column being the same.

Hide messenger for crawlers
At Magnet.me we are using Intercom to communicate with our users. This means that we are actively adding javascript code which will load the Intercom javascript on each page, and render the button afterwards. However, this button has no value for crawlers, and slows the page down as the javascript is big and fairly slow. Therefore I considered to ship some code which disables this button, such that performance would improve. To give a ball pack estimate, the buttons javascript is around 3x bigger than the actual entire react application... Unfortunately this would result in giving users and crawlers slightly different content on the page. I'm unsure about the possible SEO impact: Would Google mark the page as faster due to less resources to load? Or would it penalize the page for showing slightly different content to users and search engines?

Question on noscript tags and indexing
If I have a <noscript>tag on every page of my website with the same sentence over and over saying something to the effect of "Sorry our site uses Javascript, please enable javascript for the full site experience.", Webmaster Tools will tell me that one of the most common words on my site is "Javascript".</p> <p>Is this something to be concerned about from an SEO perspective? My site is obviously not about Javascript and I don't want to dilute my page's topic or authority by repeating words that are not relevant to the topic of my site.</p> <p>Thanks!</p></noscript>

Redirect Impact - Moving From SEOmoz to Moz
Hey Guys, This has been on my mind ever since the big announcement, so today I did some searching around for some posts/talk about what the impact of their full site redirect has been for them and didn't find anything. Have they posted on this or are there any threads that I'm missing out on? I'd love to hear more about what the impact has been or any general thoughts/insights people may have. Thanks!

Question about construction of our sitemap URL in robots.txt file
Hi all, This is a Webmaster/SEO question. This is the sitemap URL currently in our robots.txt file: http://www.ccisolutions.com/sitemap.xml As you can see it leads to a page with two URLs on it. Is this a problem? Wouldn't it be better to list both of those XML files as separate line items in the robots.txt file? Thanks! Dana

2 questions about linkbuilding
1. Are these types of sites bad to submit a link to? http://www.mompack.com/mom2mom/ 2. If I submit my product for another blog to review (in turn they write a post for me with links to my website), is this GOOD? Look forward to hearing back from you, thanks

Question about Robot.txt
I just started my own e-commerce website and I hosted it to one of the popular e-commerce platform Pinnacle Cart. It has a lot of functions like, page sorting, mobile website, etc. After adjusting the URL parameters in Google webmaster last 3 weeks ago, I still get the same duplicate errors on meta titles and descriptions based from Google Crawl and SEOMOZ crawl. I am not sure if I made a mistake of choosing pinnacle cart because it is not that flexible in terms of editing the core website pages. There is now way to adjust the canonical, to insert robot.txt on every pages etc. however it has a function to submit just one page of robot.txt. and edit the .htcaccess. The website pages is in PHP format. For example this URL: www.mycompany.com has a duplicate title and description with www.mycompany.com/site-map.html (there is no way of editing the title and description of my sitemap) Another error is www.mycompany.com has a duplicate title and description with http://www.mycompany.com/brands?url=brands Is it possible to exclude those website with "url=" and my "sitemap.html" in the robot.txt? or the URL parameters from Google is enough and it just takes a lot of time. Can somebody help me on the format of Robot.txt. Please? thanks

Robots.txt questions...
All, My site is rather complicated, but I will try to break down my question as simply as possible. I have a robots.txt document in the root level of my site to disallow robot access to /_system/, my CMS. This looks like this: # /robots.txt file for http://webcrawler.com/

# mail webmaster@webcrawler.com for constructive criticism **User-agent: ***
Disallow: /_system/ I have another robots.txt file in another level down, which is my holiday database - www.mysite.com/holiday-database/ - this is to disallow access to /holiday-database/ControlPanel/, my database CMS. This looks like this: **User-agent: ***
Disallow: /ControlPanel/ Am I correct in thinking that this file must also be in the root level, and not in the /holiday-database/ level? If so, should my new robots.txt file look like this: # /robots.txt file for http://webcrawler.com/
# mail webmaster@webcrawler.com for constructive criticism **User-agent: ***
Disallow: /_system/
Disallow: /holiday-database/ControlPanel/ Or, like this: # /robots.txt file for http://webcrawler.com/
# mail webmaster@webcrawler.com for constructive criticism **User-agent: ***
Disallow: /_system/
Disallow: /ControlPanel/ Thanks in advance. Matt0
