Welcome to the Q&A Forum

I'd honestly leave it alone. I've never seen a preventive canonical (even if unnecessary) cause problems. As you expand the site, it could help prevent future problems, implemented correctly. In terms of SEOmoz, I wouldn't worry about the notice - it's just a notice, which we put even below a warning. We're evaluating how to assess canonical for future versions of the software, because it is confusing to people.

Just curious - where do you see the JS redirects? I'm seeing server-side redirects, but the interesting thing is that the return a 200 (not a 301 or 302), which could suggest they pass link-juice. My gut sense is that Miriam's right - they probably mask direct link-juice but are still very valuable as a citation, especially for local search.

I think John is spot on, but just wanted to add a couple of things: (1) The 100-link "rule" is really just a guideline. Adding nofollow wouldn't impact how we count or, likely, how Google counts. Nofollows still dilute link-juice. (2) If the footer links duplicate main-navigation links, then they may not be counted at all. Google discounts any additional links to Page B from Page A, and will more or less ignore them.

You're welcome. As long as you keep this interlinking between those blogs natural (and in order to benefit your visitors), you could do this, yes.

Thank you! I'm glad someone finally answered this! I really need to get going on it. I think that is what I'm going to do--make a top-level page for the main categories and then only have navigation to the sub-categories on the top top-level page for each category. It seems like the best solutions for both humans and bots.

Could you please check this other question?? http://www.seomoz.org/q/keyword-canabalisation-and-my-solution

Changing them will definitely still matter! Google will periodically visit your (and every other) website to see if content has changed, or new content can be found. Once you make sure the content isn't duplicate anymore, Google will discover this and might (or might not) act upon does.

Google will see the content as plain text, check for example seobrowser.com. However, there is a chance that Google is parsing the CSS to find out that this particular content is hidden, and therefore devalues it. I don't recall ever reading about this, but it would make some sense because many visitors won't see the text.

Have you removed the malicious code? If so, is THFCTalk registered with Google Webmaster Tools? If the code has been removed you can file a reconsideration request in there. If you haven't, you can also see which pages are affected. All websites should be registered with Webmaster Tools (and the Bing equivalent)! You can set up alerts so Google e-mail you about any major problems they find. Here are some links that should help you, whatever stage you're at: http://25yearsofprogramming.com/blog/20071223.htm http://googlewebmastercentral.blogspot.com/2008/04/my-sites-been-hacked-now-what.html P.S. I hope Harry stays and Spurs win the title (from a Stoke fan)!

Hi Sebastian, Having duplicate content is quite a problem for you. You have two pages with the same content and different inbound links profile, confusing the search engines with it. Resolving this issue (with a canonical or a 301 redirect) will point out the page you are targeting from the two and make it easier to compete with. 301 or a canonical will also provide the link juice flow from one of the pages to the other one. 1. Do you have an idea why the with www version is not indexed?  2. How long does Google usually take to change the version in the index? 3. Do I risk my site to be thrown out of the index for some days untill the change is made? 1. If you would be a search engine and see duplicate content from the same provider would you index both? 2. I would say that after resolving this issue, create a Google Webmaster Tools account, submit your sitemap and you should see some change in a few days. 3. After Google will index your canonicals you will have the non-www deindexed and the www version indexed. Now probably you will see some kind of fluctuation in this process, but after done you should see a comeback soon. Google won't punish you after you make these changes to help them. Quite logical, right?! I hope it was helpful, Istvan

Ok - I will ask something else which might help (and which I might understand). From reading around, I understand that search engines will index pages with ?category=foo&subcategory=fee on the end. Can anyone confirm this, as if this is true it will make my life a lot easier! Thanks

Hey Ardi, When we first started with Seomoz we asked ourself the exact same questions. After contacting the staff at Seomoz we know understand it quite a bit better. The way it works is that the Seomoz crawler crawls the web for 2-3 weeks. After this, it has to create metrics (such as PA/DA) out of all the data, which usually takes up the rest of the month. Unfortunately, as this is quite a huge job it takes around 4 weeks or longer. The next update was supposed to be this week, but is now being set back until the 29th. Open Site Explorer isn't the only tool you could use, one other one which was mentioned by Seomoz in the past is the Majestic Site Explorer one, https://www.majesticseo.com/reports/site-explorer . I still prefer OSE by a margin, but Majestic update their index at a faster rate. Even if some of your link aren't picked up after the update, it could be because the location of the link is on a website that isn't to popular. If that is the case, you will have to wait until further index updates, in order for it to appear.

Could be a few things. 1. The scoring is different between the two tools. I looked and couldn't find any specifics on their API's, but they could place weight on different factors. In the second tool, it looks like the first tab is from Google's page speed tool since the second is Yahoo's. The scores between the two were different. 2. The location where the test is done can impact speed. The closer the testing server is to the server that the website is hosted on, the faster the load time will be. 3. Could be a difference in caching? If your site has flushed its cache, the load time can be slower while the server re-caches things, then it will be faster later. This usually isn't the case, but I've seen it happen. As for your second question, I'm not sure of a definite way. If your caching is working properly, it should just happen... Hope that helps.

Thanks a lot. I'll try and make the modifications and post the results when I have them.

Thanks for posting the video that was exactly what I needed 

Using Google and I'm entering the exact URL in the search.  No results are found.  I know this means it's not indexed, but why does the SEOmoz crawler pick it up?

Kenji, you'd better spend your time on improving your own website and asking yourself a question: "What else I can do for my visitors, how can I improve their impression of my site?", instead of chasing your competitors. Just my 2 cents. That would be a better time investment.
