Is it ok to use both 301 redirect and rel="canonical' at the same time?
-
Hi everyone,
I'm sorry if this has been asked before. I just wasn't able to find a response in previous questions.
To fix the problems in our website regarding duplication I have the possibility to set up 301's and, at the same time, modify our CMS so that it automatically sets a rel="canonical" tag for every page that is generated.
Would it be a problem to have both methods set up?
Is it a problem to have a on a page that is redirecting to another one?
Is it advisable to have a rel="canonical" tag on every single page?
Thanks for reading!

Yeah, I'm with Alan - what works in theory and what works in practice can really vary with the site - if you do both at once and something goes wrong, you won't know which tactic was the problem. Even if it goes right, you won't know which one worked.
Keep in mind, too, that 301s and canonicals have different purposes. They may act similarly for search, in some cases, but they're very different for site visitors. A 301-redirect will actually take the visitor to a new page. A canonical will let the duplicate URL be visited but remove it from search results. In most cases, one is more appropriate to your situation than the other.

Theory: Google is pretty good at figuring things out.
Reality: Google's algorithms, that go through hundreds of changes, tweaks and modifications every year are a soupy mess and their ability to "figure things out" was proven so flawed last year that along with Microsoft and Yahoo, they came up with Schema.org just to address PART of that reality.
Recommendation: Never do anything that could possibly confuse Google if you don't absolutely have to.

Should I redirect a domain we control but which has been labeled 'toxic' or just shut it down?
Hi Mozzers: We recently launched a site for a client which involved bringing in and redirecting content which formerly had been hosted on different domains. One of these domains still existed and we have yet to bring over the content from it. It has also been flagged as a suspicious/toxic backlink source to our new domain. Would I be wise to redirect this old domain or should I just shut it down? None of the pages seem to have particular equity as link sources. Part of me is asking myself 'Why would we redirect a domain deemed toxic, why not just shut it down.' Thanks in advance, dave

Using hreflang="en" instead of hreflang="en-gb"
Hello, I have a question in regard to international SEO and the hreflang meta tag. We are currently a B2B business in the UK. Our major market is England with some exceptions of sales internationally. We are wanting to increase our ranking into other english speaking countries and regions such as Ireland and the Channel Islands. My research has found regional google search engines for Ireland (google.ie), Jersey (google.je) and Guernsey (google.gg). Now, all the regions have English as one their main language and here is my questions. Because I use hreflang=“en-gb” as my site language, am I regional excluding these countries and islands? If I used hreflang=“en” would it include these english speaking regions and possible increase the ranking on these the regional search engines? Thank you,

Should pages with rel="canonical" be put in a sitemap?
I am working on an ecommerce site and I am going to add different views to the category pages. The views will all have different urls so I would like to add the rel="canonical" tag to them. Should I still add these pages to the sitemap?

"noindex, follow" or "robots.txt" for thin content pages
Does anyone have any testing evidence what is better to use for pages with thin content, yet important pages to keep on a website? I am referring to content shared across multiple websites (such as e-commerce, real estate etc). Imagine a website with 300 high quality pages indexed and 5,000 thin product type pages, which are pages that would not generate relevant search traffic. Question goes: Does the interlinking value achieved by "noindex, follow" outweigh the negative of Google having to crawl all those "noindex" pages? With robots.txt one has Google's crawling focus on just the important pages that are indexed and that may give ranking a boost. Any experiments with insight to this would be great. I do get the story about "make the pages unique", "get customer reviews and comments" etc....but the above question is the important question here.

After reading of Google's so called "over-optimization" penalty, is there a penalty for changing title tags too frequently?
In other words, does title tag change frequency hurt SEO ? After changing my title tags, I have noticed a steep decline in impressions, but an increase in CTR and rankings. I'd like to once again change the title tags to try and regain impressions. Is there any penalty for changing title tags too often? From SEO forums online, there seems to be a bit of confusion on this subject...

Posing QU's on Google Variables "aclk", "gclid" "cd", "/aclk" "/search", "/url" etc
I've been doing a bit of stats research prompted by read the recent ranking blog http://www.seomoz.org/blog/gettings-rankings-into-ga-using-custom-variables There are a few things that have come up in my research that I'd like to clear up. The below analysis has been done on my "conversions". 1/. What does "/aclk" mean in the Referrer URL? I have noticed a strong correlation between this and "gclid" in the landing page variable. Does it mean "ad click" ?? Although they seem to "closely" correlate they don't exactly, so when I have /aclk in the referrer Url MOSTLY I have gclid in the landing page URL. BUT not always, and the same applies vice versa. It's pretty vital that I know what is the best way to monitor adwords PPC, so what is the best variable to go on? - Currently I am using "gclid", but I have about 25% extra referral URL's with /aclk in that dont have "gclid" in - so am I underestimating my number of PPC conversions? 2/. The use of the variable "cd" is great, but it is not always present. I have noticed that 99% of my google "Referrer URL's" either start with:

301 redirect from .html to non .html?
Previously our site was using this as our URL structure: www.site.com/page.html. A few months ago we updated our URL structure to this: www.site.com/page & we're not using the .html. I've read over this guide & don't see anywhere that discusses this: http://www.seomoz.org/learn-seo/redirection. I've currently got a programmer looking into, but am always a bit weary with their workarounds, as I'd previously had them cause more problems then fix it. Here is the solution he is looking to do: The way that I am doing the redirect is fine. The problem is of where to put the code. The issue is that the files are .html files that need to be redirected to the same url with out a .html on them. I can see if I can add that to the 404 redirect page if there is one inside of there and see if that does the trick. That way if there is no page that exists without the .html then it will still be a 404 page. However if it is there then it will work as normal. I will see what I can find and get back. Any help would be greatly appreciated. Thanks, BJ
