Best practice for duplicate website content: same root domain name but different extension
-
Hi there
I have a new client who has two websites:
http://www.bayofislandsteambuilding.co.nz
http://www.bayofislandsteambuilding.org.nzThey are the same in every regard apart from the domain extension (.co.nz & .org.nz) which is likely to be causing them issues with Google ranking given the huge amount of duplicate content.
What is the best practice approach to fixing this? Normally, if I was starting from scratch, I would set one of the extensions as an alias which redirects to the main domain.
Thanks in advance.

Two URLs containing the same content will be considered as duplicated content, do the domain level redirection so that every URL should redirect to the home page of the preferred domain.

Hi - thanks for the response.
Do I still need to set up 301 redirects for every page or can I do it server-side for the entire domain? And is this approach better than using the rel=”canonical” link element in the http header tags?
Thanks

301 Redirect one to the other. That's it that's all.

Will I be flagged for duplicate content by Google?
Hi Moz community, Had a question regarding duplicate content that I can't seem to find the answer to on Google. My agency is working on a large number of franchisee websites (over 40) for one client, a print franchise, that wants a refresh of new copy and SEO. Each print shop has their own 'microsite', though all services and products are the same, the only difference being the location. Each microsite has its own unique domain. To avoid writing the same content over and over in 40+ variations, would all the websites be flagged by Google for duplicate content if we were to use the same base copy, with the only changes being to the store locations (i.e. where we mention Toronto print shop on one site may change to Kelowna print shop on another)? Since the print franchise owns all the domains, I'm wondering if that would be a problem since the sites aren't really competing with one another. Any input would be greatly appreciated. Thanks again!

SEM Rush & Duplicate content
Hi SEMRush is flagging these pages as having duplicate content, but we have rel = next etc implemented: https://www.key.co.uk/en/key/brand/bott https://www.key.co.uk/en/key/brand/bott?page=2 Or is it being flagged as they're just really similar pages?

What is best practice for "Sorting" URLs to prevent indexing and for best link juice ?
We are now introducing 5 links in all our category pages for different sorting options of category listings.
Intermediate & Advanced SEO | | lcourse
The site has about 100.000 pages and with this change the number of URLs may go up to over 350.000 pages.
Until now google is indexing well our site but I would like to prevent the "sorting URLS" leading to less complete crawling of our core pages, especially since we are planning further huge expansion of pages soon. Apart from blocking the paramter in the search console (which did not really work well for me in the past to prevent indexing) what do you suggest to minimize indexing of these URLs also taking into consideration link juice optimization? On a technical level the sorting is implemented in a way that the whole page is reloaded, for which may be better options as well.0 -
Removing duplicate content
Due to URL changes and parameters on our ecommerce sites, we have a massive amount of duplicate pages indexed by google, sometimes up to 5 duplicate pages with different URLs. 1. We've instituted canonical tags site wide. 2. We are using the parameters function in Webmaster Tools. 3. We are using 301 redirects on all of the obsolete URLs 4. I have had many of the pages fetched so that Google can see and index the 301s and canonicals. 5. I created HTML sitemaps with the duplicate URLs, and had Google fetch and index the sitemap so that the dupes would get crawled and deindexed. None of these seems to be terribly effective. Google is indexing pages with parameters in spite of the parameter (clicksource) being called out in GWT. Pages with obsolete URLs are indexed in spite of them having 301 redirects. Google also appears to be ignoring many of our canonical tags as well, despite the pages being identical. Any ideas on how to clean up the mess?

How to deal with competition with a similar domain name as my client website?
How can I deal with other websites that have a keyword domain name similar to my client website? I get a few domains similar to my client domain name just to avoid the same issue, but there are a few others ranking for the same keywords and I don't want posible customers get confused with a similar domain name. I have social media (Facebook, Twitter, Linked in and etc), but they are not ranking on the first page. This is the situation: www.domain.com that would be my client's domain. And the competition: www.bestdomain.com www.thedomain.com www.domaincomapany.com And a few more. At this time my client is ranking #1 position, but all the others ar 1 or 2 positions bellow.

Duplicate content on ecommerce sites
I just want to confirm something about duplicate content. On an eCommerce site, if the meta-titles, meta-descriptions and product descriptions are all unique, yet a big chunk at the bottom (featuring "why buy with us" etc) is copied across all product pages, would each page be penalised, or not indexed, for duplicate content? Does the whole page need to be a duplicate to be worried about this, or would this large chunk of text, bigger than the product description, have an effect on the page. If this would be a problem, what are some ways around it? Because the content is quite powerful, and is relavent to all products... Cheers,

There's a website I'm working with that has a .php extension. All the pages do. What's the best practice to remove the .php extension across all pages?
Client wishes to drop the .php extension on all their pages (they've got around 2k pages). I assured them that wasn't necessary. However, in the event that I do end up doing this what's the best practices way (and easiest way) to do this? This is also a WordPress site. Thanks.
