Blog posts, blog archives and duplication
-
Just reviewed a blog integrated with my website, and have noticed duplicate content - the blog homepage includes blogpost summaries (not a major issue as now set up so only put in opening paragraphy then anchor text to full blog post).
Then that's a full blog blog post if you click for more - then that's carbon copied over in the archive. So one near exact duplicate.
Is this something worth taking action on with nocrawl tags, etc., on archive duplicates of blog posts, or shouldn't I be to hung-up on this? I'm a scientist by training, so tend to go further and further once I get going...

Thanks Marcus - that's very useful. I am using Wordpress as it happens
Off to do some reading... -
Hey Luke
As a general rule of thumb, blogs will offer up a fair bit of duplication through tags, categories and archives so it can be worth not indexing those pages. For the posts themselves, you should have the option to create a unique snippet rather than using the first couple of blog paragraphs if you wanted to do that (best practice) but the duplication of the blog posts should be handled by the canonical tag so there is only one true instance of the article on the site.
You don't mention which blog package you are using but for WordPress, the yoast SEO plugin will help you easily deal with most common issues.

The plugin does not do this all on installation and requires some simple configuration to fit your circumstances but the following page walks you through the configuration of the plugin so you can make a call on what to index, noindex, etc.
http://yoast.com/articles/wordpress-seo/
What if you are not using WordPress? Well, I would still read the above article. It deals with issues common to most blog platforms and covers technical optimisation, template tweaks, site structure, conversions and most importantly for you (section 3 I think) covers duplication created by the blog, pagination etc.
Well worth a read if only to get you thinking in the right direction and if you are using WordPress, then the plugin and that tutorial will put most of your problems, if not all to bed.
Hope it helps!
Marcus

SEO issues with masking blog domain?
We have a client who would like to move their Wordpress blog into a different server from their main site's server for security reasons. However, the blog is almost 10 years old with good traffic and rankings and we'd rather not have them change the domain. The developer has come back with a URL "masking" rule in .htaccess that will display the contents of the blog placed in the new server under a subdomain but still show the blog's original URL. If we block the new subdomain from indexing to avoid duplicate content - are there any SEO implications for doing this? Will Google see it as a deceptive practice and tank the blog's rankings? Any advice is greatly appreciated.

Blog tags are creating excessive duplicate content...should we use rel canonicals or 301 redirects?
We are having an issue with our cilent's blog creating excessive duplicate content via blog tags. The duplicate webpages from tags offer absolutely no value (we can't even see the tag). Should we just 301 redirect the tagged page or use a rel canonical?

Redirecting external blog to main website blog - two questions I'm struggling with
Hiya Mozzers - I have a blog separate from main website which is duplicating the blog on the main website. This separate blog is duplicating the main website blog, so it needs to be closed down and redirected. There are some 200 pages of separate blog (identified via Screaming Frog). So I am suggesting the blog pages should be 301 redirected from the separate blog to the equivalent blog pages on the main website. Q1) Should the root domain of the separate blog be 301 redirected to the main www.mainwebsite.com/blog page, or to the root domain of the main website? Q2) Should the blog pages, which lack equivalent content on the main website, be 301 redirected to the main www.mainwebsite.com/blog page, or to the root domain of the main website? Thanks for your help on this one, Luke

Duplicate Content Question
Currently, we manage a site that generates content from a database based on user search criteria such as location or type of business. ..Although we currently rank well -- we created the website based on providing value to the visitor with options for viewing the content - we are concerned about duplicate content issues and if they would apply. For example, the listing that is pulled up for the user upon one search could have the same content as another search but in a different order. Similar to hotels who offer room booking by room type or by rate. Would this dynamically generated content count as duplicate content? The site has done well, but don't want to risk a any future Google penalties caused by duplicate content. Thanks for your help!

Duplicate Content On A Subdomain
Hi, We have a client who is currently close to completing a site specifically aimed at the UK market (they're doing this in-house so we've had no say in how it will work). The site will almost be a duplicate (in terms of content, targeted keywords etc.) of a section of the main site (that sits on the root domain) - the main site is targeted toward the US. The only difference will be certain spellings and currency type. If this new UK site were to sit on a sub domain of the main site, which is a .com, will this cause duplicate content issues? I know that there wouldn't be an issue if the new site were to be on a separate .co.uk domain (according to Matt Cutts), but it looks like the client wants it to be on a sub domain. Any help/advice would be greatly appreciated.

BEING PROACTIVE ABOUT CONTENT DUPLICATION...
So we all know that duplicate content is bad for SEO. I was just thinking... Whenever I post new content to a blog, website page etc...there should be something I should be able to do to tell Google (in fact all search engines) that I just created and posted this content to the web... that I am the original source .... so if anyone else copies it they get penalised and not me... Would appreciate your answers... 🙂 regards,

Should I do something about this duplicate content? If so, what?
On our real estate site we have our office listings displayed. The listings are generated from a scraping script that I wrote. As such, all of our listings have the exact same description snippet as every other agent in our office. The rest of the page consists of site-wide sidebars and a contact form. The title of the page is the address of the house and so is the H1 tag. Manually changing the descriptions is not an option. Do you think it would help to have some randomly generated stuff on the page such as "similar listings"? Any other ideas? Thanks!
