Reducing Duplicate Content on WordPress Blogs

Last Monday we missed the video post, but this week it is here. The topic of the day is duplicate content, its definition and how you can reduce its occurrence on WordPress blogs.

I tried to use the .wmv format to reduce the size of the file, but the quality suffered a bit. Next week we will be back with .avi.

Here is a quick summary:

Duplicate content refers to two or more web pages that have the same, or almost the same, content.
Those two or more pages can be located on different or on the same website, so you can have duplicate content inside your blog also.
Most of the times it is a good idea to avoid duplicate content since search engines might penalize it.
WordPress themes (this is fault of the designers and not of the WordPress software itself) tend to come with a lot of duplicate content out of the box.
Apart from the homepage, it is a good idea to check your categories and archive pages to see whether full posts are being displayed there or not
Remember that your goal is to make sure that your posts or articles can accessed in full from only one location inside your site.

The plugin that I mentioned is the homepage excerpts one. Finally, if you can’t see the video player, here is the YouTube link: Daily Blog Tips - Duplicate Content.

There is a lot of different information about duplicate content out there, so it can get confusing.

I never thought about the duplicate content automatically generated by Wordpress blogs before… so this was very helpful and I’m going to check my blogs today and make any necessary changes.

Thanks.

Good video Daniel.

Putting - NoIndex, Follow - on archived pages also helps. I did the same on category pages too. But, some blogs get good traffic on categorized pages, noindexing is not recommended in those cases.

Jill Whalen wrote a guest post on TopRankBlog today (@ http://www.toprankblog.com/200.....and-scams/)

What do you think about that she wrote that “Duplicate content will get your site penalized” under the myths section?

I always thought duplicate content was a no-no…
Daniel Scocco on June 23rd, 2008 4:35 pm

@Adam, I am not sure. If Google takes the time to write a specific page about something, I will sure take the time to read and follow what they say there .

Duplicate content…turns people off fast
Rick on June 23rd, 2008 8:28 pm

Do you mean we should use the default excerpt or create an excerpt with each post? If it’s the former than why not use the_content() with the tag instead? One problem with the default excerpt is that it takes the first 55 words but excludes images. (In my case the images are LaTex formulas that are essential for the default excerpt to make sense.)
Rick on June 23rd, 2008 8:31 pm

correction: prior comment should have said “with the MORE tag instead?”
Kaspars on June 23rd, 2008 8:39 pm

There is no need to show only excerpts (which are also in fact duplicate content, but only a paragraph or two long) on archive pages, if you use the noindex, follow meta tag in those pages.

Put this PHP fragment in your header.php file just after the title tag:

<?php if (is_archive()) : ?><meta name="robots" content="noindex,follow" /><?php endif; ?>

It will tell the search engines to follow the links, but to not save them in the search index. is_archive() is a WordPress function that returns true only if an archive page (by date, category or tag) is being viewed.

Yes, the quality of the video is a little bad, but enough. Thank you for the nice video
Melvin on June 24th, 2008 5:32 am

thanks for the youtube link… i haven’t heard of home excerpts!
Daniel Scocco on June 24th, 2008 8:02 am

@Rick, you have the optional excerpt field also where you can copy and paste the text, pictures or video that you wanted displayed as excerpt on the homepage and other pages.

That is what I use, and the one I think is the the most flexible.
Locjan on June 24th, 2008 8:35 am

so do you have tips to convert a duplicate content to unique content? how about a tool that can change a grammar like transtool

I use full posts on all my pages, but I also use robots.txt file. I guess both ways work
Wayne on June 24th, 2008 5:37 pm

Great post and I have a follow up question you may be able to answer for me. I have a blog that has been active only a couple months. It’s a real estate blog that sits on the website of a television station. I have recently started a new website with a Wordpress blog attached to it. I was hoping to pretty much duplicate what I do on the television-based blog onto the Wordpress blog. Is that a bad idea altogether?

Thanks so much for your help…
Dennis Edell on June 25th, 2008 4:47 am

I use the all-in-one seo plugin…a simple tick box (3 actually) for no index or categories, archives, tag archives.
Daniel Scocco on June 25th, 2008 6:14 pm

@Wayne, I will answer to it on Friday.

I wonder how that affects all those article submission sites? And then people using the same articles the world over for ezines, newsletters, blog feeds, etc?
Taryn Merrick on July 5th, 2008 5:28 pm

Thank you for this. I am planning 2 different blogs for different aspects of my Virtual Assistant business. Thanks to this I will safeguard it against duplicate content…

E’ stata una buona lettura, degli ottimi accorgimenti!
Zath on July 15th, 2008 6:21 pm

I really do think about this quite a lot with regard to my blog - I have all my archive/tag/category pages showing only excerpts, however once or twice a week I syndicate an entire post from another site (which also goes onto other sites too) - do you think this risks harming my overall site rankings? Or just that particular page?

I always try to put my own commentary at the beginning to introduce the syndicated post to try and make it a little more unique - I’d be interested in hearing other people’s thoughts on this one? - an example would be http://www.zath.co.uk/family-g.....-emotions/

Any feedback would be much appreciated on this one. Should I adding these as exclusions on my robots.txt?
Daniel Scocco on July 15th, 2008 6:55 pm

@Kathie, it wont do you any good if you use those articles on your blog. If you plan to do article marketing, therefore, write stuff specifically for that purpose.

@Zath, I think this is not a big issue, and should only hurt the rankings of that particular page.
Kathie Thomas, A Clayton's Secretary on July 15th, 2008 7:43 pm

I wasn’t saying I use the same articles for my blogs but I was trying to point out that people write articles and submit them to article submission sites and those articles are used over and over again. So does this same ruling apply to those or does it only apply to blogs? I write different articles for my blogs but there have been times I’ve revamped an article to submit it for an online publication.
