Was ist Duplicate Content eigentlich?

Duplicate content or DC as the cool kids call it refers to substantial blocks of text that appear in multiple places online.

It’s like having identical twins running around confusing everyone.

Think of it this way: Google’s like a librarian trying to organize a massive library; it gets super frustrated when it finds the same book shelved in ten different places.

It can’t decide which version is “best” leading to ranking issues and potential penalties.

Now not every repeated sentence screams “DC!” For instance quoting someone with proper attribution is fine. Different language versions of the same content are generally okay too unless they’re scattered across unrelated domains. The key is substantial duplication – copying large sections of text without significant alteration is a major no-no. Google’s algorithms are far more sophisticated than they used to be; they easily detect even slightly reworded copy.

Arten von Duplicate Content

We need to talk about the two main types of duplicate content: internal and external.

Internal duplicate content happens when your own website has the same material accessible via different URLs.

This often arises unintentionally; maybe you categorized a blog post in multiple places creating several links that all lead to the same content.

E-commerce sites with their numerous product pages and categories are particularly vulnerable to this.

Imagine this scenario: www.beispielshop.de/kategorie1/produktseite/produkt1 and www.beispielshop.de/produkt1. Both link to the same product page.

To Google this looks suspiciously like duplicate content.

The same goes for URLs with extra parameters like search terms or campaign IDs.

If they all lead to identical content Google will flag it.

External duplicate content occurs when identical content appears on entirely different websites.

This can stem from your own actions (like distributing a press release across multiple sites) or from others (someone blatantly copying your work). Content theft is a nasty business but it’s a reality – your unique content suddenly showing up elsewhere will impact Google’s ability to identify and rank your original.

Duplicate Content finden: Methoden & Werkzeuge

you suspect you have a DC problem.

Where do you even begin? Fear not my friend.

There are several tried and tested methods ranging from simple Google searches to sophisticated software tools.

Manuelles Checken & Google Search Console

For a quick and dirty check you can manually search for unique phrases from your content.

If similar passages pop up on other websites you’ve found a potential external duplicate.

But let’s get real –manual searches are tedious.

Luckily Google provides tools to help.

The Google Search Console (GSC) is your best friend here.

It directly shows you pages Google considers duplicates.

Navigate to “Coverage” under the “Index” section.

You’ll find a summary of indexed and excluded pages and why.

Pay close attention to the pages marked “excluded.” GSC can give you a good idea of what pages Google views as duplicates.

Once you’ve identified potential duplicate pages using the GSC the next step is to use the URL inspection tool to drill down and discover the root cause.

Screaming Frog & Andere SEO-Tools

For more in-depth analysis dedicated SEO tools are invaluable.

Screaming Frog for example is a powerful crawler that can identify duplicate content.

The free version allows you to crawl up to 500 pages.

It analyzes page titles meta descriptions and URLs for duplicates.

Other similar tools such as SEMrush or Ahrefs offer similar functions but may require a subscription fee.

Choosing which tool best suits your workflow is important.

Siteliner für internen Duplicate Content

Siteliner’s a nifty tool for quickly assessing internal duplicate content.

It scans your entire website and presents a visual representation of any duplication highlighting potential problems in an easy-to-understand way.

It’s great for getting a quick overview but might not catch everything.

Copyscape für externen Duplicate Content

For finding external duplicate content Copyscape is your go-to tool.

Just paste a URL and it will search for matches across the web.

It highlights any copied content directly on the page making it simple to pinpoint plagiarized material.

It’s a superb resource for detecting whether your content has been stolen.

Duplicate Content beseitigen und vermeiden: Strategien & Techniken

Now comes the good part – fixing and preventing the dreaded DC.

This involves a combination of technical adjustments and content strategies.

Der Canonical Tag

The canonical tag is your secret weapon.

This HTML tag tells search engines which version of a page is the “original” and should be prioritized in search results.

If you have multiple versions of the same content – say a printer-friendly version and a regular version – the canonical tag makes it crystal clear which one is the main version.

301-Weiterleitungen

301 redirects are another effective solution.

They permanently redirect one URL to another consolidating the link authority.

This is useful for merging duplicate pages.

This is particularly helpful for dealing with “www” and “non-www” variations of your site.

But use caution – redirects might not be the best choice if you rely on multiple URL versions for specific purposes (e.g.

tracking).

Robots Meta Tags

Use robots meta tags to prevent search engines from indexing certain pages.

This can be helpful for pages you don’t want to appear in search results like internal drafts or variations you aren’t using.

The meta tag is added to the <head> section of the relevant page and instructs search engines not to index the page.

Be mindful that this impacts the entire content and all crawlers.

If you need to block specific crawlers like AdsBot-Google add that in the meta tag instructions.

Das hreflang-Attribut für mehrsprachige Webseiten

If your website has multiple language versions use the hreflang attribute.

This tells Google which version is intended for which region and language avoiding duplicate content issues that can arise from essentially identical content residing on different country-specific domains.

Remember the correct ISO format for language and country codes is crucial for Googlebot to understand the information correctly.

Fazit: Ein gesunder Umgang mit Duplicate Content

Duplicate content can significantly impact your SEO.

While it might not automatically result in a Google penalty it can cause indexing problems lower your rankings and ultimately reduce your organic traffic.

A proactive approach is crucial.

Regularly audit your site using the tools mentioned above implement the technical solutions discussed and always strive to produce high-quality original content.

Remember achieving 100% unique content across the entire web is a nearly impossible goal – especially when it comes to external DC but following the advice above and focusing on creating genuinely unique content you will improve your search rankings and reduce the risk of duplicate content harming your website.
