Duplicate content is one of the most common technical SEO problems that can hurt your website's rankings without you knowing it. When a lot of pages have the same or very similar content, search engines have a hard time figuring out which page should be at the top. This confusion can weaken ranking signals, make it harder for people to find your site naturally, and waste your crawl budget. Fortunately, crawling websites is a reliable way to find and fix duplicate content.
We will show you how to find duplicate content problems and how an KWT SPIDER SEO Crawler Tool can help your SEO performance in this guide.

What does it mean to have duplicate content?
Duplicate content is when the same blocks of content show up on more than one URL. It can be there:
On the same website (internal duplication)
On different websites (external duplication)
Some common reasons are:
Parameters in the URL
Pages that are easy to print
Versions of HTTP and HTTPS
Versions with and without WWW
Filters for products on eCommerce sites
Copied meta descriptions and titles
Search engines might not punish duplicate content directly, but they might not show duplicate pages in search results. That means less traffic and less authority.
Why It's Important to Crawl Websites
You can scan your whole site the same way search engines do with website crawling. You can get structured data about the following things by using a professional SEO Crawler Tool:
Titles of pages
Meta descriptions
Tags for headers
Tags that are canonical
Codes for status
Count of words
This information makes it easy and quick to find patterns of duplication.
Step 1: Do a full crawl of the website
To begin, open your SEO Crawler Tool and type in the URL of your website. Let the crawler look at all the pages it can reach. Look over the duplicate content reports after the crawl is done.
Most advanced tools have filters for:
Page titles that are the same
Copy meta descriptions
Duplicate H1 tags
Percentage of similar content
This is the basis for finding problems with duplication.
Step 2: Find Duplicate Meta Data
It's common for meta titles and descriptions to be copied and pasted across pages by mistake. You can do the following with an SEO Crawler Software:
Put pages with the same title in order
Remove duplicate descriptions
Export reports for large-scale analysis
Search engines may have trouble figuring out what each page is for if they all have the same title. The title of each page should be different and include keywords.
Step 3: Look at the structure of the URL
Many problems with duplication come from different versions of a URL, such as:
example.com/page
example.com/page/
example.com/page?ref=123
A good SEO Crawler Utility points out duplicate versions and URL parameters. You can then do:
Tags that are canonical
Redirects 301
How to handle parameters in Search Console
This makes sure that search engines only index the version you want.
Step 4: Check how the Canonical Tag is set up
Canonical tags let search engines know which version of a page is the main one. Check during website crawling:
There are canonical tags present
They go to the right URL.
There are no standard loops
Setting up a canonical incorrectly can make duplication problems worse. An advanced SEO Crawler Tool makes it easy to check canonical data on a large scale.
Step 5: Check for Similar Content
Some pages may not be exactly the same, but they are very similar. This happens a lot in:
Pages for locations
Different kinds of products
Pages for blog categories
Content similarity checks are a common feature of website crawling Software. If a lot of pages have almost the same content, think about:
Putting pages together
Rewriting text
Adding something special
Using canonical tags
Unique content helps with rankings and getting people to interact with your site.
Step 6: Make improvements and keep an eye on them.
Run another crawl after fixing the duplicate problems. It is important to keep an eye on things all the time. This is where professional tools like kwtspider come in handy for regular technical SEO audits.
You can check by running your SEO Crawler Tool again:
There are no more duplicate titles.
Canonical tags are set in stone
Redirects are working as they should
Duplicate URLs are combined.
SEO isn't something you do once; you have to keep an eye on it.
The advantages of finding duplicate content early
Fixing duplicate content makes things better:
How well does crawling work?

Relevance of keywords
Combining page authority

Not following best practices for pagination
Taking down pages without proper redirects
This software gives a full technical overview, which helps avoid these mistakes.
