Like it or not, AI-generated content is becoming more common across online platforms.
Publishing AI-generated content is considered risky, as Google has penalized AI-heavy sites, leading buyers to pay 39% more on average for sites with no AI content. Based on a study by the website buying and selling marketplace MotionInvest.com
In addition to popping up in Google results or Reddit posts, AI content is now a critical part of how websites that people are buying and selling get valued.
Although the use of AI isn’t necessarily a problem in and of itself, buyers know that there are both pros and cons to AI-generated content. And when money’s on the line - especially at higher price points - even a little uncertainty can impact the risk and resulting price a buyer is willing to pay.
To investigate this, we conducted a study on how the use of AI content (either fully, partially, or for grammar support) affects the sale price and time on market of websites based on real transaction data from Motion Invest.
Motion Invest is a website marketplace that offers content sites ranging from $800 to over $1 million, making it an excellent data source for our particular study. This platform specializes in vetted, profitable sites, making it a reliable source for studying how AI sites affect buyer behaviour.
Notably, it is the only marketplace that discloses and uses Originality.ai’s AI detector to verify if the website's content is AI-generated or human-written.
Based on 12 months of website sales data from Motion Invest, this study set out to:

Our analysis of Motion Invest’s website sales (defined as those that sold for $6,000 or more) from May 2024 to April 2025 reveals that, on average, the use of AI negatively impacted sale price.
More specifically, AI sites sold for lower sales multiples (a metric that compares sale price to monthly revenue). AI sites sold for an average of 1.5x annual revenue sale multiple, while those without AI use sold for 2.1x annual revenue.
This data suggests a strong correlation between the use of AI content on websites and buyer behavior. However, other valuation factors may also come into play here. Niche, traffic trends, monetization methods, and other factors can all impact the sale price.
Our study also revealed another pattern: Websites that had AI content took longer to sell than those that didn’t.
The difference in the average time on the marketplace proved to be quite significant. Sites that didn’t use AI spent on average 35 days on the market, while those that did sat for 54 days until they were sold.
On average, it took 19 more days, or 54% longer, to sell websites with AI-generated content than those without.
These results clearly indicate that buyers perceive AI-generated content as risky.
A decrease in sales multiples and an increase in time on market highlight the potential impact that AI has on website purchasing decisions, signalling a shift in how buyers evaluate digital assets.
Of course, AI use didn’t prevent sales in this study, which is good news for site owners who rely on some type of AI to help run their websites.
However, consistently lower sale prices suggest that sites with only human-written content are seen as more valuable/less risky. If that trend continues, sites with only human content could stand out even more in the market.
Tools like AI detectors and Site Scans could end up playing an important role here, as they can help both buyers and sellers flag potential instances of low-effort AI-assisted content.
Data Scope:
Exclusions:
Final Dataset: 28 qualifying website transactions.
AI Sites specified "Yes" to AI Disclosure: Sellers explicitly stated AI content was used (either fully, partially, or for grammar support).
Sites without AI specified "No" to AI Disclosure: Sellers stated they didn’t use AI, and this was verified by the team at MotionInvest with Originality.ai’s AI Checker scans of multiple pages.
Overall, the results of this study demonstrate that the presence of AI-generated content on websites is actively shaping buyer behavior.
If sellers want to avoid lower sale prices and longer times on market, it may be worth highlighting human-written content in website marketplace listings

No, that’s one of the benefits, only fill out the areas which you think will be relevant to the prompts you require.
When making the tool we had to make each prompt as general as possible to be able to include every kind of input. Not to worry though ChatGPT is smart and will still understand the prompt.
Originality.ai did a fantastic job on all three prompts, precisely detecting them as AI-written. Additionally, after I checked with actual human-written textual content, it did determine it as 100% human-generated, which is important.

Tools for conducting a plagiarism check between two documents online are important as it helps to ensure the originality and authenticity of written work. Plagiarism undermines the value of professional and educational institutions, as well as the integrity of the authors who write articles. By checking for plagiarism, you can ensure the work that you produce is original or properly attributed to the original author. This helps prevent the distribution of copied and misrepresented information.
Text comparison is the process of taking two or more pieces of text and comparing them to see if there are any similarities, differences and/or plagiarism. The objective of a text comparison is to see if one of the texts has been copied or paraphrased from another text. This text compare tool for plagiarism check between two documents has been built to help you streamline that process by finding the discrepancies with ease.
Text comparison tools work by analyzing and comparing the contents of two or more text documents to find similarities and differences between them. This is typically done by breaking the texts down into smaller units such as sentences or phrases, and then calculating a similarity score based on the number of identical or nearly identical units. The comparison may be based on the exact wording of the text, or it may take into account synonyms and other variations in language. The results of the comparison are usually presented in the form of a report or visual representation, highlighting the similarities and differences between the texts.
String comparison is a fundamental operation in text comparison tools that involves comparing two sequences of characters to determine if they are identical or not. This comparison can be done at the character level or at a higher level, such as the word or sentence level.
The most basic form of string comparison is the equality test, where the two strings are compared character by character and a Boolean result indicating whether they are equal or not is returned. More sophisticated string comparison algorithms use heuristics and statistical models to determine the similarity between two strings, even if they are not exactly the same. These algorithms often use techniques such as edit distance, which measures the minimum number of operations (such as insertions, deletions, and substitutions) required to transform one string into another.
Another common technique for string comparison is n-gram analysis, where the strings are divided into overlapping sequences of characters (n-grams) and the frequency of each n-gram is compared between the two strings. This allows for a more nuanced comparison that takes into account partial similarities, rather than just exact matches.
String comparison is a crucial component of text comparison tools, as it forms the basis for determining the similarities and differences between texts. The results of the string comparison can then be used to generate a report or visual representation of the similarities and differences between the texts.
Syntax highlighting is a feature of text editors and integrated development environments (IDEs) that helps to visually distinguish different elements of a code or markup language. It does this by coloring different elements of the code, such as keywords, variables, functions, and operators, based on a predefined set of rules.
The purpose of syntax highlighting is to make the code easier to read and understand, by drawing attention to the different elements and their structure. For example, keywords may be colored in a different hue to emphasize their importance, while comments or strings may be colored differently to distinguish them from the code itself. This helps to make the code more readable, reducing the cognitive load of the reader and making it easier to identify potential syntax errors.
With our tool it’s easy, just enter or upload some text, click on the button “Compare text” and the tool will automatically display the diff between the two texts.
Using text comparison tools is much easier, more efficient, and more reliable than proofreading a piece of text by hand. Eliminate the risk of human error by using a tool to detect and display the text difference within seconds.
We have support for the file extensions .pdf, .docx, .odt, .doc and .txt. You can also enter your text or copy and paste text to compare.
There is never any data saved by the tool, when you hit “Upload” we are just scanning the text and pasting it into our text area so with our text compare tool, no data ever enters our servers.
