In iSlay Panel, you can monitor content marketing projects, websites, editorial portals, blogs, e-commerce stores, landing pages, and campaigns with publishers.

Website monitoring – iSlay code can monitor all URL addresses within the selected website. To do this, you need to install the iSlay code on the main page of the website.

Monitoring selected subpages of the website – iSlay code can be installed on several selected subpages of the same domain. In this case, only the pages selected for the project will be monitored in the panel.

Campaign monitoring – In iSlay Panel, you can monitor a content marketing campaign conducted on multiple different portals. iSlay collaborates with the largest publishers. To monitor the campaign through the iSlay system, you need to agree with the publisher on the need to plug in the plugin when placing an order for a content marketing campaign.

iSlay Users decides how many and which URLs they want to monitor in their project. It is worth considering how to divide the content research into individual projects to obtain valuable information. Our clients most often divide projects into websites and campaigns.

The data collected using the iSlay code is stored for a period of 12 months, unless the account owner decides otherwise. Data from test projects is deleted 7 days after the end of the trial period and if the subscription is not paid.

iSlay is not authorized to use data obtained from connected websites. The user of the account is the owner and administrator of the data. iSlay is a data processor that performs calculations at the request of the user of the account. Upon registration, the user is required to accept the privacy policy agreement. Website owners use our software to process data regarding user behavior during visits to the site.

iSlay is an analytical system designed for content marketing purposes. Its main advantage is very accurate scrolling analysis, which sets iSlay apart from other dashboards. In addition, unlike most similar applications, iSlay analyzes all website users, not just a selected sample. iSlay’s algorithms have been developed through many years of experience in collecting and analyzing data on user behavior on websites. 

iSay and Google Analytics are complementary systems. It is best to use them together on the same webpage.

Yes, we provide support for our clients on how to use the system. The iSlay panel contains a lot of data, from which valuable insights can be drawn to optimize content on websites. We are happy to show how to interpret the data to learn more about users. We are passionate about internet research and happy to share our knowledge. Client needs inspire us when developing the tool.

If you have issues with data quality or technical questions, please contact

iSlay helps to understand how internet users perceive our website and which elements they pay attention to. When a website is not performing well, it can be difficult to understand what went wrong. iSlay allows you to verify many assumptions with data. By using our system, you will learn why users abandon reading text, abandon their shopping carts, leave at the checkout, or even before they get there.

All iSlay algorithms were created by the iSlay team. In some of them, we have used machine learning to capture dependencies between variables even more accurately. We do not use ready-made solutions. We design a completely new system based on the needs of our clients and our experience.

What can I measure with iSlay?

iSlay allows you to check if an article has been read. To do this, the depth of the page reached by the readers is examined. Subsequently, you can check the amount of time spent at each depth of the page.
Watch our videos in video section to learn how to check if an article has been read using iSlay.
iSlay allows you to check which elements of your publication have attracted the most attention from readers. The scrolling speed chart will show the specific location where users spent the most time.
Watch our video in video section to find out which parts of the article are interesting to readers.

To measure and determine if an article was read till the end using iSlay, you can track the scrolling behavior, and the engagement with specific elements on the page (such as videos, images, or interactive features). These metrics can help you determine if the user was actively engaged with the content and if they spent enough time on the page to indicate a thorough reading of the article.

To measure if an article has been read attentively using iSlay, you can look at several metrics:

  1. Scroll Speed: This metric measures how quickly a user scrolls down a page. If a user scrolls too quickly, it may indicate that they are not reading the content carefully. On the other hand, if they scroll slowly and deliberately, it suggests that they are paying closer attention to the content.
  2. Attention Break Point: This metric measures the point at which a user stops paying attention to the content. If a user stops engaging with the content early on, it may indicate that they are not reading it attentively.
  3. User Dynamics: This metric measures how the user interacts with the content, such as whether they scroll attentively, scroll up or just scroll too fast to read.

By analyzing these metrics, you can gain a better understanding of how users are engaging with the content on your website, and whether they are reading it attentively.

iSlay is able to measure the number of recommendations for each article by tracking how many times users share the link to that article. This information can be helpful in determining which articles are popular and which ones are not receiving as much attention.

Moreover, iSlay can also check through which channels the link was shared. For example, if the link was shared through messenger, social media, or email. This can provide insights into which channels are most effective for driving traffic and engagement to the website. It can also give an idea of the audience that the article is reaching through different channels.

By analyzing both the number of recommendations and the channels through which the link was shared, iSlay can help website owners and content creators to understand which articles are performing well and which channels are most effective for promoting their content.

iSlay recognizes users coming to the website from individual messaging apps, email and social media. This allows you to check if the link to the website is being recommended by its readers. iSlay is able to track the source of incoming traffic to the website, meaning it can identify if users are accessing the website from specific social media platforms or messaging apps. This information is valuable because it allows website owners and content creators to see which platforms are driving the most traffic to their website, as well as which ones are generating the most engagement and recommendations from users. By analyzing this data, they can make informed decisions about where to focus their efforts in promoting their content and reaching a wider audience.

To track from which messaging apps and social media platforms users came to the articles using iSlay, you can use the referral information provided by the analytics tool. This information shows the source of the traffic, which can include the name of the messaging app or social media platform. iSlay can then aggregate this data to show the number of users who came from each source and analyze which sources are driving the most traffic to the articles. By understanding which messaging apps and social media platforms are most effective at driving traffic, publishers can optimize their content distribution and marketing strategies.

To track how many users returned to the analyzed content, iSlay uses a unique identifier called a “fingerprint”. This identifier is created based on various user data, such as IP address, browser type, and operating system. By using the fingerprint, iSlay is able to recognize returning users even if they clear their cookies or switch devices. This allows for accurate measurement of user retention and engagement with the content.

iSlay is a tool that can analyze various aspects of user behavior on a website, including the sharing of articles through different channels. It tracks the number of recommendations each article receives and determines the specific channels used to share the link, such as messenger apps, social media platforms, or email. This information can be useful for website owners to understand the impact of their content on different social media and messaging platforms and to optimize their marketing efforts accordingly.

iSlay allows for measuring user engagement on a website by analyzing several parameters related to user scrolling behavior. The depth of scrolling indicates how far down the page the user has gone, while scroll speed and dynamics describe how fast and smoothly the user scrolled. The attention focus point is the point on the page where the user spent the most time, indicating where their attention was focused, while the attention drop point is the point on the page where the user lost interest and stopped scrolling. By analyzing these parameters, iSlay can provide insights into how users interact with a website and which parts of the content are most engaging or need improvement.


The iSlay code, once installed on the website, is used to collect and store data. It is responsible for gathering and sending data to the user’s iSlay account. The installation process involves copying and pasting a unique JavaScript code onto the website that you want to monitor. Only one iSlay code can be installed on a single website URL. The user decides how many and which website URLs they want to monitor in their project.

Open the text file sent by iSlay, e.g. v05_Islay_Plugin. In the HTML code of the page, find the end of the body tag: </body>. Select and copy the contents of the file. Place the cursor on the line directly ABOVE that tag. Paste the copied file contents. Publish the page.

Yes, iSlay code can be added to a page via Google Tag Manager (GTM). The process of adding the tag itself can be found here: It should be noted that iSlay code placed on a page using GTM may be treated as advertising code by ad-blocking programs (AdBlock). In this case, page view statistics will not include users with such programs.

If your website uses WordPress, you can choose the appropriate function during the iSlay project registration process. The system will automatically generate the iSlay code for installation in WordPress.

Open Chrome browser. From the menu on the right, select “More tools” and then “Developer tools”. In the console window, type “Islay” to identify the code on the page, then refresh the page. After reloading, the browser should display three code elements: png, script, and xhr. If the value in the Status column is 200, the embedded code is installed correctly.

  1. The iSlay code has not been installed on the website.

Solution: Follow our installation guide which will help you install the code.

  1. The code has been added incorrectly.

Solution: To check if you have correctly installed the tracking code, follow these steps. Avoid pasting the code in text editors and other text editing programs before pasting it onto the website. These programs sometimes alter the code.

If you do not see any requests in the developer tools, it means that the tracking code has not been installed correctly. Try adding the iSlay code again.

  1. No traffic on the website.

If there are no visible users in the Panel within 3 hours of installing the code, it may be due to low traffic on the website or a lack of installed code.

If tracking still doesn’t work, follow the installation guide to make sure the iSlay code is installed on the website.

iSlay uses asynchronous loading of JavaScript scripts, which significantly speeds up the loading of a web page. Asynchronous loading refers to a technique used in web development where resources, such as JavaScript files, are loaded in the background while the rest of the page is being rendered. This means that the browser doesn’t have to wait for the resource to be fully loaded before continuing to display the page to the user.

iSlay code is designed to be safe for websites, as it is a tracking code meant to collect website analytics data and not to harm the website or its visitors. The code is written to comply with industry-standard security practices and to avoid any potential vulnerabilities that could be exploited by malicious actors.

Additionally, iSlay code is typically hosted on secure and reliable servers, which are regularly monitored and updated to ensure maximum security. The company behind iSlay also employs security experts who continuously monitor for any potential security threats and take measures to prevent them.

It is important to note, however, that the security of any code or technology is not absolute, and there is always a risk of vulnerabilities being discovered and exploited. Therefore, it is recommended that website owners regularly update their website’s software, including any tracking codes like iSlay, to ensure maximum security.
