Discussion

Web browsers traditionally loaded HTML content synchronously. This process involves:

• Loading the entire HTML page first, allows the browser to display all content.

• After that, other elements like images are loaded.

However, when external sources (like OpenAD Protocol tags) are added to a page:

• The browser must fetch the HTML from external sources before loading the page.

• If the external source takes time or there are multiple sources, it can delay the page load.

• This causes external content to "block" the loading of the main page content.

To avoid this issue, OpenAD Protocol provides methods to prevent banners from blocking the main site content.

How-To

Option 1: Use Asynchronous or iFrame Tags

The easiest way to prevent OpenAD banners from delaying website content is to:

• Use Asynchronous JS Tags or iFrame Tags.

• These tags load banners separately from the main content.

• Simply generate the tag for the zone you want to display banners, place it in your HTML, and the banners will load asynchronously.

Option 2: Bottom Loading & CSS Positioning

If you prefer not to use asynchronous tags:

• Place the banner tag at the bottom of the HTML page.

• Use CSS to position the banner where you want it on the page.

• While the browser will still show it's loading until banners appear, the main website content will load first.

• This method mimics asynchronous loading, ensuring the main content appears before banners.

Type of Roles

Advertiser

A person or company who wants to display on-line advertising - generally, at a cost.

Publisher

A person or company who has ("publishes") a website (or some other form of on-line property) on which they wish to display on-line advertising (generally, from advertisers, and for a fee; but publishers do also display ads for free, either from advertisers, or to promote their own services when there are no paid ads to display).

Types of Advertising

Banner — an ad creative.

Campaign — an advertising campaign with a selected ad type.

General Settings

Country — the country of the user from which the ad request was made.

Budget — spending limit in USD₮ for the campaign.

Language — the language of the Telegram user's interface.

URL — the web address of the advertised resource.

USD₮ - Tether (USD₮) is a stablecoin pegged to the US dollar exchange rate in a 1:1 ratio, used to simplify cryptocurrency trading and minimize volatility.

Reports

Click — A click is whenever someone clicks on an ad. Click counts are sometimes filtered to prevent repeat clicks or other forms of fraud by publishers trying to raise revenues by repeatedly clicking on ads.

CPM (Cost per mile) — is the cost per 1,000 impressions (for the advertiser). For the publisher, this can also be thought of as the revenue per 1,000 impressions.

CPC (Cost per click) — is the cost per click (for the advertiser). For the publisher, this can also be thought of as the revenue per click.

CPA (Cost per acquisition) — is the cost per acquisition or action (for the advertiser) - that is, where the advertiser pays based the required action being performed after either clicking on an ad, or less commonly, after having seen an ad impression. For the publisher, this can also be thought of as the revenue per acquisition or action.

CTR (Click-Through Rate) — is the percentage of users who clicked on the ad relative to the total number of users who saw the ad.

Impressions — In on-line advertising, and impression is a view, or an "opportunity to see" an ad. Every time an ad is displayed (rendered) on a website site or device, this is an "opportunity to see" the ad, and counts as an impression.

Spent — the amount you spent.

This document provides instructions on how to access the SDK in native HTML (Games, etc.).

Step #1. Load SDK

#1. Load the SDK in the body of html, the code is as follows:

We recommend to add your application version number or release timestamp after JS to obtain the latest JS SDK for your application. E.g.,

https://protocol.openad.network/sdkloader.js?t=your-app-release-timestamp

https://protocol.openad.network/sdkloader.js?v=your-app-version

The script will pick OpenAD node for your end users, and load proper version of OpenAD SDK for you.

#2. Add DOM placeholder for Ad banner

zoneld="158", 158 is a demo zoneld, please use your own "zoneId". publisherld="49", 49 is a demo publisherld, please use your own "publisherld" feel free to define your own banner style

OpenAD SDK will get ad banner for your end users and has it rendered in the DOM placeholder.

In traditional web applications, you can see OpenAD banner been rendered.

Step #2. Get Ad Info

Please embed the following code into the body.

Event Callback

If the user is already logged in,

1. Initialize user data (optional, not need to set in TMA)

window.openAdNative.initUserInfo(data);

1. Get Ad Info

window.openAdNative.getAD();

1. Close AD

window.openAdNative.destroy(window.openAdNative.adInfo);

Symptoms

Banners deliver over HTTP, but will not deliver over SSL (HTTPS).

Troubleshooting Process

Step 1: Check for HTML Banners with HTTP Content

Ensure that your HTML banners don’t include any content (like images or CSS files) served over HTTP. OpenAD Protocol excludes any banners with HTTP content when delivering over HTTPS to avoid warnings from browsers about mixed content.

Step 2: Solution

Update your HTML banners to use HTTPS for all included content, ensuring seamless delivery on HTTPS-enabled pages.

Step 3: Check for HTTP to HTTPS Server Redirects (3xx) when using the Asynchronous JS Tag

When using the "Asynchronous JS Tag" for delivery, check if the issue is related to enforcing SSL on an HTTP page. The Asynchronous JS Tag automatically uses the same protocol (HTTP or HTTPS) as the page where it’s embedded:

• If placed on an HTTP page, the tag will connect to your OpenAD Protocol instance using HTTP.

• If your OpenAD Protocol returns an HTTP 3xx response code, indicating a redirect to HTTPS, this will not work.

The Asynchronous JS Tag first calls OpenAD Protocol to retrieve data which is required to update the tag placeholder, so that the relevant banner can be loaded. For this to work, OpenAD Protocol returns some headers.

However, most browsers will perform the request to the Asynchronous JS Tag as a CORS preflight request. . This means that an Asynchronous JS Tag embedded on an HTTP page must be able to access OpenAD Protocol's sdkloader.js script over HTTP.

If you have configured your webserver to enforce the use of SSL by redirecting requests over HTTP to HTTPS, then your options are:

• Ensure that your Asynchronous JS Tag is only ever embedded on sites delivered using SSL;

• Disable the redirection to SSL for the sdkloader.js script, so that this can be accessed via both HTTP and HTTPS; or

• Use a different tag type.

Easy embedding

Step #1. Load SDK

Load the SDK in the body of html, the code is as follows:

We recommend to add your application version number or release timestamp after JS to get the latest JS SDK for your application. E.g.,

https://protocol.openad.network/line/sdk.loader.js?t=your-app-release-timestamp

https://protocol.openad.network/line/sdk.loader.js?v=your-app-version

The following global vairables will be loaded with 'https://protocol.openad.network/line/sdk.loader.js'.

• openADSdkLoader.hostURL , node api url to serve end user. e.g., 'https://6bf9546ea5.api.openad.network'.

The script will pick OpenAD node for your end users, and load proper version of OpenAD SDK for you.

Step #2. Add DOM placeholder for Ad banner

zoneld="158", 158 is a demo zoneld, please use your own "zoneId" parameter; publisherld="49", 49 is a demo publisherld, please use your own "publisherld" parameter; feel free to define your own banner style.

OpenAD SDK will get ad banner for your end users and has it rendered in the DOM placeholder.

In traditional web applications, you can see OpenAD banner been rendered.

!!! OpenAD only support ONE DOM placeholder in one web page.

Enjoy the OpenAD ecosystem !!!

Step #3. Init OpenAD Resource

In most SPA (single page application) web frameworks, DOM objects are rendered dynamically. Thus, the ad banner shall be init manually, the init js call will render ad banners to predefined DOM placeholder.
