Online marketing has emerged as the backbone of contemporary marketing, enabling businesses to reach a global audience with ease. The sector is afflicted with some serious issues, including fraud, transparency, and privacy. Blockchain has emerged as a powerful solution to the problems of security, transparency, and the enhancement of efficiency. With blockchain technology used in online advertising, companies can optimise ad spending, authenticate content, and provide a secure platform for advertisers, consumers, and publishers.
Learning Blockchain Technology
Blockchain is an open, public electronic record book that authenticates and makes transactions transparent. A transaction is entered into a block and is linked with the other ones, and it's a chain that is irreversible after execution. Blockchain takes its inception from cryptocurrency, but nowadays it is being used in all industries, like digital advertising, since it can authenticate transactions in a middleman-less scenario. The decentralised network of Blockchain shuts the doors for fraud and tampering, and therefore, there is a better and efficient method of advertisement.
Big Issues in Digital Marketing
Some big-sized issues in digital marketing are impacting its authenticity and effectiveness.
Ad Fraud and Impersonation
Ad fraud is the largest problem with online ads, and the criminals are making companies lose billions of dollars every year. The bots are used to create fraudulent traffic because they create artificial impressions and clicks and trick the advertiser into thinking that they are targeting human beings. This is followed by wastage of advertisement expenditure as well as suboptimal campaign optimizing.
Lack of Transparency
The advertisers are not able to keep track of where they are putting their ads, and this results in wastage. Ad networks and intermediaries control ad placement, and therefore, one cannot determine whether the ads reach the intended audience. It makes it outdated and results in mistrust among publishers and advertisers.
Privacy and Data Security Concerns
With increasing concern for data privacy, consumers today more than ever closely monitor the information utilised to create online ads. Web advertisement websites scrape and profit from most users' data without their knowledge, inviting privacy intrusion and regulatory problems.
High Intermediary Costs
Traditional digital marketing utilises intermediaries such as ad networks, exchanges, and agencies, and all these take a lion's share of the revenue. All of these are being financed by the advertisers and robbing publishers of their profit.
How Blockchain is Disrupting Digital Advertising
Blockchain technology fixes these problems in real life by providing transparency, security, and efficiency.
Preventing Ad Fraud
By authenticating and verifying every ad impression and click using blockchain, advertisers can separate fake bots from real users. With blockchain backing transactions in an immutable state, anything fake can be quickly identified and removed. Therefore, only real interactions are rewarded.
More Transparency and Trust
Blockchain can track the placement and performance of ads in real time, and thus, advertisers will be assured that their ads are being shown on real sites. By keeping all transactions within a distributed accounting book, blockchain makes spending on ads fully transparent, and hence, middlemen manipulation as well as disguised charges are a thing of the past.
With blockchain, people can be more independent with their data. Rather than platforms harvesting and selling people's data without them knowing, blockchain can have people give only what is needed while remaining anonymous. This is compliant with data protection laws such as GDPR, enhancing user trust and compliance.
Lowering Costs by Removing Middlemen
Blockchain smart contracts allow direct payment from advertisers to publishers without an intermediary. It is cost-effective by itself and allows revenue sharing in a ratio, and thus, digital marketing is efficient as well as cost-effective.
Enabling Micro-Payments and Reward Ads
Blockchain enables customers to be compensated by advertisers for directly interacting with ads in the form of cryptocurrency or micro-payments of tokens. Blockchain enables an interactive experience with ads where customers are allowed to view adverts voluntarily and get compensated for them.
Use of Blockchain in Daily Life to Advertising
Several creative businesses already use blockchain in their online advertisements:
- Brave Browser & Basic Attention Token (BAT): Brave pays advertisers in BAT tokens for viewing ads openly and transparently.
- AdEx: Blockchain-powered ad exchange platform where publishers and advertisers can trade directly without fraud.
- Lucidity: Blockchain-powered ad analysis platform where advertisers have the opportunity to build fraud out and optimise campaign performance.
Future of Blockchain in Digital Advertising
Blockchain for Internet advertising is only in the beginning phase, and the opportunities here are tremendous. As more and more businesses realise the might of transparency, fraud protection, and data integrity, ad solutions via blockchain would be the new standard. Some futures in development are AI-powered blockchain ad networks, real-time bidding transparency, and user-based data monetisation models.
Conclusion
Blockchain technology is transforming the function of online advertising by solving its worst nightmares, i.e., fraud, transparency, and data security problems. Blockchain makes it possible for businesses to build a safer, more efficient, and trustworthy system of advertisements. The more the utilisation of blockchain, the more transparent, cost-effective, and user-driven digital marketing will be for the good of consumers, publishers, and marketers in the end.
