Evidence-led keyword research. Smarter article planning. Greater clarity for publishers.
JustGroupLink Research is a publisher research software platform operated by Zileth Limited, a company registered in Nigeria. Our business is based in Umuahia, Abia State, Nigeria, and our website is https://justgrouplink.com.
We help bloggers, website publishers, independent editors, content teams and digital agencies investigate commercially relevant search topics, understand the limits of advertising data, and turn research findings into useful editorial plans. Our guiding belief is straightforward: a good article recommendation should explain what the evidence says, where it comes from, and what it does not prove.
Why JustGroupLink Research Exists
Publishing decisions often begin with a familiar question: What should I write about next? For an advertising-supported website, that question may be followed by another: Does this subject attract advertisers, and is there any sound reason to expect it to be commercially relevant to my audience?
Finding an expensive-looking keyword is not the same as finding a good article opportunity. Search demand varies by country and over time. Keyword phrases may be vague or unrelated to the intended audience. Advertiser CPC describes one side of an advertising market, while publisher earnings depend on different factors. Historical eCPM figures may begin unusually high when there have been very few ad impressions.
JustGroupLink Research is designed to bring these separate signals into a more understandable research process. Rather than presenting a long list of numbers without context, our aim is to help users identify relevant keyword clusters, examine supporting evidence, recognize uncertainty and develop well-structured topics for readers.
Our Mission
To make commercial keyword intelligence and publisher research more useful, transparent and accessible, helping content creators plan original, reader-focused articles without confusing estimated advertising indicators with guaranteed earnings.
Our Vision
We are working toward a research experience in which publishers can combine current market evidence with their own permitted historical performance data to make more informed content decisions—while retaining appropriate control over their sensitive business information.
What We Help Publishers Research
High-CPC Keyword and Market Discovery
Our research tools are designed to examine advertiser-side keyword indicators from authorized sources, including DataForSEO where configured. Depending on the data available, reports may contain estimated cost per click (CPC), monthly search demand, advertiser competition, search intent, research date and selected market.
We favor relevant, coherent queries over lists that merely contain impressive dollar amounts. Missing data should be identified, not invented, and an unusually high estimated CPC should not be mistaken for a publisher’s future income.

Original Article-Topic Research
A strong keyword can be the beginning of an article idea, but it is not a finished editorial plan. Our article-topic approach considers subject relevance, reader intent, meaningful supporting terms, country or local context where justified, and the practical problem an article should answer.
A topic recommendation may include a proposed headline, audience, geographic focus, keyword cluster, outline, frequently asked questions and facts an author should independently verify. These are editorial research aids—not automatically certified facts or publication-ready guarantees.

Private Historical Publisher eCPM Intelligence
Historical performance can offer context that keyword research alone cannot provide. Where the service is available, a publisher may manually export and upload an eligible CSV report containing article URLs or other supported article identifiers, reporting dates, ad impressions, advertising revenue and average eCPM.
The platform is designed to examine the publisher’s own information, including weighted historical eCPM and differences between short-lived spikes and performance supported by larger impression counts. Uploaded figures are publisher-supplied and are not automatically verified or endorsed by Google.
JustGroupLink does not require a direct Google Ad Manager or Google AdSense API connection for this manual-report workflow, and publishers should never submit their Google passwords or confidential revenue-share percentages.
Understand publisher eCPM intelligence.
Competitor and Public-Site Research
Publicly available information about other websites may help users identify editorial gaps and relevant search topics. Such analysis must distinguish observable public content and third-party search estimates from private business performance. We do not claim to know a competitor’s actual AdSense or AdX revenue merely from a website address.

Research Marketplace and Report Library
Our planned marketplace is designed to offer original, evidence-informed article-topic research reports. Eligible reports may draw on licensed keyword information and, where permitted, carefully protected historical topic-level insights. Customers purchase a new research product, not another publisher’s CSV file, individual earnings history or confidential account information.
Marketplace features, shared-data use and paid purchasing are activated only when their operational and rights requirements are satisfied. Availability should be confirmed on the live service before ordering.
Explore the research marketplace.
How Our Research Approach Works
Our intended process follows six practical stages:
- Identify the research objective. Choose the topic, target audience, country and type of report required.
- Collect authorized research information. Use supported keyword sources and, for private publisher analysis, information voluntarily supplied by the account holder.
- Check quality and relevance. Examine duplicates, ambiguous phrases, missing CPC, dates, geography and obvious mismatches.
- Assess commercial and editorial signals. Distinguish advertiser demand from historical publisher observations; consider sample size and comparability.
- Prepare an original topic brief. Suggest a clear title, structured outline, related questions and verification tasks for the publisher.
- Present the limitations. Identify estimates, historical observations, source dates and matters requiring independent checking.
This describes our research methodology and development objectives. Individual capabilities may differ while parts of the platform are still undergoing testing or phased activation.

The Important Difference Between CPC, eCPM and Page RPM
We believe publishers deserve a clear explanation of the numbers that appear in research tools.
- Advertiser CPC (cost per click) is a price-related indicator from paid search advertising research. It does not represent what an article owner will earn for an ad click or for 1,000 views.
- Publisher eCPM (effective cost per mille) expresses advertising revenue per 1,000 measured ad impressions: revenue ÷ ad impressions × 1,000.
- Page RPM (revenue per mille) expresses page revenue per 1,000 page views: page revenue ÷ page views × 1,000.
An article with a historically strong eCPM may perform differently at another time, on another website, or with a different audience. Likewise, an attractive CPC estimate can coexist with low organic search demand or weak publisher monetization.
We do not guarantee particular CPC values, eCPM, Page RPM, search rankings, page views, traffic levels, advertising revenue or profit.
Protecting Publisher Information
We recognize that historical advertising-performance reports can contain commercially sensitive information. Our approach separates two different activities:
Private analysis: A publisher submits eligible information to receive research for their own account. Their underlying CSV, article-level earnings and individual business records are not made available to competing publishers.
Optional research contribution: Where allowed by the relevant data rights and service terms, a publisher may separately authorize eligible derived insights to support wider research. A private upload does not automatically grant permission for shared commercial use.
The proposed contribution program includes a 15% discount on an eligible qualifying purchase after validation, subject to the published conditions and activation of the program. Consent must be specific and voluntary; it does not override a third-party provider’s contractual restrictions.
We seek to minimize unnecessary collection, restrict access, and provide meaningful information about retention and withdrawal. Technical protections and compliance requirements must be tested before those capabilities are offered publicly.

Countries and Audiences
Our research plans focus on country-specific opportunities, including the United States, United Kingdom, Canada, Australia, Germany, France, the Netherlands, Ireland, Sweden and Switzerland. Coverage and available metrics depend on the underlying provider and the research operation selected.
A country-wide keyword estimate must not be presented as a verified CPC or search-volume figure for an individual city or state. Localized article topics should be supported by additional, relevant evidence whenever possible.
Designed for Different Types of Publishers
Independent bloggers can investigate new article subjects and discover gaps in their content plans.
Advertising-supported publishers can examine the difference between advertiser-side estimates and their own historical revenue indicators.
Editors and content teams can structure research around reader intent, topic clusters, quality checks and useful outlines.
Digital agencies and publishing businesses can organize market-specific research and communicate the limits of estimates more clearly to clients.
Whether a user is exploring housing, insurance, education, relocation, technology or another topic, our approach begins with relevance to the reader—not with a promise of easy advertising income.
Clear Pricing and Research-Credit Protections
Our proposed service-credit system uses 100 credits as $1 in nominal research purchasing value. Credits are service-use units, not cash or an investment product; they cannot be withdrawn or transferred as money.
The current pricing design applies a 6× standard benchmark to direct research delivery costs, with an eligible 15% contribution discount structured to preserve a minimum 5× direct-cost benchmark on qualifying successful services, before other operating expenses. Actual quotations may vary by the specific research operation and should be shown before the customer approves a charge.
Our purchase-protection approach distinguishes temporary credit reservations from final deductions. Where the promised qualifying service cannot be delivered, applicable reserved credits should be released or restored in accordance with the Refund and Credit Policy. A valid market-feasibility report can legitimately find low demand; negative findings are not automatically provider failures.
Some payment, customer wallet and research-purchase features may remain unavailable while testing, merchant approvals and other readiness checks are completed.

Our Standards and Commitments
We aim to build around five lasting principles:
- Evidence before promises: Clearly distinguish observed data, independent estimates and editorial suggestions.
- Privacy by design: Treat sensitive publisher records as private unless a separately permitted use is expressly authorized.
- Useful originality: Develop coherent, reader-focused article opportunities rather than recycling raw keyword lists or copying someone else’s article.
- Honest product communication: Explain what is currently available, what is experimental and what requires further validation.
- Accountable customer support: Give users clear policy information and a way to report technical, payment, research or accessibility concerns.
Generated titles and outlines should always receive editorial review. Local laws, insurance terms, financial prices, medical information, immigration rules and other sensitive facts must be checked with reliable current sources before publication.
