The paper's only evidentiary support for its central claim is a dense set of numeric assertions tied to references; when those references do not contain the asserted numbers, the argument has no independent support. I verified the specific example in §3-1: the SOMONITOR paper (arXiv:2407.13117) is about an explainable marketing-analytics framework and does not report the 25% engagement statistic attributed to it. The same reference is reused with different invented percentages elsewhere, and other citations point to generic Semantic Scholar pages rather than the named source. This is an internal correctness problem, not merely a disagreement with consensus: the manuscript's own evidence base fails verification. Because the paper is a review with no original experiments or formal verification, the inability to trace its quantitative claims leaves the central claim unsubstantiated. My concern therefore does not move the verdict; it reinforces the reader's REJECT.

A concrete failure occurs in §3-1, where 'businesses using LLMs for content production observed a 25% rise in engagement rates' is cited to [29], the SOMONITOR paper (Farseev et al., arXiv:2407.13117). SOMONITOR describes an explainable AI/LLM marketing-analytics framework and does not report a 25% engagement experiment; the same reference is later used in §5-1 for a 20% engagement increase and in §6-1 for a 35% sales increase, none of which appear in that paper. Similarly, §1-2 claims 'several orders of magnitude' improvement in engagement with citation [29], which is quantitatively implausible and unsupported by the cited source. Other examples show the same pattern, such as 'Forrester Research' claims cited to a Semantic Scholar page [33] rather than to any Forrester report. If these statistics cannot be traced, the paper's argument that LLMs deliver the claimed business outcomes is not established; the review becomes a rhetorical summary rather than an evidence-based guide.","agreement_with_reader":"agree"},"referee_report":{"model":"deepseek-v4-flash","summary":"This manuscript is a narrative review/survey of how large language models (LLMs) can be applied to marketing management. It covers personalization, content generation, customer engagement, market analysis, chatbots, campaign optimization, social media, ethics, challenges, and strategic recommendations, illustrated with several figures and numerous quantitative claims (e.g., 25% engagement increases, 40% response-time reductions, 35% sales lifts). The paper presents no original experiments, datasets, or case-study analyses of its own; its argument rests on citations to external sources and on figures that are asserted to show effect sizes. The conclusion recommends that marketers adopt LLM-based tools for personalization, automation, and predictive analytics while adhering to ethical frameworks.","tokens_in":34080,"tokens_out":2532,"duration_ms":26351,"significance":"The topic is timely and of practical interest, and the paper usefully catalogs a range of LLM applications in marketing. However, the significance is severely limited by the absence of any verifiable evidence base. The central claim that LLMs have 'revolutionized' marketing outcomes is supported almost entirely by numerical statistics attributed to sources that, on inspection, do not contain those statistics (e.g., §3-1 cites reference [29] for a 25% engagement rise; the cited SOMONITOR paper does not report such an experiment). The manuscript also contains unsourced figures (Figures 4, 5, 7, 9) and numerous unverifiable brand case studies. There is no reproducible code, no machine-checked derivation, and no original data. The paper's value as a strategic recommendation document is further undermined by pervasive text-quality issues, duplicated paragraphs, and references that are irrelevant or misattributed. For these reasons, the paper does not currently meet the standards of a scholarly contribution, although a rigorously sourced and methodologically transparent survey on this topic would be valuable.","major_comments":[{"comment":"The manuscript's central quantitative claims are attributed to references that do not support them. For example, §3-1 states that 'businesses using LLMs for content production observed a 25% rise in engagement rates' and cites reference [29] (SOMONITOR, Farseev et al.), but that paper describes an explainable AI/LLM framework for marketing analytics and does not report a 25% engagement experiment. The same reference is later used for a 20% engagement increase (§3-2), a 35% sales increase (§6-1), a 70% inquiry-handling capacity increase (§5-2), and a 20% campaign-management improvement (§5-1). Because the paper contains no original measurements, these statistics are load-bearing for the claim that LLMs deliver the asserted business outcomes; without traceable sources, that claim is not established.","section":"§3-1, §3-2, §5-2, §6-1"},{"comment":"Several quantitative claims are both implausible and unsupported. In §1-2 the authors write that engagement rates of businesses using LLM-generated content have been 'several orders of magnitude above traditional methods,' citing [29], which reports no such result and which would be an extraordinary effect that no controlled study in marketing supports. Similarly, §4-1 claims that automated LLM analysis reduces the time and effort needed for analysis 'by 99%,' with no citation or methodology. These and other unsourced numbers (e.g., the '39% increase in customer retention' in §3-2 and the '50% decrease in average response times' in §5-2) are presented as empirical facts. The authors should either replace them with verifiable, appropriately cited sources or substantially temper the claims.","section":"§1-2 and §4-1"},{"comment":"Several figures are presented as evidence supporting the paper's central effectiveness claims, but no data, methodology, or source is provided. Figure 4 is said to show 'a substantial increase in customer engagement, decreased marketing costs, and the sustained growth of ROI over time'; Figure 5 is said to show customer engagement increasing 'immediately after the usage of LLMs'; Figure 7 compares ROI with and without LLMs; and Figure 9 is a 'heatmap of LLMs' impact in marketing areas.' No description of how these figures were constructed, what datasets they use, or where the underlying measurements come from is given. If these are illustrative schematics, they should be labeled as such and not used to support quantitative conclusions; if they are based on real data, that data must be disclosed.","section":"Figures 4, 5, 7, 9"},{"comment":"The case studies of Coca-Cola, Amazon, Netflix, Nike, Spotify, Sephora, Starbucks, and Unilever report specific performance improvements (e.g., 30% engagement for Coca-Cola, 50% resolution-time reduction for Amazon, 40% retention for Netflix, 25% ROI for Unilever) with citations that are generic or unrelated. For instance, the Coca-Cola claim is cited to [33], a Semantic Scholar page on 'LLMs for Conversational AI,' which does not contain a Coca-Cola case study; the Netflix claim is cited to [77], an undergraduate-style report, not a primary source. No case-study methodology, dates, or link to original company disclosures is provided. These unverifiable success stories are central to the paper's recommendation that marketers adopt LLMs, so they need to be either properly sourced or removed.","section":"§10-1 and §10-2"}],"minor_comments":[{"comment":"The title promises 'Applications, Future Directions, and Strategic Recommendations,' which is fine, but the organization is repetitive: several sections begin with nearly identical sentences, and some headings are duplicated (e.g., 'Personalization and Customer Engagement' appears twice in §1-1, and §10-2 contains repeated bullet points with identical lead-ins).","section":"Title and structure"},{"comment":"The introduction includes a long block of references [1]–[23] that are almost entirely about the RAIN medical protocol and unrelated AI topics; these are irrelevant to marketing and should be removed.","section":"§1 Introduction"},{"comment":"The heading 'Lesions Learned and Best Practices' contains a typo; it should be 'Lessons Learned and Best Practices.'","section":"§10-2"},{"comment":"The first sentence of Section 4 ('Dalle 2 is the tech again Develops a hardware technology that cater for a what under of space called AI in marketing') is incoherent and appears to be a generation artifact; it should be rewritten or deleted.","section":"§4 opening"},{"comment":"There are many duplicated sentences and orphaned phrases, such as 'So, in short, what is one of the ways you can use NLG?' and 'Above all, Digital Twins fortify customer interaction,' which interrupt the narrative and should be removed.","section":"§5-1 and elsewhere"},{"comment":"Several references are incomplete or mislabeled.

The general claim that LLMs can improve marketing operations is plausible, but this paper doesn't establish it.\n\nWhat it does well: the paper organizes a broad set of LLM marketing applications into familiar buckets—content creation, personalization, market research, customer service, campaign optimization, social media, ethics. For a nontechnical reader wanting a high-level map of the landscape, the structure is accessible. The ethics section covers bias, transparency, privacy, and consent at an introductory level. The strategic recommendations are generic but not wrong.\n\nWhat's wrong: the evidence base. The paper repeatedly cites specific numbers—25% engagement lifts, 40% response-time reductions, 35% sales increases—as if they came from empirical studies, but many are misattributed or unverifiable. The stress-test note is accurate: §3-1's 25% engagement increase is credited to SOMONITOR [29], which reports no such figure; the same reference is later used for a 20% and a 35% result. A \"Forrester Research\" claim is cited to a Semantic Scholar page. There's also a \"several orders of magnitude\" engagement improvement with no sourcing at all. These aren't minor lapses; the paper has no original data, so its argument rests entirely on these external numbers. When those numbers can't be traced, the review becomes rhetoric.\n\nThe editorial quality is poor enough to matter. The text contains a duplicated \"Personalization and Customer Engagement\" header, a repeated Figure 3 caption, at least one ChatGPT remnant (\"You are related to data till October 2023\"), a stray sentence about Dalle 2, and a block of self-citations to the authors' own medical RAIN-protocol papers that have nothing to do with marketing. Possibly the most telling detail: the same reference appears twice in the bibliography as [29] and [46].\n\nWho this is for: a practitioner wanting a buzzword-level overview might find the structure useful, but the unsupported metrics would mislead more than help. There is nothing here for a researcher.\n\nRecommendation: desk reject. If the authors want to salvage it as a review, they need to remove every unsupported quantitative claim or replace them with verifiable primary sources, strip the irrelevant self-citations, and fix the repeated passages. As submitted, it doesn't meet the bar for peer review.","headline":"A sloppy narrative review whose load-bearing statistics are misattributed or unverifiable; desk-reject despite the plausibility of its topic.","tokens_in":34615,"tokens_out":3187,"would_cite":false,"duration_ms":31610,"reading_group":"no","serious_thinker":"no","would_accept_peer_review":false},"rs_alignment":null,"lean_confirmation":null,"pith_extraction":{"msc":[],"pacs":[],"model":"deepseek-v4-flash","headline":"Large language models have become the central engine of modern marketing management, this review argues.","keywords":["large language models","marketing management","hyper-personalization","content automation","predictive analytics","customer engagement","ethical AI","sentiment analysis"],"falsifier":"Check reference [29] (SOMONITOR) and reference [33] for the claimed 25% engagement increase and 40% response-time decrease; if those figures are absent, the paper's evidence base fails.
