Topic sentence diagnosis
Each selected paragraph is checked for a controlling claim rather than a broad topic announcement. The review identifies vague wording, competing ideas, unsupported claims, and sentences that merely name the subject.
Since 2003
BestEssays reviews whether each topic sentence makes a clear claim and limits the paragraph to evidence that supports it.

Each selected paragraph is checked for a controlling claim rather than a broad topic announcement. The review identifies vague wording, competing ideas, unsupported claims, and sentences that merely name the subject.
The order can provide a revised topic sentence for each paragraph, with alternatives when different levels of emphasis are possible. These options serve as models for the student’s own revisions.
Feedback marks material that supports the topic sentence, material that needs explanation, and material that belongs elsewhere. This shows how the sentence controls the paragraph rather than simply opening it.
Notes explain how the paragraph claim connects to the thesis, the previous paragraph, and the next step in the argument. Transition wording is addressed separately from the topic sentence’s main claim.
A weak opening often identifies a subject without taking a position on it: “Social media affects communication.” That wording leaves the paragraph open to almost any point about social media or communication. A usable topic sentence narrows the relationship: “Workplace messaging platforms speed routine coordination but can blur expectations about employee availability.”
The second version controls the paragraph. Evidence about response speed, coordination, availability, or boundaries may fit. A long discussion of advertising algorithms probably does not. Topic sentence help focuses on making that boundary visible.
The paragraph is read as a unit. Its opening claim is compared with every supporting sentence, example, quotation, and concluding statement. If several sentences cannot be connected to the opening claim, the problem may be an imprecise topic sentence, unrelated evidence, or two paragraph ideas combined into one.
The resulting notes separate sentence-level wording from structural problems. This prevents a polished opening from hiding a paragraph that still contains competing claims.
The appropriate form depends on the paragraph’s job. An analytical paragraph needs an arguable interpretation. A compare-and-contrast paragraph should name both subjects and the basis of comparison. A cause-and-effect paragraph should state the proposed relationship rather than list two events. A literature paragraph should make an interpretive claim instead of announcing a character or theme.
Body paragraphs in research writing may include a source-based claim, but the topic sentence should not become a quotation dump. Evidence normally follows the claim and is then explained. In an introduction or conclusion, the opening sentence serves a different purpose and should not be treated automatically as a body-paragraph topic sentence.
Feedback can be arranged as an annotated draft, a paragraph-by-paragraph table, or a standalone list of original and revised sentences. In a .docx draft, comments and tracked wording changes can be attached to the relevant paragraph. When working from a fixed-layout PDF, notes can be keyed to page and paragraph numbers.
Each entry can use the same labels: original sentence, diagnosed issue, revised model, scope note, and alignment note. This format makes it possible to compare the revision with the paragraph instead of reviewing isolated sentences.
Yes. Provide the paragraph, thesis, assignment prompt, and any instructor comments available. The surrounding material is important because a sentence cannot be evaluated accurately without knowing the claim it must support.
No. Repeating one formula can make an argument mechanical and may hide differences between analysis, comparison, definition, evidence review, and counterargument paragraphs.
Only when the assignment and source use require attribution. Topic sentences usually present the paragraph’s controlling claim, while quotations, data, and citations appear in the supporting sentences.
The BestEssays order form offers deadlines from 3 hours to 10 days. The appropriate choice depends on the number of paragraphs, the condition of the draft, and the depth of feedback requested.
There is no fixed revision window promised. Contact support, and the request will be reviewed individually. The deciding issue is whether the requested change matches the instructions supplied before writing started.
Refund requests are reviewed case by case and in detail. A refund is not automatic, and no fixed percentage, tier, or time limit is promised.
