For the full breakdown, see our best 20 Gallon Saltwater Tank guide.
Here’s my thinking process for crafting the article:
**1. Keyword Classification**
The keyword is “How to Set Up a 20 Gallon Saltwater Tank?” — this is a pure how-to/setup keyword with one legitimate method. Official-source fidelity governs, but the research brief provides the exact trusted procedure, so I’ll transcribe those steps faithfully. Not a workaround keyword, so the official path leads naturally.
**2. Structural Planning for the Length Override**
With a 750–950 word target and max 4 H2s, I planned:
– H1 + bolded snippet (≤150 chars)
– Opening block (answer-first)
– H2 #1: “What You Need…” — equipment list
– H2 #2: Question-format “How Do You Mix Saltwater Correctly?” (fits the 1–2 question heading rule)
– H2 #3: “Step-by-Step Setup…” — procedure with table after 40%
– H2 #4: “FAQs” (counts toward the 4 H2 max)
– Closing mistakes paragraph (no separate checklist section per override)
– References footer
**3. Key Rule Applications**
– **Citation markers:** Removed all numbered citations; wove “Bulk Reef Supply’s setup guide” naturally into sentences.
– **Keyword handling:** H1 carries the exact keyword with question mark. Body converts to indirect clauses — “a 20-gallon saltwater tank setup is mostly about doing a few things in the right order.” Snippet crisply answers without repeating the keyword (checked: 127 chars, no exact keyword).
– **Variant H2:** “Step-by-Step Setup for a 20-Gallon Tank” carries ~50% variant with topic-derived modifier, not a template default.
– **Tables:** Only one table (per override) — placed as the data backbone after the steps — compressed parameter targets, 7 rows, 3 columns, descriptive headers.
– **Internal link:** Placed in the equipment section where a reader ready to buy would benefit, with natural anchor “our tested list of the best 20-gallon saltwater tanks.”
– **External link:** One deep link to Bulk Reef Supply’s setup guide, placed in the 30–70% zone within the steps section.
– **Title length:** “How to Set Up a 20 Gallon Saltwater Tank? | Steps & Gear” = 56 characters, under the 60 limit.
– **FAQ:** 3 questions only, each 40–70 words, not repeating keyword verbatim.
– **Success cues:** Mixed salinity “looks clear” and tank “runs clear” cues included.
**4. QA Passes**
– **Reader pass:** Answer-first throughout; steps are executable with bolded UI elements; no fluff.
– **Bing/Copilot pass:** Exact keyword in H1 and first paragraph; sentence-cased theme phrases in body; one question-format heading; entities named consistently; sourced facts attributed properly.
– **Ad-reviewer pass:** Text-led, single table only, no blocked layout, end-placed consolidation.
The final word count lands around 780 words before FAQ, within the target range.
