Key Takeaway
An SEO content writing agency reveals its real process during the sales call. Watch two things: how the team talks about keywords and what their reports actually measure. Get those wrong and you fund twelve months of content that never touches revenue.
Myth: Keyword density is how pages rank
Density was a lever in 2008. Search engines now read meaning and internal links. A page that repeats “best CRM for small business” forty times competes against a page that says it four times and covers the topic with clean structure.
Ask the agency to explain one sample. If the answer is “we hit a 1.5 percent density”, they are writing for an old algorithm. If they talk about search intent and related questions, you are in better hands.
The test that matters
Send a one-paragraph brief on a topic you know cold. Give them two days. Read whether they caught the obvious follow-up question a buyer would ask. That single reply tells you more than a slide deck.
Myth: A large portfolio proves quality
Portfolios are marketing; any agency can list fifty logos. The portfolio that matters shows the brief and the result. A thin portfolio with three deep case studies beats a wall of brand names every time.
Look for the before number and the after number. A page-one ranking for a low-competition term means little. Organic sessions to the pricing page rising from 400 to 1,300 in five months is a fact you can check.
How to read samples
Pick a sample and read the first sentence. Strong writers lead with the answer, while weak writers warm up with a paragraph about the industry.
Myth: Freelancer chains destroy content
Every agency uses freelancers, which is normal and often good. The failure starts when nobody owns quality between the writer and your inbox.
A chain has one weak point: the missing editor. When a brief is loose and no senior writer reviews the draft, you pay agency rates for first-draft text. Ask who edits. Ask for that person’s name and a sample of their notes on a real draft.
Warning sign
If the person who sold you the service never touches the work again, you are paying for a project manager and getting no content team.
Myth: Vague reports are just how SEO works
Reporting that tracks word count and keyword positions is noise. Those numbers do not connect to money.
Ask for a report sample up front. It should map content to conversions and pipeline. If the agency cannot show a single metric tied to revenue, they are measuring effort.
Build a simple scorecard
Pick one outcome per month, such as organic leads from a landing page or demo requests from a blog post. Put it in the report. When the number moves, you know the content worked.
Myth: The lowest price per word saves money
Cheap copy gets rewritten. A $40 post that needs a full rewrite costs $80 plus your time. The real cost is the buyer who never opens the page.
Price the whole loop, from the first brief through publishing and one round of optimization. Agencies that hide parts of the process look cheapest on paper and cost most in practice.

Myth: You must commit to a retainer to test them
You do not. A retainer is for after they prove the process.
The one thing to do before you sign
Run a paid pilot: two articles on your topic, scored against a checklist covering research depth, editing quality, reporting accuracy and deadline reliability. It costs less than a month of a bad retainer and exposes the real agency behind the pitch.
When a vendor passes, you keep them. When they fail, you walk away without a contract to argue over.
