The verdict in three sentences
Content is an asset: unlike advertising that stops the moment the budget does, a well-ranked article generates leads for months. The price to pay is patience: expect 3 to 6 months to rank and see the pipeline fill. Over time, cost per lead falls 3 to 5 times below paid campaigns.
Content levers and their yield
Not all formats are equal. The SEO blog captures existing demand; LinkedIn builds awareness; case studies reassure before purchase.
| Lever | Time to result | Cost per lead (est.) | Conversion rate |
|---|---|---|---|
| SEO blog | 3-6 months | 15,000-40,000 FCFA | 2-5 % |
| Case studies | 1-2 months | 20,000-50,000 FCFA | 8-15 % |
| Organic LinkedIn | Immediate-2 months | 10,000-30,000 FCFA | 3-8 % |
| Lead magnet | 1-3 months | 5,000-25,000 FCFA | 15-30 % |
The lead magnet (guide, template, downloadable checklist in exchange for an email) shows the best conversion rate and feeds a list you can re-engage.
Content vs paid advertising over time
Advertising delivers immediate but volatile results; content starts slowly then compounds. Over 12 months, the cost-per-lead gap widens sharply.
| Month | Cost per lead — Ads | Cost per lead — Content |
|---|---|---|
| Month 1-3 | 40,000 FCFA | 80,000 FCFA |
| Month 4-6 | 40,000 FCFA | 35,000 FCFA |
| Month 7-9 | 40,000 FCFA | 20,000 FCFA |
| Month 10-12 | 40,000 FCFA | 12,000 FCFA |
Content costs more upfront (production time with no result), then becomes the most profitable channel once ranking is earned.
Mini case study
Omar runs a web agency in Thiès. He publishes 2 SEO articles a month and 1 case study a quarter, plus an "E-commerce site checklist" lead magnet. After 6 months his blog generates 300 organic visits a month; the lead magnet converts at 20 %, i.e. 60 emails collected. Across these contacts, follow-up turns 4 leads into clients at 1,000,000 FCFA, i.e. 4,000,000 FCFA generated for a production cost of about 600,000 FCFA over the half-year — a 150,000 FCFA cost per client that will keep falling.

FAQ
How long before content brings clients?
Between 3 and 6 months for the SEO blog, faster for LinkedIn and case studies. Content is a long-term investment, not an instant lever.
What publishing cadence should I keep?
Two SEO articles a month and 2 to 3 LinkedIn posts a week is a realistic, effective pace. Consistency beats occasional volume.
What makes an effective lead magnet?
A guide, template or actionable checklist exchanged for an email. Well targeted, it converts 15 to 30 % of visitors into qualified contacts.
Is content really cheaper than ads?
Over the long run yes: after 6 to 12 months, cost per lead falls 3 to 5 times below paid campaigns, because each article keeps working.
Which topics convert best?
Content that answers buying intent: "how much does it cost", "how to choose", comparisons and costed case studies attract readers close to the decision.
