The "always more" illusion
Most SMEs think growing SEO traffic means publishing more articles. False. A Backlinko study (2023, refreshed 2025) on 1,800 sites shows that enriching an existing article with +30% content generates on average +30 to +100% traffic on that article.
In other words: reviving your old articles is statistically the best ROI you can get in SEO. And nobody does it, because it's less rewarding than publishing new stuff.
The Saint-Louis restaurant case
A restaurant in Saint-Louis called us in November 2025. Blog created 2019, 64 articles published, traffic stable at 1,200 visits/month for 2 years. The owner thought he needed 30 new articles. We proposed otherwise: publish nothing new for 3 months, refresh 30 existing articles.
Strong initial resistance. We insisted. Client accepted the test.
3 months later: 1,200 to 3,800 visits/month. Tripled traffic without a single new article.
How we proceeded
Step 1 — Refresh candidate identification. We extract via Google Search Console articles that:
- Already have traffic (at least 30 visits/month)
- Rank between position 8 and 25 (close to top 5)
- Haven't been updated in 18+ months
Out of 64 articles, 31 fit the criteria. We selected 30.
Step 2 — Individual audit. For each article we identify:
- Keywords lost since publication (via Ahrefs)
- New sub-questions users ask (AnswerThePublic + "People Also Ask" on Google)
- Outdated info (2019 prices vs 2026 for example)
- Missing internal links
Step 3 — Surgical rewrite. We don't rewrite everything. We add:
- A "Updated May 2026" callout at article start
- 1-2 new sections answering PAA
- A 4-6 question FAQ
- A table when relevant
- 3-5 new internal links
- Updated numbers, prices, sources
Article goes on average from 800 to 1,400 words (+75%).
Step 4 — Clean republish. Keep the same URL (critical to preserve accumulated authority), update the "modified on" date, submit URL to GSC for reindexing.
The real budget
| Item | FCFA budget |
|---|---|
| 30 articles audit | 180,000 |
| Refresh 30 articles x 35,000 | 1,050,000 |
| Tools (Ahrefs, AnswerThePublic) | 120,000 |
| GSC resubmission + monitoring | 50,000 |
| Total | 1,400,000 |
Compared to the cost of writing 30 new articles: 30 x 80,000 = 2,400,000 FCFA, for a statistically inferior outcome.

Ideal refresh calendar
| Article type | Refresh frequency |
|---|---|
| Practical guide | Every 12 months |

| Evergreen "how to" | Every 18-24 months |
| Regulatory article (tax, legal) | At each law change |
The 3 mistakes that kill a refresh
- Changing the URL — instant authority loss. Always keep the original URL.
- Cosmetic refresh — just changing the date without adding value isn't enough. Google detects it.
- Too-frequent refresh — leave at least 6 months between refreshes, otherwise it looks like manipulation.
FAQ
How many articles to refresh per month?
8 to 12 articles is a sustainable pace for an SME. More is dilution.
What about articles with 0 visits in 2 years?
Either transform them (topic change), 301-redirect to a similar article, or noindex. Never let them rot.
Can we refresh an article published 6 months ago?
Generally too early. Wait 12 months minimum unless info became false.
Can AI do the refresh for us?
For the draft yes, for the final version no. Unedited AI content is detectable and downranked by Google since March 2024.
