The work that never shows up in case studies
When a project climbs from position 15 to position 3, there’s celebration. Charts get shared on LinkedIn, emails go out to the client, the portfolio gets updated.
But there’s another kind of SEO nobody celebrates: the kind that keeps you from dropping.
Keeping a positive gap versus the previous year when the whole sector is falling. Getting ahead of seasonal effects before they hit. Stabilizing a site coming out of a penalty. That work exists, takes up 80% of the time, requires more expertise than “growth strategies”, and almost never appears in a case study.
Why maintenance is invisible
The problem is structural. If you do your maintenance work well, nothing visible happens. Traffic holds, rankings don’t drop, the site keeps working. Nobody thanks you for something that didn’t happen.
But if you stop doing it:
- Competitors overtake you
- Content goes stale
- Broken links pile up
- Technical errors grow
- The drop comes, just delayed
What I do every month (and nobody asks about)
1. Monitoring key rankings
Not all keywords matter equally. I keep a set of 20-30 critical terms per project that I monitor weekly. If one drops more than 3 positions, I investigate before it becomes a trend.
2. Technical error audit
Search Console keeps generating new errors:
- Pages that stop existing
- Redirects that break
- Indexing problems
- Core Web Vitals errors
Once a month, I clean up. It isn’t glamorous, but every ignored error is a small authority leak.
3. Updating evergreen content
Content that worked 18 months ago may now be out of date. I check:
- Is the data still correct?
- Have best practices changed?
- Are there new competitors in the SERP?
- Has search intent evolved?
Sometimes updating an existing article gets better results than writing a new one.
4. Backlink control
Toxic links show up on their own. Scraping, spam directories, negative SEO attacks… every quarter I review the link profile and disavow whatever is doing harm.
5. Competitor analysis
Not to copy, but to anticipate. If a competitor is publishing content in an area where we aren’t present, that’s a signal. If they’re earning links from a type of source we hadn’t considered, that’s an opportunity.
The case of the “stable” site
A client once told me: “Traffic has been flat for 6 months. Do we really need to keep doing SEO?”
I showed them what I had done in those 6 months:
- Fixed 34 404 errors that had appeared after a CMS update
- Merged 8 articles that were cannibalizing each other
- Created 3 content hubs to improve internal linking
- Updated 15 articles with 2024 data that had become outdated
- Optimized titles and metas on 12 pages that were losing CTR
Without that work, the 6 months of “stability” would have been 6 months of gradual decline. Traffic held because someone was working to keep it there.
Maintenance SEO doesn’t make headlines, but it protects what you already have.
Signs you’re neglecting maintenance
| Warning sign | Where to check it | Critical threshold |
|---|---|---|
| Growing coverage errors | Search Console → Indexing | +10% per month |
| Pages losing positions | Sistrix/Ahrefs → Tracking | -3 positions/month |
| Content not updated | CMS → Last modified date | >24 months |
| Backlinks not reviewed | Ahrefs → Link profile | >6 months |
| Core Web Vitals getting worse | PageSpeed/GSC | Outside “Good” |
| Falling CTR | Search Console → Performance | -20% vs. previous quarter |
| Orphan pages | Screaming Frog → Architecture | >5% of total |
If three or more signs are red, you have accumulated technical debt that is going to take its toll.
How I structure the invisible work
I have a quarterly system that I follow religiously:
| Frequency | Task | Tool | Estimated time |
|---|---|---|---|
| Weekly | Critical keyword rankings | Sistrix/Ahrefs | 15 min |
| Weekly | New errors in GSC | Search Console | 10 min |
| Weekly | Brand mentions | Google Alerts | 5 min |
| Monthly | Basic technical audit | Screaming Frog | 1-2h |
| Monthly | Worst-performing content | GA4 + GSC | 1h |
| Monthly | Competitor analysis | Semrush/Ahrefs | 30 min |
| Quarterly | Backlink audit | Ahrefs/Majestic | 2-3h |
| Quarterly | Evergreen update | Manual | 4-6h |
| Quarterly | Orphan URL cleanup | Screaming Frog | 1-2h |
| Yearly | In-depth technical audit | Multiple | 1 day |
| Yearly | Architecture review | Manual | 4h |
| Yearly | Full keyword research | Semrush + manual | 1 day |
This system takes roughly 4-6 hours a week per project. It sounds like a lot, but it’s the difference between holding rankings and gradually losing them.
The ROI of maintenance
It’s hard to calculate because you’re measuring something that didn’t happen. But think of it this way:
| Scenario | Monthly traffic | Estimated value | Cost of a 20% drop |
|---|---|---|---|
| Mid-size ecommerce | 50K sessions | €50,000 | €10,000/month |
| Large ecommerce | 200K sessions | €200,000 | €40,000/month |
| B2B SaaS | 20K sessions | €100,000 | €20,000/month |
| Content portal | 500K sessions | €25,000 (ads) | €5,000/month |
If SEO maintenance costs €2,000/month and prevents a drop that would cost €20,000/month… the ROI is 10x. But nobody sees it that way because the drop “didn’t happen”.
Maintenance SEO is insurance. You don’t appreciate it until you need it, and by the time you need it, it’s too late.
Why agencies don’t sell it
Selling “maintenance” is hard. There are no spectacular charts, no sexy pitch for the sales team.
It’s easier to sell “we’re going to grow your traffic by 50%” than “we’re going to make sure you don’t drop”. But the second is just as important, maybe more, because a drop can wipe out years of work in weeks.
The professional SEO mindset
The best SEOs I know spend more time on maintenance than on “growth strategies”. They understand that:
- Small continuous adjustments beat big one-off actions
- Preventing is more efficient than recovering
- Consistency beats intensity
- A site that holds steady while the competition drops is rising in relative terms
Google explains it in its guide for site owners: SEO is an ongoing process, not a one-off project. Doing SEO isn’t just about going up. It’s also about not going down.
