Maintenance and common mistakes
Nothing you built in the previous thirteen modules stays built. Not because Google is capricious, but because sites change, links rot and competitors keep working.
What this actually costs you
- Hours to learn
- 3
- Hours / month
- 4 to 6
- Tools
- $0 to $139/mo
- Difficulty
- Low, if you actually do it
What this looks like when it is done badly. Nothing is checked for fourteen months. Then traffic drops, and the investigation finds a theme update that removed the canonical tags in March, forty broken internal links from a page that was renamed in June, and a services page still advertising 2025 pricing. Each one was a five-minute fix on the day it happened.
Hours and tool costs are RedSEO’s own estimates from client work and from teaching this material, not industry survey data. They assume a business owner doing the work themselves on a site under about 50 pages.
Nothing you built in the previous thirteen modules stays built. Not because Google is capricious, but for reasons that are almost boringly mechanical: sites change, links rot, plugins update, staff leave, and competitors keep working while you stop.
The three things that actually decay
Your content becomes untrue. Prices change, services change, the year in your headline stops being this year. This is the fastest and least technical decay and it does the most direct damage, because a reader who catches one wrong fact discounts the rest of the page.
Your technical setup drifts. A theme update changes a template. A plugin starts generating tag archives. A page gets renamed and forty internal links point at nothing. Nobody did anything wrong; the site simply moved underneath you.
Your competitors improve. This is the one people take personally and should not. Position four with no change on your side means somebody else did the work. It is information, not an insult.
The calendar
There is no maintenance calendar generator here yet, so here it is as a table you can copy.
| Cadence | What you check | Roughly |
|---|---|---|
| Monthly | Page Indexing report, your five numbers, reviews and listings | 30 to 45 minutes |
| Quarterly | Decaying pages, a fresh crawl against your baseline, top pages still true | 2 to 3 hours |
| Annually | Prune what never earned, re-run the payback math with real numbers | Half a day |
Refreshing beats publishing, again
The single highest-return maintenance task is finding pages whose impressions are falling and improving them. They already have history and internal links. They are close.
Sort your Search Console pages by impressions, compare against the same period last year, and look at what dropped. That list is worth more than any list of new topics, and it takes ten minutes to produce.
One thing to avoid, because it is a common shortcut: Google warns against changing “the date of pages to make them seem fresh when the content has not substantially changed.” Restamping a date is not a refresh.
Have us run the monthly checks
The mistakes that quietly undo a year
In rough order of how often I find them:
A redesign shipped without a redirect map. The single most destructive thing on this list. Every URL changes, nothing is mapped, and a year of accumulated authority is thrown away in an afternoon by people who thought they were improving the site.
A staging setting reaching production. A noindex or aDisallow that was correct on the test site and catastrophic on the live one. Module 7 covers the check; this module is about doing it monthly.
Publishing a second page for a term you already rank for. Cannibalisation, created slowly, usually by someone who did not know the first page existed. This is why the keyword map from module 4 has to be maintained rather than written once.
Letting listings drift. A phone number changes on the website and nowhere else. Module 10.
Reacting to a single bad month. Panic-rewriting pages that were working, in a month that always dips, is a self-inflicted wound. This is what module 13 exists to prevent.
What I would do in your position
Put a recurring 45 minutes in the calendar for the first working day of each month, and do the monthly column. That is the whole recommendation.
Add the quarterly review as a recurring half-day four times a year. If you do those two things and nothing else from this module, your site will stay in better shape than most, because the baseline you are being compared against is a competitor who checks nothing until something breaks.
Build your own calendar
The generator sizes the schedule to your site and exports it as a calendar file, so the recurrence handles itself instead of depending on you remembering.
Generate your schedule
Five questions, then a monthly, quarterly and annual plan sized to your site, with the annual hours totalled so you can see the real commitment before you agree to it.

Quarterly re-audit
Same tool as module 2. What matters is the difference from last quarter, not the score.
The recurring calendar
Three cadences. If you only ever do the monthly column, you will still be ahead of most sites, because most sites do none of it.
Monthly: read the Page Indexing report
Look for new exclusions rather than the total. A category appearing that was not there last month is the earliest warning you get of a technical change nobody told you about.
Monthly: record your five numbers
Module 13. Same day, same window, one sentence on what you shipped. Fifteen minutes.
Monthly: reply to every new review and check your listings
Module 10. This is the part that decays fastest because it depends on a habit rather than a system.
Quarterly: find your decaying pages
Pages that used to earn impressions and now earn fewer. That list is your refresh queue and it is more valuable than any list of new topics.
Quarterly: re-run a crawl and compare against your baseline
New broken links, new redirect chains, titles a plugin rewrote. Sites accumulate these silently through ordinary use.
Quarterly: check your top pages still say true things
Prices, hours, staff, services, claims about the year. Nothing damages trust faster than a confidently outdated page, and this is the check nobody schedules.
Annually: prune or merge what has never earned anything
A page with no impressions after a year is not waiting to succeed. Merge it into something better and redirect it, or remove it.
Annually: re-run module 1 with your real numbers
You now have actual conversion values and actual lift instead of estimates. Re-running the payback math with real inputs is the most honest annual review available to you.
Can you do this yourself?
You can do this yourself if
- You can hold a recurring fifteen minutes a month. That alone puts you ahead of most sites, which do nothing until something breaks.
- You are willing to delete pages. Pruning is the part people refuse to do because publishing felt like work and removing feels like waste.
- You built the thing yourself, so you know where the moving parts are and what you changed.
You cannot do this yourself if
- You are the bottleneck, which after thirteen modules you now know for certain. Maintenance is small and constant, and small constant tasks are the first thing to lose to a busy quarter.
- Your site changes faster than you can check it, because other people publish to it or a platform updates itself.
- A drop has already happened and you cannot tell whether it was an algorithm update, a technical change, seasonality or a competitor. Untangling that after the fact needs history you may not have kept.
Questions people ask about this
- What does SEO maintenance actually involve?
- Three cadences. Monthly: the Page Indexing report, your five numbers, reviews and listings, around 30 to 45 minutes. Quarterly: decaying pages, a fresh crawl against your baseline, and checking your top pages still say true things. Annually: prune what never earned anything and re-run the payback math with real numbers.
- How often should I update my website for SEO?
- Content should be updated when it stops being true, which is a different trigger from a schedule. The recurring work is checking: monthly for indexing and metrics, quarterly for decay and technical drift. Publishing on a schedule is module 6; this is about not letting what exists rot.
- What are the most common SEO mistakes?
- A redesign shipped without a redirect map is the most destructive and the most common. Then a staging noindex or robots Disallow reaching production, publishing a second page for a term you already rank for, letting local listings drift out of sync, and reacting to a single bad month by rewriting pages that were working.
- Should I delete old blog posts?
- Merge or remove pages that have earned nothing after a year. They are not waiting to succeed, and they dilute your coverage of the topic. Merging into a stronger piece and redirecting is usually better than deleting outright, because it keeps whatever signals the old URL had.
- Does updating the publish date help?
- No. Google explicitly warns against changing "the date of pages to make them seem fresh when the content has not substantially changed". A refresh means the content genuinely improved; restamping the date is the shortcut Google names.
- Why did my rankings drop when I changed nothing?
- Usually one of three things: a competitor improved, a technical change happened underneath you through a theme or plugin update, or it is seasonality. The order to check is technical first because it is binary and fast, then seasonality against last year, then the results page itself to see who moved.
