A genuine ranking decline, where positions have measurably fallen for queries you previously held, has a smaller set of causes than most people assume. Working through them in order of likelihood resolves most cases without guesswork.
First confirm it is actually rankings that fell rather than traffic. Those are different problems: see why organic traffic dropped for the distinction.
The causes, in order of frequency
1. Something changed on your site
Far more declines are self-inflicted than are caused by anything external, and this is the cheapest category to check.
- Content shortened or rewritten during a redesign, removing what earned the ranking.
- URL changes without redirects, or redirects pointing somewhere unhelpful.
- Internal links removed when navigation was rebuilt.
- A canonical or noindex change affecting the page.
- Page speed regression on the affected template.
Check your deployment log for the decline window before considering any external explanation.
2. Your own pages now compete
Publishing a new page targeting the same query splits the signal. Search Console will show more than one of your URLs receiving impressions for it, and the ranking URL may alternate. See keyword cannibalisation.
3. Competitors improved
The least satisfying cause and a common one. Your page is unchanged and something better now exists. Compare your page against what replaced you and name the difference specifically.
4. The result set changed shape
Search results evolve in what they reward. Where the results for a query have shifted from commercial pages to guides, a commercial page will fall regardless of quality. This is an intent mismatch and it requires a different page, not a better one.
5. An algorithm update
Real, but blamed far more often than it applies. Test it before accepting it: update impacts begin within a day or two of rollout and are usually broad rather than confined to one template. See algorithm update recovery.
6. Links lost
Referring pages removed, redirected or de-indexed. Slower and more gradual than the others, and worth checking where the decline was steady rather than sudden.
What to do first
- Confirm the page is still indexed and self-canonical.
- Check what changed on your site in the window.
- Check whether another of your pages is now receiving impressions for the query.
- Look at what ranks in your place and name what it does better.
- Only then decide whether the page needs improving, consolidating or retargeting.
What not to do
- Do not rewrite the page immediately. If the cause is cannibalisation or a directive, rewriting achieves nothing.
- Do not change many things at once, which destroys attribution.
- Do not assume an update because the timing roughly fits.
- Do not disavow links reflexively. It is rarely the cause and can do harm.
Frequently asked questions
How much ranking movement is normal?
Positions fluctuate by a place or two routinely, and more on competitive terms. A sustained fall of several positions, or a drop off the first page, is worth investigating. Daily movement usually is not.
Can rankings recover on their own?
Sometimes, particularly after volatility around an update. If the cause is a real change on your site or a genuinely stronger competitor, waiting does not fix it.
One page dropped and the rest are fine. What does that mean?
Almost certainly page-level: a change to that page, a competing page of your own, or a stronger competitor for that query. Sitewide explanations do not fit a single-page decline.
Should we build links to recover?
Only if the diagnosis points at authority. Building links to fix a cannibalisation or intent problem spends money on the wrong cause.
