DPF cleaning is the biggest job search in the garage trade. Here is the page that wins it, legally
33,100 UK searches a month for DPF cleaning, 3,600 for regeneration, 1,900 for a delete you must never sell. What a garage's DPF page must say to win them.

"DPF cleaning" is searched about 33,100 times a month in the UK, more than any other single job a general garage does, with "DPF regeneration" at 3,600 behind it. Those are Google's own figures from Keyword Planner for the twelve months to August 2026. The searches rise from October, when short cold trips stop filters burning off their soot and the warning lights come on. Most garages that do the work have no page for it, or a page that says "DPF cleaning available, call for details", which answers none of the questions the driver typed. The page that wins is the one that explains the three fixes, says which the driver probably needs, and draws the legal line on deletes before anyone asks.
Why the searches spike from October
A diesel particulate filter cleans itself by burning the soot off at motorway temperature. A car that does school runs and supermarket trips never gets there, so the soot builds, the light comes on, and in a few weeks the car goes into limp mode. That happens most in the months when engines take longest to warm, and the searches follow: a driver with an amber light and a car that will not pull above 40 is searching on the hard shoulder, not planning ahead. The garage whose page is ready in September gets the October driver.
What the driver is actually asking
Behind "DPF cleaning" sit a handful of real questions, and the page has to answer them in the driver's order, not the garage's.
- Can I drive with the DPF light on, and for how long?
- Is it blocked, or is something else making it block? The driver has usually been told "it's the DPF" by someone who did not check.
- Clean, forced regeneration or replace: what is the difference, which do I need, and which is the garage going to try to sell me?
- How long will the car be off the road?
- Will it just happen again?
The DPF page: what it must say
- What the filter does and why it blocks, in two sentences a driver can repeat.
- The three fixes, each with when it applies: a forced regeneration for a filter that is full of soot but sound; a proper clean for one that regeneration cannot clear; a replacement for one that is cracked or full of ash. Say which you do in house.
- The diagnostic step first, in writing: a blocked filter is often a symptom of a lazy EGR valve, a failed sensor, a boost leak or the wrong oil, and cleaning the filter without finding the cause means the driver is back in six weeks. A page that says this reads as a garage that has done the job a hundred times.
- The legal line, plainly: removing or disabling a DPF is an MOT failure and an offence on the road, and you do not do it. Drivers search for deletes; the ones you want are reassured, and the ones you do not want go elsewhere.
- Whether the car needs to come to you, and the time it takes.
- What happens if the filter cannot be saved, and whether you fit new or reconditioned.
- Real photographs of the job and the kit, not a stock image of a clean exhaust.
- The booking path: the phone number, a form, and the reassurance that a conversation comes before a price.
That page is not a town page. One DPF page for the garage, written once and properly, with the towns you serve named in a sentence, beats a copy for every town, which Google reads as one page repeated and files under "crawled, currently not indexed". We have the before-and-after numbers for exactly that mistake on the results page.
The searches never to chase
"AdBlue delete" is searched 1,900 times a month and "DPF delete" sits in the same family. Do not write for them, do not bid on them, and do not let a page imply you might. Google will not run adverts for emissions defeat and a page that sells the work is evidence against the garage. Write the legal line on the DPF page instead and let the searches for a delete find a page that explains why the answer is no and what the lawful fix is. Some of those drivers book the clean.
Clicks, adverts and the long game
The DPF searches are among the most expensive a garage can advertise on, and the measured bid ranges are on our Google Ads page. A page that ranks for them organically earns the same click for nothing, month after month, which is the whole argument for writing it properly once. A mobile tuning business near Mold whose DPF and AdBlue pages we rewrote in August now holds page one for its North Wales DPF and AdBlue searches, at positions 12.7 and 8.2 in the latest 28 days, from pages that did not rank at all before; the full figures are in the KP Tuning case. Expect a new DPF page to take three months to settle on a garage domain that has not published anything specific before, and faster on one that already earns.
The driver searching "DPF cleaning" has a light on and a car that will not pull. The page that tells them what is wrong, what it costs in time, and that you will find the cause rather than clean the symptom, is the one they ring from the lay-by.
If your garage does DPF work and has no page for it, or has one that says nothing, that is the first page we would write, and the audit will say so. The order of work for a garage that wants the expensive jobs, not just the MOTs, is on the SEO for garages page.
Questions on this topic
Can I mention DPF delete on my site if I do not do it?
Yes, as the thing you refuse: one clear sentence that removal is an MOT failure and an offence on the road, and that you clean, regenerate or replace instead. That sentence protects you and reassures the right driver. A page written to attract the delete search is a different thing and we will not write one.
Should the DPF page carry a price?
If you can give an honest from-price for a diagnostic or a clean, yes, because the driver is comparing and the assistants that answer price questions quote only businesses that publish one. If every job is different, say what decides the price instead of leaving the question unanswered.
Regeneration or cleaning: which word should the page use?
Both, correctly. Drivers search "cleaning" nine times more often than "regeneration", so the page title carries cleaning; the body explains that a forced regeneration is one of the fixes and when it applies. A page that uses the two words as synonyms reads as a garage that does not know the difference.
Is one DPF page enough, or one per town?
One, written properly, with the towns you cover in a sentence. Copies with the town name swapped are the commonest fault on garage sites and Google stops indexing them. The case study on the results page has the numbers.
How long before a new DPF page ranks?
Plan for three months on a domain that has never published anything specific, less on one that already earns. The page starts collecting impressions within weeks; the clicks follow as it is shown and chosen. Nothing is judged before it is four weeks old.
