Headstone Cleaning Keyword Field
A small, unusually cheap, unusually uncontested market — and almost none of it
is where a normal keyword export would tell you to look.

The size of it
31,880 searches a month, worth about $43,000 in equivalent ad spend
That is the honest number for everything a cemetery-cleaning business could
actually sell against, nationally, after collapsing Google's close-variant duplicates. The
naive version of this number — the one you get by summing a keyword export's volume column —
is 3.8× larger, and it is wrong.

Why the raw export lies
Google Ads reports one volume for a whole close-variant group and DataForSEO hands that
same number back on every member. headstone cleaning service, headstone cleaning
services, gravestone cleaning service(s), grave cleaning service,
grave marker cleaning service and tombstone cleaning service(s) all return
1,300/mo at $6.41. That is one bucket of demand, not eight — but summed naively it books
$66,664/mo of "market" from a single $8,333 reality. Across the pool that inflates the
market from $43,247 to $163,035.
The collapse rule is deliberately conservative in the other direction too:
identical volume/CPC pairs are merged only above 50/mo. Below that, 55 unrelated long-tails
all report exactly 10/mo at $0.00 — that is Google's rounding floor, not a variant group, and
merging them would under-count the tail as badly as the naive sum over-counts the head.
What survived, and what didn't
Two thirds of the discovered pool is not this market
Seeded with ten cemetery-cleaning terms, DataForSEO's keyword_ideas
endpoint returned the whole cleaning services and funeral home categories,
plus indeed (13.6M/mo) and business name generator. It associates by category,
not by topic. Relevance had to be decided on two axes, not one.

Note the inversion between the top two rows. Product/DIY carries more
raw searches than core service (49,940 vs 47,730) at less than half the CPC. People
researching D/2 Biological Solution outnumber people looking to hire — and they are
the same people, earlier. That is the content wedge, not a distraction from it.

Geography
The metros are real but thin — and city-name searches don't exist
DataForSEO Labs is country-only, so metro demand came from Google Ads

240 city-modified keywords. Zero measurable volume. All of them.
Every "headstone cleaning + city" combination across all 30 cities — headstone
cleaning seattle, grave cleaning service anaheim, monument cleaning
pasadena — returns null volume from Google Ads. Nobody types the city name for this
service. This kills the standard local-SEO play of one thin landing page per
city. Demand is expressed as near me plus the searcher's location, which
is won with a Google Business Profile and proximity, not with 30 doorway pages.

Seasonality
May is 5.5× February. Everything else is a rounding error.
Twelve months of history came down with every keyword and had not
been looked at. It turns out to be the largest single effect in this dataset —
bigger than the gap between the two metros, bigger than any cluster.
US searches per month, addressable pool, close variants
collapsed. Darker segment is service demand (T1); lighter is product/DIY (T2).
The number under each month is its index against a 100 average.

7
of 12 — demand is front-loaded
The whole year is decided in about six weeks
Demand climbs from February (index 41) through March (74) and April (112) to
a hard May spike at 224, then falls back. Memorial Day is the entire shape of
this market. A secondary ridge in August (128) tracks late-summer visiting
weather. Anything meant to rank for the May peak has to be indexed and
reviewed by March — publishing a pricing page in May is publishing it
for next year.
Why these monthly numbers were rescaled
Google's monthly_searches series does not average to the same
endpoint's own search_volume: across these 213 demand units the
monthly series runs 1.24× higher. Every other figure in
this report is built on search_volume, so the series above is
scaled to that baseline — the shape is untouched, only the units. Unscaled, the
chart would have claimed a 39,920/month average against the 31,880 quoted
earlier, from the same API on the same day.
The competition
No cleaning company owns this SERP. Google does.
Across 110 live SERPs in three geographies, the most common domains are not
competitors — they are platforms. This niche has never been properly contested.

The AI Overview problem, measured
An AI Overview fired on 77 of 111 SERPs (69%) — 68% nationally, 64% in
LA, 77% in Seattle-Tacoma. And of 440 People Also Ask answers captured,
432 were AI-generated overviews rather than a credited page. Informational
content in this niche gets summarized, not clicked. That is the strongest argument for
weighting effort toward the transactional and near-me terms, where a local pack and a
booking still stand between the searcher and the answer.
The national directory
Every dedicated cleaning operator Google Maps will show, in all 51 states
The competitor table earlier was drawn from three geographies, so
it could only ever see firms that rank nationally, in LA or in Seattle. This asked
Google Maps once per state per head term — 153 searches — and it is the only
instrument used here that returns a street address, so a firm's
state is read off its own listing rather than inferred. Monument dealers, funeral
homes, florists, cemeteries and landscapers were filtered out; what remains sells
the cleaning.

AK · DC · ID · KY · ME · MS · NE · NH · NM · OR · RI · SD returned no dedicated headstone-cleaning
operator in Maps for any of the three head terms — only monument dealers and
funeral homes. In most of the other 39, the answer is exactly one firm, usually
with a single-digit review count. This is the least contested local service
category in this study.
States = how many state-level searches the firm surfaced in, a
reach signal: 1 means a purely local business, double digits means a
service-area operator bidding for the whole country. ~
marks a firm with no published street address, where the state comes from its own
telephone area code, or failing that the state it ranks best in.
What people actually ask
120 People Also Ask questions, and one of them is the business
Harvested from the same 110 SERPs. The count is how many separate SERPs each

Fear of damage
Four of the top eleven questions are about permission
"Is it illegal…", "Can I legally…", "Do you need permission…", "Can anyone…" — 40+ SERP
appearances combined, and not one of them has a cost attached in the keyword data because
nobody is bidding on the anxiety. A page that answers the permission question plainly, by
state and by cemetery type, is the cheapest defensible asset in this entire field — and it
sits directly upstream of "how much would it cost".
The plan
Five moves, in this order
Ordered by evidence, not by convention. Each one names the finding it rests on.
One date governs all five
Demand indexes 224 in May and 41 in February, and Google needs lead time to
index, crawl and trust a new page. Everything below has to be live by
March to earn its first May. Work that slips past April is not late by
a month — it is late by a year, because the next comparable window is eleven
months out. Phase I is the exception and should start immediately: a Business
Profile accrues reviews on wall-clock time, not on publication.
I
Google Business Profile before any page
Local pack fires on 38–40% of commercial SERPs nationally and in LA. The near-me
cluster carries the highest CPC in the entire field at $3.94 average, peaking at $7.29.
Because: 240 city-modified keywords returned zero volume. Local
demand here is near me + device location, and that is a GBP ranking problem,
not a content problem. A profile with service areas, category, photos of real before/after
work and review velocity outranks any page you could write this quarter.
II
One service page per real service line — not per city
Three pages: headstone cleaning (6,600/mo head), headstone restoration
(590/mo at $2.93, services variant at $10.54), bronze & marker cleaning
(material cluster, 4,180/mo).
Because: the eight-way variant group means one page can hold
headstone / gravestone / grave marker / tombstone cleaning service(s) at once —
Google already treats them as one bucket. Writing eight pages to chase eight keywords
would split one asset into eight weak ones.
III
Publish the price
"How much would it cost to clean a headstone?" is the single most common question in
the field — 23 of 110 SERPs. The pricing cluster averages $2.51 CPC on only 440 searches
a month, meaning advertisers want it and volume is scarce.
Because: the question is being answered by an AI Overview built from
nobody's page. A real price table — by stone type, by size, by condition — is both the
highest-intent content in the field and the thing competitors are least willing to write.
IV
Own the permission question, by state
Four of the top eleven PAA questions are legal-permission anxiety, with 40+ combined
SERP appearances and no advertiser competition at all.
Because: it is upstream of the purchase and it is genuinely
jurisdictional — a page that says what Washington and California cemeteries actually
require, and what a family may do on their own plot, cannot be summarized away as easily
as a generic how-to and earns links from genealogy communities.
V
Take the D/2 cluster seriously, as acquisition
49,940 searches a month across 89 product keywords — more raw volume than the entire
core service cluster. d2 biological solution alone is 2,900/mo.
Because: these are the same customers one step earlier, and their
questions ("Can I use Dawn?", "What should you not clean granite with?", "How to clean a
100 year old headstone?") are exactly the ones where a wrong answer damages the stone.
Being the honest technical authority on the DIY path is how a service business earns the
job when the DIY path fails — which is the field's most common purchase trigger.
What this does not establish
Limits
No client, no domain. This survey was run without a target site, so
there is no ranked-keyword baseline, no backlink profile, and no gap analysis against a
specific competitor. Pointing it at a domain adds ranked_keywords and
competitors_domain for about $0.25.
Volume is Google's estimate, not observed traffic. Search volumes are
12-month averages from Google Ads, rounded hard at the low end — the 10/mo floor covers
anything from 1 to 49.
The value column is a proxy. Volume × CPC is what the clicks
would cost to buy, not revenue. It ranks opportunities; it does not forecast a P&L.
15 cities per metro, not every city. Bothell, Lynnwood and Shoreline
all returned demand once measured; the tail of smaller suburbs is unpriced.
The directory is what Maps shows, not a business registry. A firm
with no Google Business Profile does not exist to this method, and three head terms at
20 results per state is a wide net but not an exhaustive one. Read "12 states with no
operator" as "nobody is visible there", which is the thing that matters commercially,
not as proof that nobody is trading.
21 of 77 operators have no published street address. Their state
comes from the firm's own telephone area code, which is good evidence but not proof —
a business can keep a number after moving. Two firms had neither address nor a
geographic area code and are placed by where they rank best.
Seasonality is national and category-wide. The monthly shape is
summed across the whole addressable pool; individual keywords will have their own
curves, and the two metros were not broken out separately.
