Local Search Competition Index
66.4/ 100
Rank 346 of 1,822 counties with 20,000+ residents and 155 of the 400 markets we cover. More local businesses chasing the same searches pushes the score up. How we calculate it
We score every U.S. county-equivalent with 20,000 or more residents on how many local-search businesses (including the lawyers, dentists, contractors, restaurants, salons and agents that customers find on Google and the map) compete for its residents. New Castle County scores 66.4, which is more contested than most.

| Wilmington | 71,675 | 12% |
| Newark | 30,169 | 5% |

Market profile
New Castle County's Competitors Are Bigger Than Average
New Castle County has fewer very small businesses than most counties: only 52.3% of its 3,139 local-search employer locations have fewer than five employees, below 82% of counties. Larger operations generally have someone looking after their website and reviews, so ranking here takes consistent output, not just a one-time site build.
New Castle County has 578,592 residents, which ranks 120th of 3,143 U.S. counties, and the headcount has shifted +1.4% since the 2020 Census. Across all industries it has 17,672 employer locations, 30.5 per 1,000 residents.
No single place dominates New Castle County: the largest, Wilmington, has about 12% of residents, and others include Newark (30,169), Middletown (25,022), Elsmere (6,157) and New Castle (5,549). Searchers use their own town's name, so each place is its own ranking opportunity.
75% of residents (431,846 people) live outside any incorporated place, so county-level and "near me" searches matter as much as city names.
Who else is in the results
Which New Castle County Categories Are Most Contested in Local Search
Each local-search category's employer locations are divided by population and compared with the median county. Read 2.0x as double the businesses per resident of a typical county.

Crowding = employer locations per 10,000 residents divided by the median U.S. county of 20,000+ residents (1.0x is typical; the dark tick marks it). Figures are establishments from the Census County Business Patterns (2017, 2022), not search volumes. How we calculate this
The law offices category is the most contested in New Castle County: 340 locations, 2.0x the density of a typical county, and down 1.4% since 2017. Janitorial services (164 locations, 1.9x) and beauty salons (162 locations, 1.8x) also run above a normal county. The general automotive repair category is the least contested here at 0.9x typical (141 locations), so there are fewer rival pages for those searches.
Residential remodelers grew fastest, up 30.1% since 2017 to 272 locations, so new rivals keep arriving there. Physicians offices went the other way, down 20.6% to 300 locations. The tiniest competitors are in real estate agents and brokers: 199 of 227 locations (88%) have fewer than five employees.
Keep this in mind: this counts businesses, not searches. We have no search volumes or traffic for any keyword, and we do not claim any; crowding shows that more sites compete, not what results will be.

Housing demand
New Castle County Housing Permits Since 2021: Down From the High, Turning Up This Year
New housing units authorized by building permits. Data: U.S. Census Bureau Building Permits Survey (county annual files, and the year-to-date bars compare the same months each year). Permits count homes approved to be built, not homes completed.
New Castle County authorized 1,822 housing units in 2021 and 1,318 in 2025, about 28% fewer; 2025 still works out to 22.8 units per 10,000 residents, less than in 58% of counties. For January through August, permits are running at 1,011 against 879 a year earlier (+15%).
The construction-linked categories already most contested in New Castle County are real estate agents and brokers (1.6x typical) and residential remodelers (1.6x typical). Because SEO builds gradually, the best time to start is before demand arrives; pages that are already indexed and ranking meet new households first.

How long does SEO take to work in New Castle County?
SEO builds over time and no one can promise a date. The speed of the climb depends on how contested your category is, how strong your website and Google Business Profile are, and how much we can build. In New Castle County, law offices is especially contested (2.0x a typical county), so expect that category to take longer. We work in six-month planning cycles, with no contract, and report each month.
Is New Castle County a competitive market for SEO?
The densest category here is
More than most. New Castle County scores 66.4 on our Local Search Competition Index, ranking 346th of 1,822 counties with 20,000+ residents and 155th of the 400 markets we cover. Law offices, at 2.0 times the typical county. That makes city-and-service pages and strong reviews more important, not less.
Which local businesses compete for search in New Castle County?
Across the fifteen categories we track, the largest by employer locations in New Castle County are full-service restaurants (439), law offices (340) and physicians offices (300). Measured against a typical county, the most contested are law offices (2.0x) and janitorial services (1.9x). A large or crowded category does not settle whether SEO will work for you; it shows how many other sites you would be sharing the results with.
Which cities in New Castle County would you build pages for?
Whichever you serve. New Castle County has 6 places of 2,500 or more residents, led by Wilmington, Newark, Middletown, Elsmere and New Castle. RankGuarantee™ builds local landing pages for each service in each city you serve (25 new pages a month on the $495 plan, 25 to 100 on Organic Growth), so the plan follows your service area, not the county line.
Do you handle local SEO and Google Maps rankings?
Yes. Every Organic Growth plan includes Google Business Profile optimization, citations and review management, plus on-page and technical SEO, strategic content and AI search (GEO) work. Map results matter most for searches such as "near me", and most of the local categories in New Castle County rely on them.
Can SEO get my business mentioned by ChatGPT and Google's AI?
It may. AI search (GEO) optimization is part of our plans: well-structured pages and consistent business details give AI tools more to work with. Nobody can guarantee an AI mention, and we do not promise one, but the work behind rankings is also the content those tools draw from.
Do I need SEO, Google Ads, or both in New Castle County?
Often both. Google Ads can send calls within days and costs per click; SEO builds more slowly and then works without paying per click. If you need leads now, start with ads (we manage Google Ads, Bing and Meta too) and build SEO as the asset that makes you less dependent on ads.
Am I locked into a contract, and what do I get each month?
There is no setup fee, and you can cancel anytime. Your plan covers the keyword research, website audit and six-month strategy at the start, then the pages and content in your tier, rank tracking, and a single account manager familiar with your New Castle County business.
