Sentinel Electric — Competitive Analysis
Commercial and Residential Electrical Contractor | Chicago, IL | Est. 1999 (27+ years)
Overall Visibility Score
4 / 70
Sentinel Electric has been operating successfully for 27+ years with strong commercial relationships. The digital presence simply has not kept pace with the business.
CRITICAL DISCOVERY: Two Duplicate Google Business Profiles
Sentinel has two separate Google Business Profiles — both with 0 reviews, neither with a website linked, and one categorized as “Construction company” (wrong). Google penalizes businesses with duplicate listings. This must be resolved before any other optimization work can begin.
| GBP #1 | GBP #2 | |
|---|---|---|
| Name | “Sentinel electric” (lowercase e) | “Sentinel Electric inc” |
| Category | Construction company (WRONG) | Electrical installation service |
| Hours | Open – Closes 4 PM | Not set |
| Website | Not linked | Not linked |
| Reviews | 0 | 0 |

Google Maps Visibility Scans
Both Sentinel Electric GBP listings are 100% invisible for “electrician near me” across the entire Chicago market. Not a single grid point registered a ranking — both profiles show an average rank of 20+. There are 722-724 competing electricians detected in the Chicago grid.
Revenue impact: For an electrician in Chicago, the Google Map Pack drives an estimated 40-60% of inbound leads. At 100% invisible, Sentinel is missing every single one — likely tens of thousands of dollars per month in lost opportunity.
GBP #1: “Sentinel electric” (Construction company)
GBP #2: “Sentinel Electric inc” (Electrical installation service)
The 3 Critical Gaps
Gap #1: Duplicate GBP Listings Are Actively Hurting Rankings
Two GBP profiles with different names and different categories are splitting Google’s trust signals and creating confusion. Google penalizes businesses with duplicate listings. Neither profile has a website linked, hours are inconsistent, and neither has a single review. This needs to be consolidated into ONE optimized profile immediately.
Business Impact: Duplicate GBPs can trigger Google suspensions and guarantee poor map rankings. This is likely the #1 reason for total invisibility — fix this before anything else.
Gap #2: Wrong Primary Category on GBP #1
GBP #1 is categorized as “Construction company.” Google will never show a “Construction company” when someone searches “electrician near me” or “electrical contractor Chicago.” The ideal primary category is “Electrician” or “Electrical contractor” depending on focus.
Business Impact: Wrong category = excluded from relevant searches entirely. Even if everything else were perfect, this category mismatch alone would prevent map visibility.
Gap #3: Zero Service Pages vs. Competitors with 24-26 Each
CM Electric has 26 individual service pages. Current Electrical has 24. Sentinel has 0 — all services are listed in a single block on the homepage. The Specialties page returns a 404 error.
Business Impact: Every service keyword in the Chicago electrical market is uncontested by Sentinel.

3 Quick Wins — Things You Can Do This Week
| Quick Win #1: Consolidate to ONE GBP and Fix the Category Delete or merge the duplicate listing. Set the surviving profile’s primary category to “Electrician” (or “Electrical contractor” if commercial is the focus). Add “Electrical installation service” and “Commercial electrician” as secondary categories. Link the website. Set consistent hours. This is the single highest-impact action — nothing else matters until this is fixed. |
| Quick Win #2: Launch a Review Generation Campaign With 27 years of commercial relationships and a client list that includes developers and construction firms, there is a deep well of past partners and clients to tap. Target 15-20 reviews in the first 90 days. Even 10 reviews would put Sentinel ahead of the baseline for a new GBP. |
| Quick Win #3: Fix the 404 Errors and Add Meta Descriptions The About page and Specialties page are broken (404 errors). The homepage title tag is just “Sentinel Electric” with no keywords or location. Zero meta descriptions exist anywhere on the site. Fix the broken links, add “Chicago Electrical Contractor” to title tags, and write meta descriptions for every page. This is a 2-hour fix. |
