How we score electricians in Spartanburg, SC

What this page covers

The Spartanburg, SC Electrician Guide currently scores 44 electrician businesses operating in and around Spartanburg. This page explains exactly how that score is built, why we weight it the way we do, and where the honest limits of the method sit. Nothing here is guesswork on your part: the same rubric runs against every business in the guide, every time we refresh the data.

The five signals, heaviest first

Each business gets a composite score from 0 to 100, built from five measured signals. Here they are in order of weight:

• Sentiment, 28%. A synthesis of what recent reviews actually say, praise and complaints alike, not just how many stars were left.
• Rating, 26%. The business's aggregate Google star rating.
• Volume, 20%. How many reviews exist, log-scaled so that five reviews don't carry the same weight as five hundred.
• Recency, 12%. How recently customers have actually left reviews.
• Completeness, 14%. Whether basic listing information (phone number, website, hours, address) is present and accurate.

Why sentiment carries the most weight

Star averages flatten everything into one number, and that number can hide a real pattern. Two electricians can both sit at 4.5 stars, but one of them might have a string of recent reviews mentioning the same issue: no-shows, jobs left unfinished, quotes that doubled on arrival. The star average won't tell you that. Reading what people actually wrote will. That's why sentiment, our synthesis of recent review themes, is weighted higher than the rating itself. It's the closest thing to catching a real problem before it becomes your problem.

Why the other signals matter

Rating still matters because it's the broadest snapshot of how customers felt overall, and it's what most people check first. Volume matters because a handful of five-star reviews from friends and family looks very different from hundreds of reviews accumulated across years of real jobs, which is why we log-scale it rather than let raw review counts dominate. Recency matters because an electrician who was excellent five years ago under different ownership or staff may not be the same business today. Completeness matters in a practical way: if a listing is missing a working phone number, hours, or an address, that's friction you'll hit the moment you try to actually hire someone, regardless of how good the reviews are.

Where the confidence runs low

Some of the 44 businesses in this guide have very few recent reviews. When that's the case, the resulting score is less reliable, because a single bad or good review can swing it disproportionately. We label those listings as low-confidence rather than let them sit silently alongside businesses with a deep, current review history. We also don't republish review text wholesale. What you'll see is our synthesis of the themes running through recent reviews, with a link out to Google so you can read the original source yourself and form your own judgment.

Scores are not for sale

Scores come from this rubric and this data, full stop. They are never adjusted by hand and never edited to favor a business. Paid placement exists in some parts of this guide, and where it does, it is always labelled clearly as paid. It never changes a business's score. Separately, if any best-of list on this site involved editorial judgment in choosing or ordering picks, that involvement is disclosed on the list itself, such as our best residential electricians in Spartanburg roundup.

Who's behind this

Amara Okafor, Editorial Lead, maintains the rankings for this guide. Amara oversees how the rubric is applied and reviewed as new data comes in, so the scoring stays consistent across all 44 listings rather than drifting business by business.
