Central Penn's Top Construction Websites

Every year, Central Penn Business Journal publishes its Book of Lists, a directory of the top companies throughout central Pennsylvania.

These lists show the "who's who" of various industries in terms of size and revenue. But as a Lancaster marketing agency we're always interested in what top local business are doing with their website design and marketing.

So we wondered: which local businesses have the top websites?

And, since we partner with the Building Industry Association of Lancaster, we decided to start our research with the Construction Industry. (And we admit it, the Book of Lists is really big!)

If you find this information useful, and you'd like to see research on your industry, let us know!

Note: Because we wanted to focus on local businesses, we omitted CPBJ's Engineering firms and Environmental contractors, many of whom are big firms doing a large percentage of their business outside the local area.

A quick explanation of the research

We researched the website designs of top Construction companies as listed in Central Penn Business Journal's 2019 Book of Lists. Using website design and SEO auditing tools, we collected website analytics scores for each business, then converted them into a standardized Website Rating from 0-100%.

The higher the Website Rating, the more prominent and visible the website is online - meaning more traffic, more backlinks, and better search engine rankings.

The SEO tools and analytics we used included:

Alexa Rank - ranks a website's popularity based on daily visitors and page views. Lower scores are better.
SEMrush Authority Score - measures the overall quality of a domain based on backlinks, organic search metrics, and website traffic. Higher scores are better.
Ahrefs Domain Rating - measures the strength of a website based on the number and quality of backlinks. Higher scores are better.

What we learned

While the website ratings themselves are interesting, here are a few key takeways we learned from our research:

98% of Central PA's top construction companies have websites - If you're going to have a successful, growing business, you need a website. Out of all the construction companies in the Book of Lists, only (2) did not have a website design.
There is a relationship between good Website Design Ratings and higher Revenue - as we expected, having a strong website does play a role in business success. While it's only one piece of your marketing mix, our research did show a moderate correlation between website ratings and revenue figures.
The bigger the company, the stronger the correlation between Revenue and Website Rating - while the smallest businesses showed more variation, larger companies almost always had stronger websites and better scores across the board. The message is clear: if you're looking to really grow your business, a great website that ranks well and brings in traffic is a key part of your marketing.
