Fernly vs Semrush
Semrush is an excellent tool for auditing websites you already have as clients. It is not a prospecting tool. If you are trying to build a pipeline of new local SEO clients, here is what you need to know.
TL;DR
- •Semrush analyses existing websites; Fernly discovers businesses that have no website at all, which Semrush cannot see.
- •Fernly starts at £19/mo; Semrush starts at £108/mo, making it hard to justify for freelancers who primarily need prospecting.
- •The tools complement each other: use Fernly to find and sign clients, then use Semrush to deliver SEO retainer work.
The short version
Semrush is for analysing existing websites
Semrush is built to analyse websites that already exist and rank in search engines. Its keyword data, backlink audits, and site audit tools are genuinely excellent for retainer work. But you have to already know which website you want to analyse. It cannot help you discover businesses that have no website at all.
Fernly finds the businesses Semrush cannot see
Fernly pulls live data from Google Places and surfaces businesses that are completely missing from the web. Those businesses have no keyword rankings, no backlinks, and no Semrush profile. They are invisible to every SEO tool on the market. That is exactly why they need you.

The prospecting problem Semrush cannot solve
To use Semrush for prospecting, you have to manually search Google for local businesses, visit their websites one by one, and then run each domain through the tool to assess its SEO health. It works, but it is slow and it completely misses businesses that have no website at all. A local electrician with no online presence will never appear in Semrush because there is no domain to analyse.
Where these tools work well together
Fernly and Semrush serve different stages of the same business. Use Fernly to find and sign new local clients through proactive outreach. Use Semrush to deliver the SEO retainer work once they are on board. They complement each other rather than compete. The mistake is trying to use Semrush as a prospecting tool before you have a client in front of you.
The cost difference is significant
Semrush Pro starts at around £108 per month. That is a meaningful overhead for a freelancer or small agency. Fernly starts at £19 per month. If your primary need is finding new clients rather than delivering existing retainers, paying for a full Semrush subscription is hard to justify until you have a stable client base that actually needs those tools.
Find clients. Then audit their sites.
Start with Fernly to build your local SEO client pipeline. Bring Semrush in once you have retainers to deliver.
