Single-URL performance tools are precise and free, and they are the right instrument when you already know which site you care about.

Grow By Lead measures load behaviour as one signal group inside a bulk run, then places it next to everything else that decides whether a business is worth contacting.

Load behaviour and page weight recorded for every site in the queue, comparably.
A slow site with no contact route and no schema is a different conversation from a slow site that is otherwise healthy.

Metrics appear in the full technical audit with evidence and the recommended fix.

Most visitors arrive on a phone. Plenty of small business sites still assume they do not.
Audit hundreds of sites in one managed run instead of opening them one by one.
Qualify a market before you build the campaign, and know which accounts are worth a proposal.
