Frequently Asked Questions
Ahrefs or SEMrush — which is better for agencies?
Ahrefs for superior backlink data and keyword research. SEMrush for broader functionality including PPC, content, and white-label reporting. Many agencies use both.
Do agencies need paid SEO tools?
Yes — free tools like Google Search Console provide baseline data, but paid tools (Ahrefs, SEMrush) provide competitor analysis, keyword research depth, and client reporting that justify their cost many times over.
How should agencies bill for SEO work?
Track SEO hours in Refront alongside development work. Bill monthly retainers or hourly for SEO services. Transparent time tracking builds client trust in the value of ongoing SEO work.
