Start with your goal. SEO, Google Ads, social media management, content and email are different disciplines, and many agencies specialise. Be clear on whether you want more leads, more sales, more bookings or brand awareness, then find an agency that delivers that.
Ask for results and references, not just a pretty pitch. Look for case studies, current client examples and clear reporting on the metrics that matter to you. Beware anyone guaranteeing a number-one ranking or instant results.
Check the commercials. Understand the monthly cost and what is included, the contract length and notice period, and crucially that you own your accounts and data (Google Ads, Analytics, your website). A good agency is transparent and easy to work with.
It varies widely. Small retainers might start around $1,000 to $2,000 a month for SEO or social, while Google Ads management is often a fee plus your ad spend. Agree the scope and total monthly cost before you start.
They do different jobs. Google Ads can drive traffic immediately but stops when you stop paying; SEO builds lasting organic visibility but takes months. Many businesses use both. A good agency will recommend the right mix for your goals and budget.
Typically three to six months to see meaningful movement, and longer in competitive markets. Be wary of any agency promising instant results or guaranteed rankings, which is not something anyone can honestly promise.
Clear, regular reports on the metrics tied to your goals, traffic, rankings, leads, conversions and return on ad spend, with plain-English commentary. You should always understand what you are paying for and what it is achieving.
Some agencies use fixed terms, others work month to month. Always check the contract length, notice period and any setup fees before signing, and make sure exit terms are reasonable.
You should. Insist that your website, domain, Google Ads, Analytics and social accounts are owned by you, with the agency given access. This protects you if you ever change providers.
