The phrase covers firms that do very different work. Some are technical shops that fix what a site does to a crawler. Some are publishers that produce pages at volume. Some are link brokers with a thin layer of strategy on top. Most sell all of it in one retainer, and the useful question at the first meeting is which of those four the firm actually staffs, because that is what you will get whatever the proposal says.
The four things sold under one name
Technical work makes a site crawlable, fast and correctly structured. Content work produces the pages that answer what buyers type. Off site work earns links and mentions elsewhere. Measurement work decides what counts as a result and reports it. A firm that is excellent at one of these is common. A firm genuinely staffed for all four is rarer and costs accordingly, and the mismatch between what is sold and what is staffed is where most disappointment starts.
What the first ninety days usually contain
Most engagements open with an audit, a keyword and page plan, and a fix list handed to whoever owns the site. Very little of that is visible externally, which is why the opening period feels quiet. Ask specifically who implements the fix list. If the answer is that your developer does, then part of what you are buying is a document, and the schedule depends on a team the agency does not control.
Where agency work stops and yours begins
An agency can recommend a page, write it and ask for it to be published. It usually cannot change a product, a price, a shipping policy or a booking flow, and those often decide whether the traffic converts. Agree in writing which side owns publishing, which owns the content management system and who can approve a change, because unresolved ownership is the most common reason a plan stalls after month two.
How to read the reporting
Rankings move before traffic does and traffic moves before revenue does, so early reports lean on leading indicators. That is legitimate, but insist that the report also names the commercial number it is aiming at and shows it, even while it is flat. A report that only ever shows the metric that happens to be rising is a marketing document rather than an account review.
Questions people ask about what is an seo agency
Is an SEO agency different from a digital marketing agency?
An SEO agency concentrates on earned search visibility. A digital marketing agency usually also buys ads, runs social channels and sends email. Some SEO firms are specialists by choice and will tell you plainly that paid media is somebody else's job, which is often a good sign rather than a gap.
How long before an SEO agency shows results?
It depends on the site's existing authority, how competitive the queries are and how quickly fixes actually get published. A firm that promises a date without having seen your site or your competitors is guessing, and the guess is being made to win the pitch.
What should an SEO agency never promise?
A specific rank position, a guaranteed date for one, or a relationship with the search engine that gets you special treatment. Search engines publish their own guidance and it is explicit that no one can guarantee placement.
Do I need an agency at all, or a hire?
If search is a permanent channel for you and the work is continuous, an internal hire eventually costs less. Agencies earn their keep where the work is bursty, where you need several specialisms at once, or where nobody internally can yet judge what good looks like.
