Choosing a digital marketing SEO company on evidence

Agencies with a verified published price

How to shortlist a digital marketing and SEO company

1. Name your constraint before you read a single proposal. Write down the one thing that is limiting revenue: not enough people know you exist, people find you and do not enquire, enquiries arrive and do not convert, or customers convert and do not return. Each points at a different channel. Agencies will happily sell you all four solutions at once, and a proposal that responds to a named constraint is far easier to compare than one that responds to a wish.
2. Make every candidate price the bundle line by line. Ask for the proposal split into channels with hours or deliverables against each, and ad spend shown separately from management fee. A bundled monthly number is not comparable with anything. Once the split exists you will often find that the channel you care about accounts for a small share of the fee, which is the single most useful thing a shortlist can tell you.
3. Check who does each channel, and where. Full service usually means some services are subcontracted, which is normal and not disqualifying but changes accountability and turnaround. Ask for the named team per channel, their titles, expected hours per month, which functions leave the building, and what happens when the named lead departs. Ask specifically who writes the content, because that is the most commonly outsourced piece.
4. Set measurement and ownership terms before the first invoice. Agree what counts as a lead, insist that reporting separates brand from non-brand organic traffic, and require a plain monthly statement of what changed and why. Create the analytics property, Search Console access, ad accounts and tag manager in your own name and grant agency access. Google's hiring guidance recommends read access for an audit rather than write access to your site.

What full service agencies publish, and what stays hidden

Our index records what each agency states on its own website: published pricing or starting fees, disclosed minimum engagements, named clients, and which services are delivered in house. Where a figure is not published we record it as absent rather than inferring one, because a guessed price gives a buyer nothing to negotiate against and quietly becomes a fact once it is repeated.

The consistent pattern in the full service category is that minimums are disclosed more often than rates, and that the channel split inside a retainer is almost never published. That second gap is the one that costs buyers most. A published minimum tells you whether an agency is sized for you; only a line-by-line proposal tells you whether the money lands where your revenue comes from.

When a bundle is the right purchase, and when it is not

Bundling earns its keep when the channels genuinely feed each other and one team can act on what the others learn: search query data shaping content, paid search testing messages before organic pages are written, email capturing demand that search created. It also saves real coordination time for a small marketing team with nobody to run vendors, which is a legitimate reason to pay for it.

It is the wrong purchase when one channel plainly dominates your economics. If almost all your revenue comes from local search, a bundle that spends a third of the fee on social content is a tax. Specialists usually go deeper and cost less per channel, at the price of you doing the coordination. Decide which of those two costs you would rather pay, then buy accordingly rather than defaulting to whichever the pitch recommends.

Reading claims and case studies before you sign

Ask for the client name, the starting position, the date range and what else ran during the period. Traffic growth that is not separated into brand and non-brand is the most common flattering presentation in this industry, because brand search rises for reasons that have nothing to do with the agency. Google's spam policies are worth reading before you buy link building, because tactics that were normal a decade ago are now explicitly described as violations.

Where testimonials, reviews or endorsements appear, they are advertising and the Federal Trade Commission's endorsement guides apply, including that a claimed result should reflect what customers can generally expect and that material connections between an endorser and the advertiser must be disclosed. An agency that volunteers the limits of its own best case study is telling you something useful about how it will report to you.

Questions people actually ask

Is a full service agency better than hiring specialists?

Neither is better in the abstract. A bundle buys coordination and one point of contact, which is worth real money if you have nobody internally to manage vendors. Specialists buy depth and usually cost less per channel, but you carry the coordination. Choose based on whether your bottleneck is expertise or management capacity, and be honest about which one you actually have.

How do I compare bundled proposals that all quote one monthly figure?

Insist on a split by channel with deliverables and hours against each, and ad spend shown separately from fee. Then normalise the proposals on the channel you care most about. Candidates who will not provide the split are asking you to buy on trust, which is a reasonable thing to decline at the shortlist stage rather than after six months.

What is a realistic timeline for results across channels?

Paid search buys existing demand and can produce enquiries in days. Listings and technical fixes move within weeks. Content and organic rankings compound over months, longer in competitive categories. Email works on the audience you already have, so it returns quickly and plateaus. Judge each on its own clock rather than on a single blended promise made at the pitch.

What should I own rather than the agency?

The domain, the website and its files, the analytics property, Search Console access, the tag manager container, every ad account and any call tracking numbers. Create them yourself and grant access. Agency-owned assets are the most common and least visible switching cost, and they only become apparent on the day you decide to change providers.
