What an SEO service agency should put on the table before you sign
An SEO service agency asks you to buy months of work on the promise of compounding results, which makes the purchase a trust exercise, and trust has checkable proxies. Before any signature, a strong agency will show you specifics: what it would do first on your site and why, work it has done for named clients, its actual method against Google's published guidance, and pricing you can compare. This page is the pre-signature checklist, and the index behind it compares 134 agencies on exactly those disclosures.

The pre-signature checklist
- Get the first-quarter plan in writing. Not the framework slide: the actual first ninety days for your site. Which technical issues, which pages, which queries, what ships each month. Agencies that answer specifically on the sales call are showing the product; agencies that answer after signature are showing the sales process.
- Interrogate two case studies properly. Client named or verifiable, starting position, what was done, results in real units over a stated period, and what did not work. Google's guidance for hiring an SEO says ask for previous work; the follow-up questions are where case studies become evidence or dissolve.
- Map the method to the rulebook. Ask how they build links and produce content, then read the answers against Search Essentials and its spam policies. Merit-earned links and useful content are the durable method; guaranteed placements, bulk products, and secret techniques are the named warning signs.
- Compare pricing on itemized scope. Retainer numbers are incomparable until each is itemized: strategy hours, content shipped, technical work, links, reporting. This index favors agencies that publish pricing, because a published price is the first disclosure and the easiest one to refuse to make.
The engagement structure that protects both sides
Accounts stay yours (Search Console, Analytics, the site, any profiles), with the agency granted revocable access. Deliverables are named monthly, with links to what shipped. The exit clause returns everything: content, research, disavow files, reporting history. No long lock-in before trust is earned; a quarter-by-quarter commitment prices the agency's confidence in its own work. None of this is adversarial; strong agencies propose it themselves because it filters the clients who churn.
Reporting deserves one specific demand: outcomes by source, not activity. Rankings for the agreed queries, organic entrances to money pages, and the enquiries or revenue those produced. Activity metrics (posts published, links built, hours logged) belong in the appendix as evidence of shipped work, never as the headline. An agency whose report leads with its own busyness is reporting on itself.
Sales patterns that predict a wasted year
The reliable red flags are documented by Google itself and confirmed by every burned buyer: unsolicited outreach promising rankings, guaranteed first-page results, claimed special relationships with search engines, secret proprietary methods that cannot be described, and pressure to sign multi-year terms today. Each one is a prediction about how the engagement will treat you after the invoice clears, and each is visible before it does.
The subtler tells: a pitch that never asked about your business model, a proposal identical for any company in your industry, senior people in the sale who vanish after signature, and reference clients all from the last six months. The counter-move is the same in every case: force specificity about YOUR site, YOUR queries, and YOUR first quarter, then judge the answers. Specificity is expensive to fake, which is what makes it the test.
Questions people actually ask
- What is the single best question to ask an SEO agency?
- Which three changes would you make first on our site, and why? It tests whether they looked, whether they can prioritize, and whether they will show the product before the contract.
- How long should I commit for?
- Quarterly renewal after an initial project or quarter is the honest structure. SEO takes time, but time is an argument for measured patience, not for a two-year lock-in signed on day one.
- Should the agency have ranked for its own keywords?
- It is fair evidence: an agency invisible for its own competitive service phrases is asking you to buy what it could not do for itself. Weigh it alongside client results rather than alone.
