How to tell if your SEO agency is doing real work
The checks that separate genuine search work from a monthly report, what you can verify yourself and why a guarantee is the clearest warning sign.
The report that tells you nothing
A deck arrives every month. Graphs trend upward. There is a table of keyword positions and a figure for backlinks built. After reading it you still cannot say what anybody did to your website. That is not an accident of formatting. The document is produced by the party being assessed and most templates in circulation are built to resemble progress.
The question worth asking is therefore not whether the numbers moved. It is whether identifiable work happened on identifiable pages and whether a competent person would have chosen that work. Those are two separate checks and the first one is entirely within your reach.
What this check does not cover and what it costs
Verifying that work happened does not tell you the work was good. A hundred pages of weak content is real activity and a poor decision. Judging quality needs an independent opinion and an audit bought from another agency carries an obvious incentive to find fault. Read any such audit with that in mind.
The cost of the check itself is about an hour of your own attention each month. The larger cost is being willing to act on what you find. A one off independent review is an optional expense and like every professional fee it attracts GST at 18%. Nothing here requires technical skill. It requires reading what you are sent and comparing it with the website.
When to run this and when not to
Run it on any retainer large enough to matter and run it quarterly rather than weekly. Run it before renewing a contract rather than six months into the next term.
Do not run it two months into an engagement. Search work compounds slowly and demanding visible output early pushes an agency towards producing things that look like deliverables rather than things that help. Do not run it if you have already decided to cancel because the exercise then costs both sides time and settles nothing. And be careful what you choose to measure. An agency held to a rank report will deliver rank reports and will drift towards the tactics that move them fastest which includes buying links. That is a risk you created by choosing the measure. If you are not prepared to read a change log and form a view then this check will not help you.
The five things to ask for
First a dated change log. Which URL changed what changed on it who approved it and when it went live. This is ordinary practice and an agency doing the work has it already. An agency that cannot produce one is telling you something.
Second your own access. Search Console and analytics in your own account rather than screenshots in a document. Third the actual link list. Not a count but the URLs where links were placed. Open them. Judge whether these are sites a human reads or a ring of unrelated blogs with a page inviting contributions. Fourth one complete piece of published content. Read it and ask whether you would send it to a customer.
Fifth ask what they decided not to do and why. A practitioner who knows the subject has opinions about which popular tactics are a waste of your money and will give them readily. Ask also who performs the work and whether any of it is subcontracted. Neither question is rude and both answers are informative.
The numbers to judge by and the ones to ignore
Judge by non brand clicks and enquiries grouped by landing page across quarters set against the change log. That pairing answers the only question that matters which is whether the work done produced demand you did not have before.
Ignore position reports generated by the agency's own tool because the tool and its settings are theirs. Ignore counts of keywords in the top ten because the set of keywords is chosen. Ignore domain authority scores because no search engine uses them. Ignore total traffic because your brand sits inside it. Ignore activity counts entirely. Links built and posts published measure effort rather than effect and an agency paid for effort will supply it.
The common mistake and the warning sign
The expensive mistake is judging the engagement by the report for a full year. The graph stays ambiguous long enough to survive four quarterly reviews and by the time a flat line is undeniable you have lost the budget and the year of compounding that careful work would have produced. Ask for the change log in month two instead.
One more thing is worth stating plainly. No agency can promise rankings because the result is decided by a system nobody outside Google can see and by what rivals do next. The absence of a guarantee is normal and honest. A guarantee of first position or of a fixed number of leads is the single clearest warning sign available to you because the only way to promise it is to not understand the system or to assume you will not check.
