What Does an SEO Agency Do Each Month? A Line-by-Line Look at the Work

What does an SEO agency do each month? Fix the site, tune the pages, add content, earn mentions, report back. Whether that report connects the work to buyer conversations is the only question worth chasing.

Let’s talk about the PDF. It lands on the fifth of every month, with a line chart that always seems to point up and to the right, and below it a block of bullets under the heading Work Completed: on-page optimization, technical review, ongoing efforts. (I invented that one. You’ve probably got its cousin sitting in your inbox.)

Is anyone lying? No. The work probably happened. But a task list can’t tell you whether a single buyer showed up because of it, and busy has never been a synonym for useful.

So why do owners nod and file it away? Because SEO is hard to see from the outside. The vocabulary alone is a moat, and asking what technical review means feels like confessing you’re behind. A quarter goes by. Then another. On a status page, activity and progress look like twins.

The rest of this post is the work, line by line, so each line can be checked against something you can open and read yourself.

What Does an SEO Agency Do? The Plain Version

An SEO agency is an outside team you pay to improve how your site shows up in search. Google spells out what providers offer on its page about hiring an SEO, which covers reviewing site content and structure, technical advice, content development, keyword research, training, and optimizing for generative AI.

Nouns, all of them. Nothing about what happens in March.

Loops make more sense to me. Look at what happened. Fix what’s broken. Polish the pages that matter. Add what’s missing. Decide what next month is for.

A Month of SEO Work, Line by Line

Seven lines come next, and each one should leave something behind that you can point at. If a line leaves nothing, ask where that time went, and don’t accept a shrug as the answer, because a shrug is what a month of unexamined activity usually sounds like.

The Monthly Work at a Glance

Rankings sit in the first row as one input. One. They aren’t a line of work, no matter how big the chart on the cover page is.

The Lines in More Detail

Measuring Comes First

Search Console’s Performance report carries the weight here. Google says it shows how your search traffic changes over time, where it comes from, and which queries bring it.

The good version of this line is dull. Somebody lines the report up against last month and the same month last year, writes down what moved, and guesses at the reason. That guess is the whole value. Without it, a chart is just wallpaper.

Technical Work Should Shrink

Technical work is the unglamorous checking and fixing of whatever stops a search engine from reading your site, from crawl rules and redirects to error pages, JavaScript and speed. Google’s Core Web Vitals page wants a Largest Contentful Paint inside 2.5 seconds of the page starting to load, so at least a speed fix comes with a target.

Month one, this line should be huge, because somebody is meeting your site for the first time and opening the junk drawer. Month six, I’d expect a short list of small repairs. If it’s still the biggest line at month nine, then either the site keeps breaking or the line is stuffing the report, and you get to ask which. (My working view, not a Google rule.) For the whole technical picture, there are our technical SEO services.

Pages and Content, the Part You Can See

Page work edits what exists. Content work adds new pages or rebuilds old ones. Open the result in a browser, either way.

Agencies that only crank out new posts may be dodging the cheaper win, since a page that slowly bleeds clicks sometimes needs a repair rather than a replacement, which is the whole subject of our post on content decay. And ask for the before and after. Every time.

Links and Mentions, Earned and Never Bought

Links make people nervous, and they should. Google’s spam policies define buying or selling links for ranking purposes as link spam, and its hiring page says you should never have to link to an SEO. Meanwhile the SEO starter guide notes that links from other sites happen naturally over time.

So legitimate work looks slow. Write something worth citing. Pitch it to the sites your buyers read. Fix the mentions that already exist. If the monthly line only says backlinks acquired, ask for the list, where each one came from, and why a buyer reading that site would trust it, because a number on its own proves nothing at all.

AI Answers Run on the Same Foundations

Everybody’s selling AI visibility this year, so check what Google itself says. Its page on AI features and your website says AI Overviews and AI Mode have no additional technical requirements beyond a page being indexed and eligible to show with a snippet, and that the usual SEO foundations apply.

Is the work pointless, then? No. Somebody still checks which questions your buyers ask, whether your pages get quoted, and whether a page can be lifted cleanly into an answer. I’d just want it explained in terms of the other six lines, not sold as its own mystery. We dig into the difference in AEO versus GEO.

Review Sets the Next Month

Last line, last job: decide. What worked, what didn’t, what next month is for. In writing. If next month’s plan looks identical to this month’s, nobody reviewed anything, and you can usually tell within five minutes of reading the report, because the same three fixes and the same two posts show up under a new date.

What Does an SEO Agency Do in Month One, and in Month Nine?

Different jobs, different months. Month one is access, a baseline and a heap of fixes. Months two and three go to the pages buyers actually land on. After that the weight moves to refreshing, earning mentions and checking AI answers while technical work settles into upkeep, and a site with a messy history (stitched together by a few vendors over the years, say) will stay on the early work longer than this tidy outline lets on. Fine. That’s normal.

On timing, Google is blunt. Its starter guide says some changes take effect within hours and others could take several months, and it suggests waiting a few weeks before judging whether your work helped. So wait. A month-one report with no ranking jump isn’t a failure. A month-one report with no fixes, no baseline and no plan is.

What Shouldn’t Be on the Invoice

Google’s page on hiring an SEO gets oddly blunt about warning signs. Consider it your walk-away list. We turn it into a buying checklist in choosing an SEO agency.

• A promised number one ranking. Nobody can promise one, and Google says that outright.
• A “special relationship” with Google, or a “priority submit.” Both made Google’s warning list.
• Link schemes. Paid links for ranking count as link spam, and since Google says you answer for whatever a hired company does, a bad link plan lands on your site, not theirs.
• Secrecy. A provider unwilling to explain planned changes, or to share every change made, doesn’t get the contract.
• Padding. Google Search doesn’t use the keywords meta tag, according to the starter guide, and keyword stuffing breaks its spam policies, so a line item for either is filler.

More lines aren’t more progress. They’re just more lines. A long invoice with nothing connected is only a longer list.

How to Read the Monthly Report

Borrow a habit from the network operations center. Judge an MSP’s NOC on ticket counts alone and you’d cheer a busy week while a client’s network sat dead. Tickets closed says the team worked, but it can’t say whether the client’s network was actually up when the client needed it, and an SEO task list has the same flaw. Same trap, different dashboard.

Task List vs. Useful Report

So ask what these reports leave out. How many conversations started in organic search this month? Analytics and your CRM can answer it, and the agency can be asked to show it. Traffic that never turns into a conversation is a vanity number. Looks like progress. Isn’t.

No answer yet doesn’t make the agency bad. Tracking may never have been set up, which is a month-one fix, though until it is, nobody can say what the work is worth or whether next month ought to look any different from this one. Fixable. For one way this goes sideways with AI search, read why an MSP’s SEO agency can’t get it into AI search.

Questions to Ask Before You Hire

Google’s page has an interview list worth borrowing. Here’s a reworded version for a tech company buyer, close to the original. Use it as written. Once you have a shortlist, our SEO RFP template helps you compare providers on the same questions. Before you sign with the one you pick, read what to check in an SEO contract.

• Can I see earlier work, and talk to someone who paid for it?
• Do you follow Google’s Search Essentials, and do you point to Google’s own documentation when you recommend a change?
• What results do you expect, in what timeframe, and how will you measure them?
• What do you know about my industry? An MSP’s buyers search differently from a retailer’s.
• Will you share every change you make to my site and the reasoning behind each one?
• If you offer an audit, I’m starting you on read access to Search Console. Write access comes later, if at all.

Notice what’s missing. Price. This post stays on the work, since a price means little until you know what’s inside it.

SEO is one lane in a growth system. It works when the report connects to pipeline, the site connects to sales, and one person owns the whole picture instead of each vendor owning a slice while nobody checks the seams. Without that you buy more activity and keep the same business. So the better question isn’t what the agency did this month. It’s what changed for a buyer. If you’d rather have the month run for you, see our managed SEO services for MSPs and IT companies, and the SEO onboarding checklist shows what a partner needs from you on day one.
