Every firm that asks how long SEO takes for accountants is really asking a different question: when can I stop paying for this out of hope and start paying for it out of results. That is a fair question, and "six to twelve months" is a non-answer.

Our position is that the timeline is set mostly by your starting position, not by effort or spend. A firm with a two-year-old site, forty indexed pages and a handful of local citations moves in weeks. A firm with a five-page brochure site built in 2019 and no service pages is starting from zero and will take three to four times longer to see the same enquiry volume. Same work, different runway.

Below we set out the timelines we actually see by starting position, and the leading indicators that tell you the system is working long before rankings, traffic or enquiries move.

The "six to twelve months" figure comes from averaging wildly different situations. It bundles a firm rebuilding a domain that already has authority with a firm registering a domain last Tuesday, and it treats every keyword as equally contested.

Two variables drive almost all of the variance.

The first is domain history. Google has years of behavioural data on an established site and very little on a new one. An established domain that publishes a well-structured service page for a specific niche can be indexed and ranking on page two within a fortnight. A new domain publishing the same page can sit in the low hundreds for two months before anything shifts.

The second is keyword contest. "Accountants in Manchester" is fought over by hundreds of firms plus three directory sites with enormous authority. "Accountant for veterinary practices" is fought over by almost nobody. Those two phrases have timelines that differ by a year or more, and the second one converts better because the intent is sharper.

So when someone gives you a single number, they are averaging away the only two things that determine your answer.

These are the patterns we see across firms we have implemented for. They are observed ranges, not promises, and they assume the work is actually being done rather than a monthly report being emailed at you.

The last row is the one worth reading twice. Niche targeting compresses the timeline more than any other single decision, because you are competing in a market where nobody has bothered to build a proper page. Prads at Wings Online Filings went from five to seven enquiries a month to fifteen to sixteen, and nine new clients, in the first two and a half months on the back of SEO architecture and a content system. That was not luck with the algorithm. It was choosing ground that was not already occupied.

Rankings and enquiries are lagging indicators. By the time they move, the decision that caused them was made three months ago. If you only monitor those two numbers, you will spend the first quarter unable to tell a working system from a failing one.

These are the signals we watch instead, roughly in the order they appear.

• Indexation and crawl coverage. New pages appearing in Search Console within days rather than weeks. If Google is not indexing promptly, nothing downstream matters.
• Impression growth on target queries. Impressions rise long before positions do. A page sitting at position 34 with rising impressions is on its way up.
• Average position drift within pages 3 to 5. Movement from 47 to 28 feels like nothing because it produces no traffic. It is the clearest early evidence of progress.
• Query breadth. The number of distinct queries a page appears for. Breadth expanding means Google is building confidence in what the page is about.
• Branded search volume. People searching your firm name directly. This lags content but leads conversion.

Review these monthly. If impressions and query breadth are flat after eight weeks on an established domain, something is structurally wrong and waiting will not fix it.

In our experience the delay is rarely Google. It is the firm.

The most common cause is publishing volume. A content plan agreed in January that produces four pages by June has not been tested. It has been postponed. Search rewards consistent publication into a coherent structure, and a firm in the middle of a self assessment run will always deprioritise a landing page.

The second cause is structural. Firms bolt blog posts onto a site that has no service pages for the things they actually sell. Traffic arrives, reads a general article about VAT thresholds, and leaves, because there is no page that says "this is what we do for businesses like yours and here is how to start". We wrote about that failure mode separately in Why Your Accounting Firm Gets Website Traffic but No Enquiries.

The third is abandoning the work at month four. This is the expensive one. Four months is precisely when impressions are climbing and enquiries have not arrived yet, which is the moment the investment looks worst on paper and is closest to paying. Firms that stop there pay the full cost and collect none of the return.

The gap between starting SEO and getting enquiries from it is a cash flow problem, and it should be treated as one rather than as a test of patience.

We generally recommend running a paid or outbound channel alongside search for the first two quarters, sized to cover the acquisition you need while the organic asset builds. Paid search and Meta produce enquiries in the first fortnight. Registry-data outbound does something similar; Chris at Thomas Emlyn Ltd runs thirty to fifty cold leads a month producing five to ten booked meetings, which is enough to keep the pipeline honest while slower channels mature.

The point of the paid layer is not to replace search. It is to remove the pressure that causes firms to cancel SEO in month four. It also gives you real conversion data. If your paid traffic converts at a poor rate, your organic traffic will convert at a poor rate too, and you have learned that in three weeks rather than seven months.

One caution from the AccountingWEB forums worth taking seriously: a small daily budget on badly structured campaigns can burn through a month with clicks and no conversions. Paid is a bridge, and it needs the same structural discipline as search.
