Thirteen years of SEO for one client: what actually survives

I’ve run SEO for the same client since 2013. Corporate limousine services in New York and Indianapolis — a market where the customer books on their phone, often within the hour, and whoever appears first usually wins the job.

Thirteen years is long enough to have lived through Penguin, Panda refreshes, Hummingbird, Mobilegeddon, RankBrain, Medic, the BERT rollout, four years of core updates, the helpful content system, and whatever the search results are becoming now that AI answers sit above them.

Most SEO advice is written from the perspective of a campaign that ran for eight months. This is what a decade-plus actually teaches you.

Everything built on a trick eventually costs you

Over thirteen years I watched competitors in that market climb past us several times. Each time it was the same shape: a sudden jump, a few good months at the top, then a fall they never recovered from.

The tactics changed with the era. Bought links. Private blog networks. Exact-match domains. Doorway pages for every suburb. Spun content at scale. Later, AI-generated pages by the hundred.

What did not change was the arithmetic. A tactic works until Google’s next update prices it in, and then the site carries the penalty — sometimes for years. The client pays twice: once for the shortcut, and again for the recovery.

This is why I decline when a client asks me to buy links. It isn’t a moral position. It’s that I intend to still have the client in ten years, and bought links make that impossible.

Technical health is a floor, not a strategy

Technical SEO gets treated as the sophisticated part of the job. It isn’t. It’s the part that stops you losing.

A site that loads slowly, can’t be crawled properly, or breaks on mobile will underperform no matter how good everything else is. But fixing those things does not, by itself, make you rank. It removes the reasons you were being held back.

Over thirteen years the technical requirements changed completely — mobile went from optional to mandatory, then to primary; page speed went from a tiebreaker to a measured ranking input; structured data went from a curiosity to how half the results are displayed. Each shift required real work.

None of that work grew the business on its own. What grew the business was being genuinely the most useful result for someone trying to book a car.

Rankings are not the deliverable

The most useful thing I ever did on that account was stop reporting rankings first.

Position tracking is seductive because it moves weekly and feels like progress. But a client does not deposit rankings. Over the years I have seen a site rank higher and take fewer bookings, and rank lower and take more — because the mix of queries changed, or the page that ranked was the wrong page for the intent behind the search.

The question worth reporting is: how many people contacted the business this month, and where did they come from? Everything else is diagnostic.

This is also the honest way to tell whether SEO is working, because it is much harder to make it look good than a ranking screenshot is.

Core updates hurt sites that were already borrowed against

Every core update produces the same forum posts: sites that lost half their traffic overnight, owners insisting they did nothing wrong.

In thirteen years I have not seen a core update seriously damage a site that was genuinely the best answer for its queries. What I have seen is updates removing the gap between a site’s actual quality and the position it had been holding.

If a site is ranking above where it deserves — through aggressive link building, thin pages that happened to work, or a technical advantage competitors hadn’t caught up to — the update is not the cause of the fall. It is the moment the loan is called in.

The practical version: after an update, the useful question is not “what did Google change?” It is “where was I ranking above what I’d actually earned?”

Content ages, and nobody plans for it

The pages that brought traffic in 2015 were not the pages that brought traffic in 2020, and those are not the ones working now.

Some decayed because the world moved — prices, regulations, the way people phrase the search. Some decayed because competitors wrote something better. Some decayed because the intent behind the query shifted underneath them.

Publishing is only half the job. On a long-running account, a significant share of the work is going back to pages that once worked and asking whether they still deserve their position — updating them, merging them, or removing them.

Removing content improves sites more often than people expect. A site carrying two hundred pages where forty are genuinely good performs worse than a site with forty good pages.

The compounding is real, and it is slow

Year one on that account was unglamorous. Technical cleanup, restructuring, a handful of pages, very little visible movement. The kind of year that makes clients nervous, and rightly so.

What thirteen years buys you is something no new competitor can shortcut: a domain with a long, clean history, pages that have held their positions through a dozen algorithm shifts, and links accumulated slowly enough that none of them look bought.

That position is genuinely hard to attack. A well-funded competitor can outspend you on a campaign. They cannot buy the years.

This is also the honest case against short SEO engagements. Three months is enough to see whether the work is directionally right. It is not enough to build anything. If you cannot commit to a year, the money is better spent on ads, where it converts immediately and stops when you stop paying.

What has actually changed, and what hasn’t

Changed: mobile went from afterthought to primary. Speed became measurable and consequential. Local search separated almost entirely from organic. Search results filled with features that push the traditional listings down. Entire query categories stopped producing clicks at all.

Unchanged: the site that most usefully answers the search, from a business a person is willing to trust, ranks. The mechanism gets more sophisticated every year. The target has not moved.

Thirteen years of watching people chase the mechanism instead of the target is, if I’m honest, the whole lesson.
