How I decide if SEO is still worth it for a business

Is SEO worth it? What's the short answer by business type?

Is SEO worth it? It's worth it for a business whose customers search before they buy, and a poor use of money for one whose customers don't. The rest is arithmetic and patience. When I can't tell from the outside, that's what my technical SEO audit services are for: they show whether this particular site can be found at all, and what's stopping it.

Here's how the answer usually splits. It's a starting point, not a verdict, because two businesses of the same type can have very different sites and very different competition.

What does SEO cost against what a lead is worth?

I don't start with traffic. I start with what one new customer is worth over the time they stay with you, then with how many enquiries it takes to win one. Those two numbers tell you how many extra enquiries a month the work has to produce before it pays for itself.

The sum is short. Divide the monthly cost of SEO by the value of one customer, and you've got the number of new customers per month that breaks even. Multiply that by how many enquiries it takes to win a customer, and you've got the enquiries the work has to add. If that figure is one or two a month for a business with real search demand, SEO is usually worth a serious try. If it's forty, it probably isn't.

Quotes vary widely, and I've written up how much SEO costs with the ranges and what drives them. Whatever the figure, put it next to your own customer value rather than next to someone else's case study.

SEO vs paid ads: which is worth it for a small business?

They buy different things. With cost-per-click bidding, Google's Ads help says you pay for each click on your ad, so the traffic stops when the budget does. SEO costs money up front and in upkeep, but a page that ranks isn't charged per visit.

The two don't feed each other. Google says advertising with it won't have any effect on your site's presence in its search results, and that it never accepts money to include or rank sites in organic results. So an ad budget doesn't buy rankings, and rankings don't lower the ad bill.

For a small business, running both for a short while is often the useful mix: a small ad budget on the searches you'd want to rank for, which shows within weeks which ones actually turn into enquiries. That tells the SEO work where to aim, instead of guessing.

How long before SEO is worth it?

Longer than most people hope. Google's SEO starter guide says some changes take effect in a few hours and others could take several months, and that you'll likely want to wait a few weeks before judging whether a change worked. I've set out how long SEO takes to work in detail, including why nobody can give you a fixed date.

What the wait looks like varies. One of my case studies went from roughly 10 clicks a day in June to roughly 70 a day in September, after hundreds of location pages went live. That's a strong quarter, and the case study says plainly that most of its impressions were still page two placements.

The other side of the ledger is what neglect costs. A redesign cost one store four fifths of its traffic in three days because nobody mapped the old URLs first. Sometimes SEO is worth it simply as insurance before a change like that.

Is SEO still worth it with AI answers and AI Overviews?

Yes, with fewer clicks on some searches than there used to be. Google's documentation on AI features says the best practices for SEO remain relevant for AI Overviews and AI Mode, with no additional requirements to appear in them. The pages its AI features draw on are still found, crawled and indexed the ordinary way.

The click loss is real, though, and it's worth pricing in. Pew Research Center's analysis of 900 U.S. adults' browsing in March 2025 found that users who saw an AI summary clicked a traditional result in 8% of visits, against 15% for users who didn't see one, and clicked a link inside the summary in just 1% of visits. Pew also found longer, question-style searches produced AI summaries far more often: 53% of searches of ten words or more, against 8% of one- or two-word searches.

Google's side of the story is that clicks from results pages with AI Overviews are higher quality, meaning people spend more time on the site. Both can be true. My reading: SEO built on answering long informational questions is worth less than it was, and SEO built on short commercial and local searches, where people still want a business, holds up better. So is SEO dead now with AI? No, but the searches worth chasing have narrowed.

What is the 80/20 rule in SEO?

It's the Pareto idea applied to a website: a small share of pages, queries or fixes produces most of the result. It isn't a law with fixed numbers, but it holds often enough to plan around.

This site shows it. In Search Console for the 90 days from 27 June to 25 September 2026, 15 of the 73 URLs that appeared in search, about a fifth of them, carried 5,025 of 5,668 impressions, close to 89%. Most of those impressions landed on old URLs that now redirect, which is its own lesson about where attention goes.

I use it to decide whether SEO is worth it at all. If the few pages that could matter, the ones for the searches that turn into customers, can realistically be fixed and ranked, the rest of the site can wait. If even those look out of reach, the answer is probably not yet.
