If you run a business, you have gotten the calls: somebody guaranteeing you the number one spot on Google, usually by Friday, usually for $99 a month. This page is what SEO actually is, in plain language, so the next time that phone rings you know exactly what they are offering (and what they are not).
SEO is making it easy for Google to understand your site and trust your business. That is the whole thing. It has three ingredients: a site Google can read (fast, works on a phone, organized so a machine can tell what you do and where you do it), evidence that real people trust you (reviews, a tended business profile, other sites pointing at yours), and time. There are no secrets and no tricks, because Google's entire business depends on showing people the result they actually wanted. SEO is just convincing it, with evidence, that you are that result.
Nobody has a special relationship with Google. Not him, not me, not the agency with the slick deck. So a guaranteed ranking is a lie on its face: Google does not sell rankings and does not take requests. The $99-a-month package is often a monthly report generated by software, heavy on charts and light on anything that actually moved. The tell is always the same combination: a guarantee plus urgency. Real SEO can promise the work and the direction, never the exact position. If someone guarantees you number one, you do not need this page to know what to do: hang up, kindly.
The technical half of SEO is not an add-on, and you should be suspicious of anyone selling it as one. Fast pages, mobile-first layout, titles and descriptions that match what people search, structured data that tells Google what you are and where you work, a sitemap, and a site wired to your Google Business Profile: that is the foundation, and it ships standard with every site I build. You do not pay extra for the part that should have been done right the first time.
For a local business, the honest levers are unglamorous: a Google Business Profile that stays alive (posts, photos, answered questions), reviews arriving steadily because you ask every happy customer, and time, because Google moves slowly and deliberately when it decides a business is real, local, and liked. Content helps when there is something real to say (answering the questions your customers actually ask, the way this page does), and it is wasted money when there is not. Weeks to months, not days. Anyone selling faster is selling something else.
I do not sell SEO retainers, on purpose: I would rather build things than sit in monthly ranking meetings, and I think you would rather pay for things that get built. So the deal is this: the foundation comes standard with every site, my care plans (from $60 a month) keep it healthy, and the Wide Net plan at $150 a month adds the local-visibility tending, your business profile and your reviews looked after monthly, without anyone pretending that is a growth department. And if the phone rings with a guarantee attached: kindly, hang up.
More straight talk: do you actually need a website?, should you build it yourself?, and do you need a social media manager? Or read the whole series.
