I’ve sat across the table from business owners who’ve been burned before. A previous agency promised page one rankings, took a retainer for eight months, and delivered a handful of blog posts and a PDF report nobody could quite make sense of.
It happens more often in this industry than it should, and it’s exactly why I think every business owner considering SEO deserves a straight, honest briefing before they sign anything.
I spent years running lead generation for a boiler and solar installation business that scaled past £65 million in turnover, so I’ve been the person justifying marketing spend to a board, not just the person pitching for it.
What follows is what I genuinely wish every business owner knew before they committed a budget to local SEO, the good, the realistic, and the warning signs worth knowing before you sign anything.
What Can An SEO Agency Actually Promise You?
This is the single most important thing to understand before spending a single pound. No agency, including us, can guarantee a specific ranking position on Google. This isn’t a hedge or a legal disclaimer, it’s a fact Google states plainly in its own official guidance for anyone hiring an SEO, warning businesses to be wary of any provider that claims otherwise.
Why Can’t Anyone Guarantee Rankings?
Google’s algorithm weighs hundreds of factors, updates constantly, sometimes multiple times a week, and reacts to competitor activity that no agency controls. Rankings are also increasingly personalised based on location, search history and device, meaning what you see when you search may not match what your customer sees.
Any agency offering a guaranteed page one position within a set timeframe is either misunderstanding how search actually works or planning to use tactics that risk a manual penalty severe enough to remove your site from search results entirely.
What Should A Reputable Agency Promise Instead?
What a genuinely credible partner can and should commit to is specific, measurable deliverables. Things like a defined content publishing schedule, monthly reporting within an agreed timeframe, transparent access to your own Google Search Console and GA4 accounts, and clear KPIs tied to actual business outcomes, qualified leads and booked jobs, not just vanity traffic numbers.
That distinction, between promising outcomes you can’t control and committing to the work you can, tells you almost everything you need to know about whether an agency is being straight with you.
What Questions Should You Ask Before Signing Anything?
Before committing a budget, I’d encourage every business owner to ask a handful of pointed questions, and to genuinely listen to how confidently and specifically they get answered.
What Should You Ask About Strategy And Approach?
Ask exactly how they’d approach your specific site and your specific sector, not a generic answer about “improving visibility.” Ask about their content cadence, their link building policy, and crucially, how they’re adapting to AI Overviews and generative engine optimisation, because an agency still treating local SEO as purely a Google keyword ranking exercise is already behind where search actually is in 2026.
What Should You Ask About Ownership And Contract Terms?
This one catches a lot of business owners out. Ask explicitly who owns your content, your backlink profile and your analytics data. Never sign a contract where the agency retains ownership of assets built for your business, because that leaves you with nothing portable if the relationship ends.
Also scrutinise the notice period and termination terms. Reasonable agencies allow a sensible notice period without demanding you’re locked in for years with no way to pivot if results genuinely stall.
What Should You Ask About Reporting And Accountability?
Ask precisely what gets reported, how often, and in what format. Reports focused purely on impressions or generic traffic numbers, with no connection to leads, conversions or revenue, are a warning sign.
A properly run SEO programme should be able to show you a reasonably clear line between the work being done and the business outcomes it’s producing, even if that line takes several months to become visible.
What Are The Most Common Red Flags To Watch For?
Beyond the guarantee issue, there are a handful of consistent warning signs that show up across the research into agency hiring mistakes, and I’d encourage you to take them seriously rather than dismissing them as generic advice.
Which Red Flags Should Concern You Most?
Choosing an agency purely on price is one of the most expensive mistakes a business can make, because genuinely low-cost providers often rely on outdated or risky tactics that produce short-term movement followed by a painful correction once Google catches up.
Vague explanations of link building methods, an inability to show real, verifiable case studies or Search Console data from previous clients, and no apparent understanding of topical authority or answer engine optimisation are all signs the agency hasn’t kept pace with how search has evolved.
One-size-fits-all packages are another clear signal, because a boiler installer in a competitive city and a solar installer in a rural county need genuinely different strategies, not the same template with your logo swapped in.
What Should You Realistically Expect From The Timeline?
This is where honesty matters most, because unrealistic expectations set at the start of an engagement are one of the most common reasons businesses walk away from SEO disappointed, even when the work was genuinely sound.
Most reputable studies and agencies converge on a similar pattern, early signals within four to eight weeks, meaningful traffic and enquiry growth by months three to six, and reliable, compounding lead volume somewhere between months six and twelve.
Why Does Expecting Results Too Quickly Cause Problems?
If a business commits to SEO expecting a flood of leads within six weeks, disappointment is almost guaranteed, not because the work isn’t working, but because the timeline was set incorrectly from the start.
I always tell prospective clients the same thing I’d want to hear myself, if you need leads next week, paid search fills that gap far better than SEO ever will. SEO is the right tool when you’re planning growth over the next twelve to eighteen months, not the next fortnight.
What Do You Need To Have Ready Internally Before Starting?
This part gets skipped in most agency pitches, but it genuinely affects how quickly and how well SEO performs for your business. Internal readiness matters as much as agency capability. Do you have someone internally who can approve content in a reasonable timeframe, rather than letting drafts sit unreviewed for weeks?
Do you have access to your own Google Business Profile, website hosting and analytics accounts, or has a previous agency locked you out of your own data? Is there organisational buy-in from whoever holds the budget, so the programme doesn’t get paused halfway through the first year right as the compounding effect starts to build?
Why Does Internal Collaboration Matter So Much?
SEO isn’t something an agency does entirely in isolation while you wait for a monthly report. The businesses that get the best results tend to have a genuine two-way relationship, sharing information about seasonal demand, new services, accreditations or grant scheme changes that the agency can then build directly into content and strategy.
A business installing EV chargers, for example, benefits enormously from an agency that knows about upcoming grant changes or infrastructure announcements before they become public knowledge, because that’s exactly the kind of timely content that captures search demand early.
Why Does Sector Expertise Matter More Than General SEO Knowledge?
This is genuinely important for boiler, solar, heat pump, air conditioning and EV charger installers specifically. You’re not competing against the local plumber down the road, you’re competing for visibility against national comparison giants like MoneySuperMarket, GoCompare and uSwitch, businesses with years of accumulated domain authority and enormous content resources.
A generalist agency with no specific experience in this sector will apply generic small business SEO tactics that simply aren’t calibrated for that level of competition.
Every senior person on our team at Essheo has spent eight or more years working specifically in genuinely hard to rank sectors like this one, and the strategies we’ve designed and implemented have contributed to over £45 million in combined client revenue across the last two years alone.
We’ve been on the operational side of a business competing directly against those same national players, which is a genuinely different starting point to an agency that’s only ever advised from the outside.
Ready For An Honest Conversation Before You Commit?
If you’re weighing up SEO investment and want a straight answer, one that includes what’s genuinely achievable, what timeline to expect, and what red flags to avoid, rather than an optimistic pitch designed purely to close the deal, that’s exactly the conversation worth having before you sign anything.
I set Essheo up to give business owners and marketing decision makers precisely that kind of honesty, transparent ownership of your own accounts and data, realistic timelines, and reporting tied to genuine business outcomes rather than vanity metrics. We’ll walk you through exactly what we’d do, why, and what you should expect to see and when.
