What to Ask a Technical SEO or Website Speed Company Before You Hire Them: 7 Questions Most Contractors Skip

The Short Answer

Vetting a technical SEO or speed company before you hire them starts with one thing: making them show you proof, not promises. Before you hire anyone for technical SEO or website speed work, ask them to show you your current Core Web Vitals scores, explain exactly what they will fix and why it affects rankings (not just “speed”), give you a before-and-after report after the work is done, and tell you plainly whether the fix requires ongoing maintenance or is a one-time project. A vendor who cannot answer these seven questions in plain language, without hiding behind jargon, is usually selling a service they cannot actually measure.

Why Technical SEO Is the Easiest Service to Oversell

Technical SEO and site speed work is uniquely hard for a contractor to evaluate. You cannot see the fix the way you can see a new website design or read the copy the way you can read a blog post. Most of the work happens in code, server configuration, and analytics dashboards that never surface to you directly — which makes it the easiest service on this list to bill for work that either was not needed or was never verified to have worked.

That does not mean technical SEO is unimportant. Site speed and crawlability are real ranking factors, and a genuinely broken technical foundation can hold back content and links that would otherwise perform. The problem is that “technical SEO” is also the phrase used to justify vague monthly retainers with no measurable before-and-after, which is exactly what these questions are built to catch.

7 Questions Most Contractors Skip Before Hiring a Technical SEO or Speed Company

1. “Can you show me my current Core Web Vitals scores right now?”

This should take under two minutes using a free tool. If a vendor cannot pull this up on the spot, or tries to reframe the question around something vaguer like “overall site health,” that is a sign they have not actually audited your site before pitching you.

2. “What specifically are you going to fix, and why does that particular thing matter?”

“We’ll optimize your site speed” is not an answer. “Your hero image on the homepage is 4MB and uncompressed, which is adding roughly two seconds to your load time on mobile” is an answer. If every explanation stays at the level of the first example, you are being sold a category of service, not a diagnosis of your actual site.

3. “Will I get a before-and-after report once the work is done?”

Technical fixes are one of the few marketing services that can be verified with a simple screenshot: a Core Web Vitals or PageSpeed score before the work, and the same score after. A vendor who will not commit to this upfront is telling you they do not expect the number to move, or does not plan to check.

4. “Is this a one-time fix or an ongoing retainer, and why?”

Some technical issues really are one-time: compressing images, fixing broken redirects, cleaning up duplicate pages. Others genuinely need ongoing attention as a site grows and content gets added. A vendor should be able to tell you honestly which category your specific fixes fall into, rather than defaulting every technical engagement into an open-ended monthly retainer.

5. “How does this affect rankings specifically, versus just user experience?”

Site speed and technical health affect rankings, but they are one signal among many. Search Engine Journal’s own analysis of page speed as a ranking factor is consistent with what Google has said directly: speed matters most as a tiebreaker and for genuinely poor-performing pages, while content quality and relevance still carry more weight overall. A vendor who promises that fixing your site speed alone will meaningfully move rankings for competitive local terms is overselling a real but secondary factor.

6. “What happens to my current site during the work?”

Technical fixes touch code, hosting, and sometimes your CMS directly. Ask what backup exists before changes are made and what the rollback plan is if something breaks. A vendor with a real process will have a clear answer here without needing to think about it.

7. “Can you show me an example of this exact kind of fix on another site, with real before-and-after numbers?”

Not a portfolio of pretty websites — a specific technical fix, on a specific site, with a measurable result. This is the fastest way to separate a vendor who does this work regularly from one who is adding “technical SEO” to a service list because it sounds valuable.

What a Real Technical SEO or Speed Company Diagnosis Looks Like

A legitimate technical audit produces a short, specific list: which pages are slow and why, which pages are not being indexed and why, which redirects are broken, and which of those actually matters for the keywords you care about. If what you receive instead is a long generic checklist that could apply to any website in any industry, with no site-specific findings, that is a sales document, not an audit.

Should You Vet a Technical SEO or Speed Company, or Just Check This Yourself?

You can check your own Core Web Vitals scores for free in a few minutes, and it is worth doing before any conversation with a vendor so you know whether you are starting from a real problem or a manufactured one. Fixing what you find is a different matter: image compression and basic cleanup are within reach for a motivated owner with some time, but server-level fixes, redirect audits across dozens of pages, and code-level speed work usually require someone who does this daily.

The honest dividing line is time and risk, not difficulty: a botched technical change can take a working page offline or tank its rankings, which is a real cost if you are not confident in what you are changing. If your site already scores reasonably well and you just want it maintained, DIY monitoring plus an occasional professional check-in is often enough. If your scores are genuinely poor and you do not have hours to spend learning server configuration, that is when hiring makes sense.

Frequently Asked Questions

How do I check my own Core Web Vitals score for free?

Google’s own PageSpeed Insights tool is free and is the same baseline tool most technical SEO providers use themselves, so there is no reason a vendor should be unable to show you the same numbers.

Is site speed really a ranking factor, or is that overstated?

It is a real factor, particularly for mobile searches, but it is one signal among many rather than the dominant one. Be skeptical of any vendor who implies speed fixes alone will meaningfully move rankings for competitive terms.

What’s a reasonable timeline for technical SEO fixes to show results?

Site speed improvements are often measurable immediately after the fix. Any resulting ranking movement, if it happens, typically takes several weeks to a few months to show up, similar to other on-page SEO changes.

Can bad technical SEO work actually hurt my site?

Yes. A mishandled redirect audit, an accidental noindex tag, or a broken code change during a “speed fix” can take pages out of search results entirely. This is exactly why question 6 above, about backups and rollback plans, matters.

Do I need technical SEO work if my site already loads fast?

Not necessarily. Technical SEO covers more than load speed — indexing issues, broken redirects, and duplicate content are all part of it — but if your Core Web Vitals scores are already solid with no obvious crawl errors, you may not need a dedicated technical engagement right now.
