WooCommerce Review from Amanda Viviano
We hired Qolos to build our local florist shop's website on WordPress and WooCommerce, and we couldn't be happier with the results. From the start, they took the time to understand our business and created a site that's not only beautiful but easy for our customers to browse and shop.The WooCommerce setup was seamless, our online ordering works exactly the way we needed it to. But what really sets Qolos apart is their ongoing monthly maintenance. We never have to worry about updates, security, or technical issues because they stay on top of everything. Any time we've had a question or a small change request, they've been responsive and professional.As a small local business, it means a lot to work with a team that genuinely cares about keeping our site running smoothly. Qolos has been a true partner, not just a vendor. Highly recommend them to any local business looking for reliable web design and maintenance!

Web Development Review from Sanjay Singh
I kept getting negative reviews about my app for technical glitches, heating issues, functionality, loading time, crashing, and more bugs. So, I reached out to QOLOS after going through 2-3 renowned review platforms. I explained my app issue to the team, and they did tremendous work with their mobile testing solutions. Also, I wanted to build a website for my app. They created a feature-rich and seamless website.

Working with QOLOS was the best decision I have made in regards to scaling my business.

The designer of our logo and website did it well and I am so impressed and proud of the final product! the designer listened and knew exactly what I wanted which made the process so simple. Seriously could not recommend QOLOS more!

I agree with the other review. This company claims that they can build websites and that they are located in Modesto, California which is not true. I have been calling them for weeks and so far no response. When I told them that I wanted a refund, they quiclky put some items on the website. They are very dishonest

4 Frequently Asked Questions About Technical SEO Agencies
Do technical SEO consultants fix site problems, or just find them?
Most technical SEO services providers are excellent at identifying problems. Fewer are structured to resolve them. A 200-page audit with no execution pathway is a liability, not an asset. During shortlisting, demand evidence of shipped fixes, not case studies built around traffic charts. Fixing critical crawl errors increases organic traffic by 20-35% on average within 3-6 months, but only after the fixes are deployed, not after the audit is delivered, according to Moz, cited in Ranktracker Technical SEO Statistics 2025.
According to Ahrefs, only 33% of all websites pass the Core Web Vitals threshold. Therefore, two-thirds of sites have fixable performance failures sitting in audit reports waiting for someone to deploy the remediation.
What happens to my organic traffic if they get this wrong during a migration?
Site migrations are the single highest-risk event in technical SEO. A wrong redirect map, a missed canonical, or a noindex tag left on staging can remove months or years of accumulated authority. Most technical SEO consultants will tell you that SEO takes 9-12 months to show results. What they do not always tell you is that migration-related losses can take significantly longer to recover from.
A large third-party study of 892 domain migrations found an average recovery time of about 523 days, with 17% of sites never recovering; the primary cause was incomplete or chained redirect maps, not platform choice.
In one documented Volusion-to-Shopify replatform in May 2025, organic clicks fell from roughly 1,200 to 500 per day because long redirect chains were created and critical 301 mappings were missed entirely.
How much do technical SEO companies charge for their services?
The cost of technical SEO services has no industry standard. The same audit scope can cost $500 from an automated tool, $5,000 from a mid-market agency, and $30,000 from an enterprise specialist — and none of those prices is inherently wrong.
What matters is understanding what drives the number, which pricing model aligns incentives correctly, and where the floor is below which quality simply cannot exist, given agency overhead.
Monthly retainer band
Typical agency profile
What it covers
Under $500
Automated package
Tool exports, basic recommendations; no implementation
$500-$1,500
Small generalist agency
Limited hours; broad SEO, light technical focus
$1,500-$5,000
Mid-market agency
Proper technical audits, Core Web Vitals, crawl governance
$5,000-$10,000
Established specialist agency
Deep-dive architecture, JS rendering, migration support
$10,000-$50,000+
Enterprise agency
Full technical stack, log file analysis, dev-embedded workflows
Price is not a guarantee of quality, but if a retainer is below $1,500/month, there are not enough hours in the engagement to do real technical SEO work on anything but the smallest site. If the quote seems unusually low, ask exactly how many hours per month it covers.
Are they set up to keep working as AI search changes what visibility means?
Technical SEO in 2026 is no longer exclusively about Google's ten blue links. Google AI Overviews, Perplexity, ChatGPT, and Gemini all surface content directly in answers, and they rely on structured data, entity clarity, and extractable content architecture to decide what to cite. Technical SEO specialists without a demonstrated approach to AI visibility optimization are building a strategy with a shelf life.
According to Google, pages with properly implemented schema markup appear in rich results 43% more often than pages without structured data, and rich results achieve 82% higher CTR than standard snippets. That gap widens as AI Overviews draw on structured signals.
Traditional technical SEO vs AI-era technical SEO scope
The following table shows what a forward-capable agency scope covers beyond the 2022-era technical checklist.
2022-era technical SEO scope
2025–2026 AI-era scope (required addition)
Core Web Vitals and page speed
Core Web Vitals + LLM extractability (semantic HTML, ARIA)
Crawl and indexation
Crawl + AI crawler rules and structured data for citation engines
Redirect and canonical management
Redirect + entity clarity for brand recognition in AI answers
Schema markup for rich results
Schema + AI citation share tracking across ChatGPT, Perplexity, Gemini
Rankings and organic traffic KPIs
Rankings + brand mention share in AI-generated answers
If a technical SEO company’s scope does not include any mention of AI visibility, structured data for LLMs, or entity optimization, you are paying for a strategy that was current three years ago.
