Scalable processes

As our site scaled past 50k pages, DiagnoSEO automated checks for redirects, canonicals, and thin content. Their scalable process gave us confidence we wouldn’t be blindsided as we grew.

Crawl depth optimization

DiagnoSEO restructured navigation so important pages weren’t buried four clicks deep. Crawl budget improved and impressions grew. It’s the kind of technical fix you don’t see immediately but pays dividends long term.

Link building that feels natural

Their outreach focused on relevance, not volume. The placements look authentic, and our brand credibility improved. Traffic from referring domains is a bonus. Finally an agency that avoids shortcuts.

Analytics cleanup

Our GA4 was a mess. DiagnoSEO configured events, set up conversion tracking, and aligned SEO goals with business KPIs. Now we can clearly see which organic pages actually drive revenue.

Collaboration with dev team

DiagnoSEO didn’t just drop a report—they worked side by side with our developers, joined sprint planning, and verified fixes in staging. That partnership made execution seamless and ensured nothing slipped through.

Good audits, slower link outreach

The audit phase was excellent, but link building outreach took longer than expected to show results. Once links landed, impact was clear. Deducting one star for pace, not quality.

Content gap analysis

Their gap analysis revealed dozens of queries competitors ranked for that we didn’t target. We built content accordingly and captured that traffic. It felt like unlocking hidden demand with a clear blueprint.

Realistic expectations

What I liked most is they never promised instant rankings. They set milestones, explained volatility, and showed progress. It took patience, but the trust paid off with durable growth.

On-page polish

DiagnoSEO went page by page improving titles, headings, and internal links. Bounce rates dropped and average time on page increased. It’s amazing how small optimizations across the board add up.

Penalty recovery

We had a manual action due to spammy backlinks. DiagnoSEO audited our link profile, disavowed toxic domains, and built a recovery plan. Within months, traffic was back and stronger. Their calm guidance saved us.

Long-term mindset

They emphasize durable rankings over temporary tricks. Seeing stable growth across volatile algorithm updates proved their method works. It takes time, but the sustainability is worth it.

Good but communication lagged

The technical recommendations were spot-on, but sometimes emails took a couple of days to answer. Once we got on weekly calls, the collaboration was smoother. Still very happy with results and giving 4 stars.

International SEO expertise

We run sites in 5 languages. DiagnoSEO corrected hreflang tags, consolidated duplicate signals, and built localized keyword maps. Rankings improved in every market, and we finally have clarity on cross-domain cannibalization.

Clear prioritization

Our site had hundreds of issues. DiagnoSEO grouped them into critical, medium, and low priority. That clarity helped our devs move fast. The most critical fixes alone delivered noticeable SEO lift. Excellent project management.

Data-driven approach

Everything they recommend is backed by data—logs, crawl analysis, or competitor benchmarks. No fluff. That made it easy to convince stakeholders. Organic traffic from non-brand keywords grew steadily month after month.

Local SEO improvement

Our service business relied on map pack rankings. DiagnoSEO optimized Google Business Profile, citations, and local content. We now show up in the top 3 for “near me” searches across multiple districts. The phone actually rings more.

Structured data expertise

We needed schema help for products and FAQs. DiagnoSEO implemented JSON-LD, validated with Google tools, and monitored impact. Rich snippets now appear for dozens of pages, boosting click-throughs. Highly recommend their technical SEO service.

Competitor insights are gold

DiagnoSEO mapped competitor backlink strategies and highlighted gaps we could realistically close. Their outreach plan was targeted, and the links we gained were from genuinely relevant sites. Our domain authority rose and referral traffic improved.

Solid but took time

The audit and recommendations were strong, but we underestimated internal dev resources needed. It took longer than expected to implement fixes. Once changes were live, however, rankings and conversions rose. I give them 4 stars for pacing, 5 for quality.

Strong partner for startups

As a startup with limited budget, we needed maximum impact. DiagnoSEO focused on technical hygiene and a handful of high-intent pages. The results were quick and measurable. We’ll expand scope as we grow.

Quick technical wins

They solved indexing issues that plagued our blog for years. With redirects, canonical fixes, and sitemap cleanup, 200+ articles reappeared in search within weeks. It was the fastest ROI we’ve seen.

Transparent reporting

Unlike other agencies, DiagnoSEO shows exactly what work is being done each month. Their dashboard highlights ranking movements, traffic by intent, and technical issues resolved. We finally feel confident knowing what we pay for is moving the needle.

Thorough SEO audit

We brought DiagnoSEO in for a site audit and were amazed by the detail. They uncovered duplicate content, broken schema, and crawl traps. The report included clear steps and priority levels. Implementing even half the fixes gave us a traffic jump within a month. Their team explains complex issues in plain language.
