QUICK ANSWER
A technical SEO audit in Bangkok costs ฿15,000–฿80,000 depending on scope. Monthly SEO management runs ฿40,000–฿150,000/month for serious technical work. Anything under ฿10,000 is an automated report, not a real audit. What follows is a full breakdown of scope, pricing, and what to watch out for.
Most Bangkok SEO agencies don't publish their prices. We do. This guide breaks down what an SEO audit actually covers, what ongoing management should cost, and the red flags that separate real technical work from monthly reports dressed up as SEO.
An SEO audit identifies technical problems blocking your rankings. The word "audit" covers a wide range — from a 5-minute automated Screaming Frog run to a multi-week forensic analysis of your crawl log, JS rendering, and schema graph. Price correlates directly with depth.
What's always included in a real audit: written prioritised fix list with code-level examples, estimated ranking impact per fix, and a follow-up call to walk through findings. If an agency delivers a PDF and disappears, it's not an audit.
Monthly SEO retainers in Bangkok cover ongoing implementation, monitoring, and iteration. The biggest mistake buyers make is comparing apples to oranges — a ฿15K/month retainer that's "content writing + keyword reports" is not the same as a ฿70K/month retainer that's engineering-led technical SEO with real schema deployment and crawl-budget management.
Right for: new sites needing content volume. Wrong for: sites with technical problems or competitive verticals.
Right for: competitive markets, e-commerce, multilingual sites. This is what SEO Agency Bangkok delivers.
We publish our actual rates because we believe transparency builds trust. Our pricing is based on scope, not arbitrary tiers.
Below is the complete scope of what a proper technical SEO audit should cover. Use this as a checklist when evaluating Bangkok agencies. If an agency's audit doesn't cover these areas, ask why.

Log files show exactly what Googlebot crawled, how often, and what it ignored.
We've audited sites previously managed by Bangkok agencies. Here are the patterns we see repeatedly.
No credible SEO agency guarantees specific positions. Google's algorithm is outside anyone's control. This is the number-one sign of black-hat or low-quality work.
If the agency sends a PDF report every month but never edits your site, you're paying for monitoring, not SEO. Real SEO requires code changes: meta tags, schema, internal links, structured data.
If an agency has never asked for your server logs, they don't do technical SEO. Log files are the ground truth of what Google is crawling. Without them, you're guessing.
Rankings fluctuate. Organic traffic, organic conversions, and crawl budget utilisation are more meaningful metrics. Agencies fixated on position reporting are often the ones gaming vanity rankings on low-traffic keywords.
Private Blog Networks violate Google's guidelines and can result in manual penalties. Any agency offering bulk backlinks for ฿5,000/month is running a PBN. These work short-term and cause long-term damage.
Both models work. For sites with clear technical problems, a one-time audit + fix project makes sense. For ongoing competitive markets (fintech, hospitality, SaaS), monthly retainers maintain and build on gains. Most serious engagements at SEO Agency Bangkok start with a one-time audit (฿35K–฿60K), then move to monthly management after findings are clear.
For technical fixes (Core Web Vitals, crawlability, schema), you can see GSC improvements in 2–6 weeks. For competitive keyword ranking improvement, 3–6 months is realistic. For new domains in competitive verticals, 6–12 months. Anyone promising results faster is using tactics that either won't stick or will trigger penalties.
Our clients typically see organic traffic increases of 40–220% within 6 months of full technical implementation. For a B2B site generating 10 leads/month from organic, a 100% improvement to 20 leads/month — even at a modest ฿50K average deal value — represents ฿500K/month in new pipeline. The ฿50K–฿80K/month retainer cost is low relative to that output.
Local SEO targets geographic queries ("seo agency Bangkok", "furniture store Bangkok") via Google Business Profile, local schema (LocalBusiness, address, geo coordinates), and local citations. Technical SEO is about the underlying architecture that affects all organic visibility. For most Bangkok businesses, both are needed: local schema ensures geographic relevance, technical SEO ensures the site is properly indexed and fast.
