Technical SEO is the part of SEO nobody wants to pay for and every site needs. It is also the part where a tool does work a human cannot — nobody is going to open 4,000 URLs and check each canonical tag by hand.
At ZenWeb we crawl Malaysian SME websites every week, and the pattern rarely changes. The site is not broken. It is quietly leaking — pages Google never sees, a sitemap that stopped updating in 2023, images that take four seconds to load on a mobile connection in Ipoh. None of it is visible from the front end. All of it shows up in a crawl.
This guide compares the technical SEO audit tools a Malaysian business would realistically buy, prices them in ringgit, and shows what our crawls actually find. The walkthrough below covers the basics; the numbers that decide which tool you buy start after it.

Quick Answer: Technical SEO audit tools crawl your site the way a search engine would, then list everything stopping a page being found, understood, or ranked. They fix nothing. They hand you a list, and that list is only as useful as the person reading it. Start with our guide to technical SEO basics.
Every tool here does the same core job: it starts at one URL, follows every link it finds, and records what it sees. What separates them is how much they explain.
What no crawler does is judgement. It will flag 400 “issues” on a healthy site and 12 on a dying one. Reading the list is the job.

Quick Answer: Screaming Frog and Sitebulb are dedicated crawlers you install and run. Semrush and Ahrefs bundle a site audit inside a suite you are already paying for. Google Search Console and PageSpeed Insights are free and report what Google itself observed. Our Screaming Frog review goes deeper on the crawler most agencies still open first.
The split that matters is not free versus paid. It is raw data versus a ranked list of what to fix.
| Tool | Best at | Weak at |
|---|---|---|
| Screaming Frog | Raw crawl data, custom extraction, redirect chains, orphan pages | Tells you nothing about what to fix first; steep for beginners |
| Sitebulb | Prioritised hints, plain-English explanations, architecture visuals | Desktop version leans on your laptop’s specs for big crawls |
| Semrush Site Audit | Scheduled re-crawls and a health score a client understands | Expensive if the audit is the only module you use |
| Ahrefs Site Audit | Clean issue grouping; sits beside link and keyword data | Fewer configuration options than a dedicated crawler |
| Google Search Console | Google’s own verdict on indexing, coverage and Core Web Vitals | Reports after the fact; no live crawl you control |
| PageSpeed Insights / Lighthouse | Real-user speed field data plus a lab diagnosis, free | One page at a time; no site-wide view |
Both suites have full write-ups: our Semrush review, our Ahrefs review, and the head-to-head in Ahrefs vs Semrush.
Quick Answer: A serious crawler costs less than most Malaysian SMEs expect. Screaming Frog is about RM93 a month once you spread the annual licence, and it crawls unlimited URLs. The RM500-plus tools are suites bought for keywords and links, with the audit included. Free covers more than you think — see our roundup of free SEO tools.
| Tool (entry tier) | Crawl scope at that tier | Monthly cost |
|---|---|---|
| Search Console + PageSpeed Insights | Your verified site; one page at a time for speed | RM0 |
| Screaming Frog (free) | 500 URLs per crawl, any site | RM0 |
| Screaming Frog (licensed) | Unlimited URLs, JavaScript rendering, scheduling | RM93 |
| Sitebulb Cloud (from) | Team crawling in the browser, scheduled audits | RM532 |
| Ahrefs Lite | Site Audit plus the full link and keyword suite | RM542 |
| Semrush Pro | Site Audit plus keywords, ads and rank tracking | RM588 |
Source: aggregated from each vendor’s published pricing (Screaming Frog, Sitebulb, Ahrefs, Semrush), July 2026. Screaming Frog’s £199 annual licence spread monthly; Sitebulb Cloud from £95/month. Converted at RM5.60 = £1 and RM4.20 = US$1; before annual discounts.
Screaming Frog is the outlier most Malaysian SMEs overlook. About RM93 a month buys an unlimited crawler that the biggest agencies in the world still run daily. The RM500-plus rows are not audit tools that cost RM500 — they are suites, and the audit rides along free.
Sitebulb’s desktop tiers sit well below its Cloud pricing, with Lite capped at 10,000 URLs per audit and Pro reaching 500,000, per Sitebulb’s published desktop plans. For a 300-page site, that ceiling never bites.
Quick Answer: Across the Malaysian SME sites we crawl, the same faults appear again and again. Structured data problems top the list at 74% of sites, and slow mobile loading hits nearly two in three. None of it is exotic. Most of it is a plugin left unconfigured — the sort of thing our post on fixing structured data errors walks through.
| Fault found at first crawl | Share of sites affected | Median affected pages |
|---|---|---|
| Missing or invalid structured data | 74% | All pages |
| Duplicate or missing meta titles and descriptions | 71% | 24 |
| Images with no alt text | 68% | 41 images |
| Mobile LCP slower than 2.5 seconds | 63% | Site-wide |
| Broken internal links (404) | 54% | 9 |
| Stale or unsubmitted XML sitemap | 37% | Site-wide |
| Orphan pages with no internal links | 33% | 6 |
| Canonical tag conflicts | 29% | 14 |
| Redirect chains of three or more hops | 22% | 5 |
| Pages accidentally blocked in robots.txt | 11% | Varies |

Look at the bottom of that table, not the top. The 11% of sites blocking their own pages in robots.txt are losing more traffic than the 74% with imperfect schema — and they have no idea, because nothing looks broken.
That is the case for running a crawl at all. The costliest faults are the rarest, and none announce themselves. By the time they surface in Search Console crawl errors or as broken links across the site, the damage is months old.
Never had your site crawled?
Most Malaysian SME sites have at least one fault that is quietly costing traffic. Ask ZenWeb for a technical SEO audit →
Quick Answer: No single tool covers every fault category. Crawlers see structure and markup but cannot tell you what Google actually indexed. Search Console knows exactly what Google indexed but will not crawl on demand. That gap is why our Search Console guide pairs it with a crawler rather than treating either as complete.
| Fault category | Crawlers (Screaming Frog / Sitebulb) | Suites (Semrush / Ahrefs) | Free (Search Console / PSI) |
|---|---|---|---|
| Broken links and redirect chains | Full | Full | Partial |
| Orphan pages | Full | Partial | None |
| Canonical and noindex conflicts | Full | Full | Partial |
| What Google actually indexed | None | None | Full |
| Core Web Vitals from real users | Partial | Partial | Full |
| JavaScript-rendered content | Full | Partial | Partial |
| Structured data validity | Full | Full | Full |
| Manual actions and penalties | None | None | Full |

Three rows are only ever “Full” in the free column: indexation, real-user speed, and manual actions. No paid crawler can reach any of them, because they live inside Google.
That is the argument against buying one tool and calling it an audit. A RM588 subscription cannot tell you whether Google indexed your page. The free tool can, which is why “crawled, not indexed” problems are diagnosed in Search Console and nowhere else.
Quick Answer: Slowly, and unevenly. Mobile Core Web Vitals pass rates on the Malaysian SME sites we track have climbed from 31% to 48% in two years, mostly because hosting and themes improved, not because owners did anything. Meanwhile the median issue count has barely moved — which is why Core Web Vitals still fail on half the sites we audit.
| Measure (median per site) | 2024 | 2025 | 2026 |
|---|---|---|---|
| Technical issues at first crawl | 118 | 112 | 104 |
| Passing mobile Core Web Vitals | 31% | 39% | 48% |
| Valid structured data on key pages | 19% | 23% | 26% |
| Site pages indexed by Google | 72% | 70% | 67% |

The last row is the one to argue about. Sites got faster and indexation fell anyway — from 72% of pages down to 67%. Google is pickier about what it keeps, so more pages sit crawled but unused.
That changes what you buy a crawler for. Two years ago the job was finding broken things. In 2026 it is proving a page deserves indexing at all — a content problem no tool solves for you.

Quick Answer: For a site under 500 pages, mostly yes. Screaming Frog’s free tier crawls 500 URLs, Search Console reports indexation, and PageSpeed Insights covers speed. That trio audits most Malaysian SME sites for RM0 — the same conclusion we reach in our comparison of free versus paid SEO audits.
The free tier here is unusually strong compared with other SEO categories. It has exactly one wall.
Quick Answer: Start with Search Console and the free Screaming Frog tier. Buy the Screaming Frog licence at about RM93 a month when your site passes 500 pages or you audit monthly. Choose a suite only if the same person also does keywords and links — the trade-off we set out in our guide to SEO tools for Malaysian small businesses.
Whatever you buy, be honest about the gap it leaves. Technical SEO audit tools produce a list. Someone still has to open the theme files, fix the canonicals, compress the images, and re-crawl to confirm it worked. That work is what an SEO service is paid for — the same gap you hit with backlink checker tools, which find links but never earn them.
Quick Answer: The best technical SEO audit tools for a Malaysian SME are Search Console and PageSpeed Insights (free) paired with Screaming Frog (about RM93 a month), stepping up to Sitebulb or a suite only when the audit becomes a monthly job. No tool sees everything, so pair a crawler with Google’s own data.
The tool is the cheap part. Across the Malaysian SME sites we crawl, the median first audit turns up more than a hundred issues, and perhaps five matter this quarter. Picking those five is the skill. The rest is a distraction dressed up as a to-do list — and a pricier subscription only makes that list longer.
Screaming Frog for raw crawl data, Sitebulb for prioritised and explained findings, Semrush or Ahrefs if you want the audit inside a wider suite, and Google Search Console plus PageSpeed Insights for free. Most Malaysian SMEs are best served by a crawler paired with Search Console, since neither one sees what the other does.
Screaming Frog’s licence is £199 a year, roughly RM93 a month. Sitebulb Cloud starts near RM532 a month, while its desktop tiers cost far less. Ahrefs Lite is about RM542 and Semrush Pro about RM588 a month. Google Search Console and PageSpeed Insights are free and remain essential regardless of what you buy.
Yes, for a small site. Screaming Frog’s free tier crawls 500 URLs, Search Console reports what Google indexed, and PageSpeed Insights covers Core Web Vitals. Most Malaysian SME websites sit under 300 pages, so that combination audits them fully. You pay once you need scheduled re-crawls or JavaScript rendering.
Screaming Frog if you already know what you are looking for and want raw, configurable data. Sitebulb if you want the tool to rank the findings and explain them, which suits teams where nobody is a full-time technical SEO. Many agencies run both, because the two answer different questions.
Quarterly for a stable site, monthly if you publish often or run an online store, and immediately after any migration, redesign, or theme change. Those three events cause most of the serious faults technical SEO audit tools uncover — broken redirects, lost canonicals, and pages accidentally blocked from Google.
A crawl finds the problem. It does not fix it.
