SEO and Marketing Audit Tools: The Complete Guide

A consultant in Hamilton took on a dental clinic in March. Before the kickoff call she did what most of us do: crawled the site, opened Search Console, screenshotted the homepage score in PageSpeed Insights. She quoted a six-week engagement at $4,800.

Three weeks in, the clinic dropped out of the local results it had ranked in for two years. A page builder update had left a canonical tag on every service page pointing at the homepage. Fixing it took twenty minutes. Winning the trust back took four months, and the $2,000 monthly retainer that should have followed never arrived.

She owned four tools and paid about $300 a month for them. Software was never the problem. Order was. She read the tools in whatever sequence the tabs opened in, and the one signal that mattered sat in a report she never reached.

That is the ordinary failure of audit work: too much data, no fixed sequence. Here is the sequence I would use instead, tool by tool, with what each one answers, how to run it, and what a normal result looks like so you can tell a real problem from noise.

An audit is a fixed list of checks, not a subscription

An audit is a set of checks with a threshold attached to each one. Canonical tags point at themselves or at a real duplicate. Title tags are unique per URL. Largest Contentful Paint is under 2.5 seconds at the 75th percentile of real visits. If a check has no threshold, it is an opinion, and opinions do not belong in a client document.

Build the list once and run the same list every time. The value you sell is comparability: a client can put March next to June because the checks did not change between them.

Where the standard advice goes wrong

The first correction: you do not need a paid stack to audit a site under a few hundred pages. Search Console, PageSpeed Insights, one crawler on a free tier and a spreadsheet will find most of what actually moves rankings or loses leads. I have watched $79 a month subscriptions expire unused on sites with eleven pages.

The second correction: a high site health score does not mean the site is healthy. A crawler scores only what its own checks measure. Ahrefs, Semrush and Screaming Frog each define health differently, and none of them knows whether the page answers the question the searcher typed. A site can score 96 and still be invisible, because the problem is the offer, not the markup. Treat the score as a to-do list, never as a result.

The tools, in the order I would run them

1. Google Search Console

What it answers: what Google indexed, what it chose to show, and what people clicked.

How to use it: open the Pages report first, filtered to not indexed, with the reason column visible. Then Performance, last three months compared with the previous period, sorted by impressions rather than clicks. Then Core Web Vitals, mobile report first.

What to expect: a handful of exclusions that are fine, such as tag pages and parameters, and one or two that are not, such as a whole template returning soft 404s. Expect impressions rising while clicks stay flat on informational pages, which usually means your titles are being outbid by better snippets rather than that demand has gone.

The table worth sending a client is the query list filtered to page two positions. It is the cheapest growth conversation you will have all month.

2. Google Analytics 4

What it answers: what happened after the click, and which channels produced enquiries rather than sessions.

How to use it: mark one primary conversion per page template. A lead form, a call click, a booking. Then read Traffic acquisition by session source, and Landing page by conversion rate. Ignore engagement rate until you have looked at those two.

What to expect: a long tail of channels with zero conversions and two or three that carry everything. Expect direct traffic to hold your best converting pages, because people who already know you type your name.

3. PageSpeed Insights

What it answers: how the page behaves for real users, and what is slowing it down.

How to use it: read the field data at the top before anything else. That section is the Chrome User Experience Report, real visits from the last 28 days. The lab data underneath is one simulated visit from a data-centre machine. If field data is missing, the page does not have enough traffic and the lab score is all you have.

What to expect: field data worse than lab data on mobile, almost always. The usual causes are a hero image served at 3,000 pixels wide, a render-blocking web font, and third-party scripts added by marketing after the site launched.

4. One crawler, not three

What it answers: duplicate titles, orphan URLs, redirect chains, and the internal linking problems Search Console only hints at.

How to use it: Screaming Frog's free tier covers 500 URLs, which is enough for most local sites. Crawl with JavaScript rendering off first, because that is what many tools and some crawlers see. Then check titles, H1s, canonicals, and internal links per URL sorted ascending.

What to expect: a handful of pages with one internal link. Fix those before anything else, because a page nobody links to is a page nobody ranks.

5. Google Business Profile and the local pack

What it answers: whether you appear for the searches that produce a map rather than a list.

How to use it: search the main service plus the city in a private window on a phone using mobile data, then repeat from three nearby postcodes. Note who appears, and whether they have reviews from the last 30 days.

What to expect: the same three businesses, two of which are not the best in the category. Proximity and primary category explain more of it than most owners expect.

6. Google Trends

What it answers: whether a keyword is growing or dying, and whether a season is real.

How to use it: compare two or three head terms, region set to the service area, past five years. Check the seasonality view before you promise a summer campaign.

What to expect: flat or declining volume for most local service terms, with sharp seasonal spikes. That is useful, because it tells you when to publish rather than whether to bother.

7. Looker Studio

What it answers: nothing on its own. It assembles the answers above into one page a client will actually open.

How to use it: connect Search Console and GA4, then build one page with four blocks: the three numbers that matter with their direction, what changed and why, what you did, and what happens in the next 30 days.

What to expect: reporting time drops from a day to an hour, and clients start replying to the email.

Reporting is the last step of an audit, not the first. Build the page only after the checks have thresholds.

The analytics toolkit file, and how to use it

Google publishes its SEO Starter Guide free. You can read it online and download it as a PDF from the same page: Google Search Console SEO Starter Guide.

How to download and use it: open the page, use the download control to save the PDF, and then read only the sections that match the checks above. Do not read it end to end. Keep it as the reference you quote in client documents, so a client can check your claim against Google's own words instead of your opinion. When someone asks why a canonical tag matters, you send the page, not a paragraph.

The rest of the stack can stay free for a long time:

• PageSpeed Insights for field and lab performance.
• Search Console for indexing and queries.
• Screaming Frog SEO Spider free tier for crawls up to 500 URLs.
• Google Trends for demand and seasonality.
• Looker Studio for the single report page.

What to stop paying for

Do not buy two tools in the same category. One crawler, one rank source, one dashboard. Daily rank tracking on a five-page site is not data, it is a notification you will learn to ignore. And do not buy an AI audit PDF that produces a hundred recommendations in ten seconds: a hundred items is not a priority list, and a client who receives one learns that your judgement is a machine's.

Where to start today

Open the Search Console Pages report, export every URL that is not indexed, then run one crawl and sort by internal links ascending. Fix the URLs that are both. That single afternoon resolves more than a year of stacking subscriptions.

Key takeaways

• Run the same checks in the same order every time; consistency is what makes two audits comparable.
• A site health score is a to-do list, not a verdict, because no crawler knows whether a page answers the query.
• Search Console queries sitting at position two are the cheapest growth conversation you will have each month.
• Keep the stack free until you can name the check a paid tool passes and a free tool fails.

A Webcheckhub audit scores the same areas in one pass, covering indexing, page performance, social consistency, technical SEO health and conversion readiness, so you can see the whole picture before you decide what to pay for. If you would rather have that audit run for a client end to end, Solutions Elites does exactly that at solselites.com.
