Your First 90 Days With an SEO Audit Tool

The week-one mistake

You run the first crawl and get 1,400 issues. The instinct is to start at the top of the list and work down, or to sort by count and fix the biggest category — usually missing alt text, because there are 600 of them.

Both are wrong, and the reason is that issue counts and issue value are almost unrelated. Six hundred missing alt attributes are worth less than one noindex on a template. Volume is a measure of how templated your site is, not how much money is at stake.

Order by consequence instead. The sequence below does that, and the first question is always the same: is this page in the index at all?

Week 1: can engines see it?

Nothing else matters until this is settled. A perfectly optimised page that engines can't index is worth zero, and no amount of title-tag work changes that.

1. Robots.txt. Read it line by line. Look for a Disallow covering something important, and check whether AI crawlers are blocked deliberately or by inheritance — see AI crawlers and robots.txt.
2. Every noindex. List them and justify each one. Auth pages, cart, internal search: correct. A product template, a category, your blog: an emergency.
3. Canonicals. Pages canonicalising somewhere unexpected are asking to be excluded. Canonical tags.
4. Page count sanity check. Does the crawl's total roughly match what you believe you have? A large shortfall means a section isn't linked and isn't being found.
5. Status codes. 404s and 5xx on pages that should work.

This is usually a day or two of work, and it's where the quarter's largest wins live. If the crawl found pages wrongly excluded from search, fix those and stop — you've already justified the tool.

Weeks 2–4: templates

Now sort findings by template rather than by page. Every crawler outputs a page list; the useful transformation is grouping it.

"Missing meta description on 340 pages" is not 340 tasks. It's one template task, or it's a content task on 340 genuinely distinct pages — and which one it is determines whether it takes an hour or a month. Check a few examples from each group before deciding.

What's usually template-level and therefore cheap per page:

• Missing or duplicate titles following a pattern.
• No H1, or multiple H1s, on a whole page type. See H1 tags.
• Missing canonical, or a hardcoded one.
• No structured data anywhere.
• Missing alt attributes where images are rendered by a component.

Ship these in batches and re-crawl after each. Template edits have wide blast radius in both directions — verify the fix landed and nothing else moved.

Month 2: content and AEO

Technical faults are fixed; now the harder work. This month is per-page and doesn't compress, so scope it: your top twenty pages by commercial value, not your whole site.

1. Thin pages that should be substantial. Not every short page is a problem — decide deliberately per page whether it's under-built or correctly brief. Thin content.
2. A quotable lead passage on each of the twenty. Forty to sixty words directly under the H1, self-contained. Highest-return AEO change there is — how to write one.
3. Question-shaped headings. Rewrite section headings as the questions people type. Details.
4. Schema where it's genuinely applicable. FAQPage on pages that already answer questions, Product, LocalBusiness. Don't invent Q&A to justify markup.
5. Internal links to your priority pages. Often the fastest ranking change available. Internal linking.

Expect the AEO score to move more than the SEO score this month. That's the point: by now the SEO side is mostly clean, and a healthy SEO score with a poor AEO score is the normal state of a well-maintained site.

Month 3: make it automatic

The month that decides whether any of this survives. Almost every audit-tool subscription follows the same decay: intense use for six weeks, then nothing, then a cancellation. The cure is removing yourself from the loop.

1. Schedule the crawls. Weekly if you deploy weekly. The frequency question is a risk question — how often to crawl.
2. Turn on alerts, tuned high. Indexability changes, page count drops, new bulk 404s. If they fire constantly you'll ignore them, so raise the thresholds until each one is believable.
3. Book one review session a month. In the calendar, thirty minutes, reading the diff rather than the audit.
4. Write down the baseline. Today's scores and page counts. In six months this is how you'll know whether things drifted.
5. Decide who gets the alert. A shared inbox nobody owns is the same as no alert.

What to ignore in 90 days

Deliberately not on the list, because they cost more attention than they return early on:

• Bulk alt text on decorative images. Real accessibility work, weak SEO return, huge issue count. Do it for the right reason, later.
• Meta descriptions on low-value pages. Fix them on pages that get traffic; the archive can wait.
• Chasing a perfect score. The last few points cost more than the first thirty and are worth less. A site at 90 with correct indexability beats one at 98 with a stray noindex.
• Rewriting everything for AEO at once. Twenty pages properly beats two hundred superficially.
