How to Run a DIY SEO Audit on Your Industrial Website

A DIY SEO audit does not replace a specialist, but it reveals the problems that cost the most and that you can fix yourself. With free tools and half a day, you can walk away with a prioritized findings sheet. Follow the six steps below.

Prerequisites

• Access to your site's Google Search Console and Google Analytics.
• A free crawler, such as the no-cost version of Screaming Frog (limited to a few hundred URLs).
• PageSpeed Insights, which is free and online.
• A spreadsheet with columns: finding, affected page, impact (1 to 3), effort (1 to 3), owner and status.

The six steps

Step 1: check whether Google finds and keeps your pages

In Search Console, open the Pages report. Compare indexed and not indexed and read the reasons. Type site:yourdomain.com into Google for a quick feel of what shows up. Note any important page that is missing from the index.

Step 2: crawl the site

Run the crawler and export 404 errors, redirects, missing or duplicate titles, repeated descriptions and pages without an H1. Each category becomes a row in your sheet, with the number of URLs affected.

Step 3: measure speed and experience

Test five representative pages in PageSpeed Insights, on mobile. Record LCP, INP and CLS and the main suggestions. Heavy images are the most common finding on manufacturer sites.

Step 4: assess the pages that make money

Pick five product or service pages and check: does the title contain the term the customer searches? Are there specifications in text? Is there a clear quote button? Does the content answer real questions? Score each item from 1 to 5.

Step 5: look at queries and what is missing

In Performance, look for queries with many impressions and few clicks, and product terms with no page of their own. These are the fastest growth shortcuts.

Step 6: check trust and local presence

Verify that the site uses HTTPS, shows an address, phone number and company registration details, has a privacy policy, and that your Google Business Profile is complete and consistent with the site.

How to prioritize findings

For each row, multiply impact by ease (3 minus effort, plus 1). Fix first what blocks Google from seeing important pages, then what improves your best-selling products, and last what is cosmetic. For example, 200 URLs with duplicate titles on high-margin products outrank tweaking a description on the about page.

After the audit

Choose five to ten actions and set deadlines two to four weeks out. Log the date of each change and re-crawl afterward to confirm. If the findings call for restructuring the whole site, consider building a new website instead of patching.

Repeat the audit every six months or after any major change. With the previous sheet, you can see what improved and what broke again.

Frequently asked questions

How long does a DIY SEO audit take?

For a small or mid-size site, half a day to a day, including building the findings sheet.

Do I need a paid tool?

Not for a first diagnosis. Search Console, PageSpeed Insights and the free version of a crawler already show the main problems.

When is it worth calling a specialist?

When findings involve migration, restructuring the site or technical issues you cannot fix yourself.
