Search Console diagnostics for maritime sites: 8 things to check monthly

For a free tool, Search Console is the most underused asset on the average maritime marketing stack. Teams open it once a quarter, glance at the performance graph and close the tab, then wonder why issues only surface when traffic has already dropped. A disciplined thirty-minute monthly review catches most problems weeks before they show up in pipeline.

Eight checks, in order, that should be a monthly habit on any maritime site that takes search seriously.

1. Coverage report: indexation health

Open the Pages report. Look at:

• “Not indexed” pages. Numbers under 100 are fine. Numbers over 500 mean either you have a thin content problem or your CMS is generating pages nobody asked for (tag pages, paginated archives, low-value taxonomy URLs).
• “Indexed but not in sitemap”. These are pages Google found but that aren’t in your sitemap, often soft-launched pages or development URLs that escaped.
• “Discovered, not indexed”. These are pages Google knows about but hasn’t bothered to crawl. Usually a quality signal: Google thinks they’re not worth indexing.

Each category needs a ten-minute investigation, not just acknowledgement.

2. Performance report: query movement

Filter the last 28 days vs the previous 28. Look for:

• Queries that have dropped position by 5 or more places (early sign of a content or technical issue on a specific page)
• Queries that are trending up and could be reinforced with internal linking or related content
• New queries appearing in the top 50 (these are signals of where Google is starting to understand your content)

Don’t obsess over rank fluctuation in positions 20-50; it’s noisy. Focus on top-20 movement, where the commercial value is.

3. Core Web Vitals report

Open the Core Web Vitals report, segmented by mobile and desktop. The bar is 75% of visits hitting “Good” on each metric. Look for:

• Templates that have slipped from “Good” to “Needs improvement”
• New URLs appearing in the “Poor” bucket (usually a recently-launched page with unoptimised images)
• Patterns by template (if all your service pages are slow, the issue is template-level)

Maritime sites often regress when the marketing team uploads a 5MB hero image to the new case study page without compression.

4. Mobile usability

Less critical than it was when it was a separate report, but still worth a monthly glance for:

• Tap targets too close together
• Text too small to read
• Content wider than the screen

These regressions usually appear after a CMS template tweak by a developer who only tested desktop.

5. Sitemaps report

Confirm the sitemap is being read (last fetched date should be within the last week). Confirm the URL count matches what you expect. If the count has dropped, something is excluding pages from the sitemap that shouldn’t be excluded.

6. Manual actions and security issues

Both should always be empty. If they aren’t, treat as urgent. Manual actions on a maritime site are rare but devastating; security issues can mean your site has been compromised, which is more common than maritime brands assume.

7. Links report: top linked pages

Look at the top 10 linked-to pages. Are they your priority commercial pages? Or are they old news posts and PDFs? If your most-linked pages are not your commercial pages, you’re missing internal linking opportunities to redistribute that authority.

Look at top linking domains. Watch for new mentions from trade press (TradeWinds, Lloyd’s List, Splash) appearing here, often before your PR team notices. Watch for unexpected domains; sometimes these are negative SEO attacks (rare) or content scraping (more common).

8. International targeting (if applicable)

For sites with hreflang, the International Targeting report shows hreflang errors. Watch for:

• “Missing return tags” (your en-GB page references en-SG but en-SG doesn’t reference back)
• Invalid language/region codes
• Cluster size mismatches

If hreflang is broken, Google ignores it and serves whatever page it thinks fits, which is usually wrong.

What to do with the findings

A useful monthly Search Console review produces a short list of action items, not a 20-page report. Three to five items per month that need a developer or content fix. Most months on a healthy maritime site, the list will be:

• One template-level performance issue to fix
• Two pages with unexpected ranking drops to investigate
• One indexation pattern to clean up
• One internal linking opportunity to take advantage of

If your monthly review is producing more than five items, you have either a recently-migrated site or a neglected one. Both need a proper audit, not just monthly check-ins.

The teams that build durable maritime SEO are the teams that catch issues in Search Console before they become visible in pipeline reports. Thirty minutes a month is a tiny investment for that signal.
