An SEO crawl report can look overwhelming the first time you open one: rows of URLs, columns of codes and a long list of flagged issues. The trick is knowing which columns matter, which warnings are noise, and how to turn the findings into a short list of fixes in the right order. This guide takes you through a crawl report column by column and gives you a simple scoring method for prioritising what to fix first.

This guide is part of our complete website SEO audit guide, which walks through every step of auditing a small site.

What an SEO crawl report actually shows

A crawler visits your pages the way a search engine bot would: it requests each URL, reads the HTML and records what it finds. The SEO crawl report is that record, usually one row per URL and one column per signal. It answers two questions:

  • Can search engines access and index this page? Status codes, robots directives and canonicals.
  • Is the page clearly described? Titles, meta descriptions, headings and image alt text.

It does not tell you how well a page ranks, how much traffic it gets or whether its content is good. Keep that in mind: a report full of green ticks does not guarantee success, and a report with a few warnings is not a disaster. The LiteScroll SEO Crawler, for example, scans up to 25 pages and flags page titles, meta descriptions, H1 headings, image alt tags, canonical configuration and indexability, then lets you download the results as PDF or CSV.

Start with the summary, not the detail

Most SEO crawl report formats open with a summary: total pages crawled, how many are indexable, and a count of pages per issue. Spend a minute here before scrolling into the rows. Three numbers tell you a lot:

  • Pages crawled vs pages you expected. If you have 40 important pages but the crawler found 12, the others may be poorly linked, blocked or behind JavaScript navigation the crawler cannot follow.
  • Indexable vs non-indexable. A large share of non-indexable pages is either deliberate (archives, tag pages) or a serious problem. Find out which before anything else.
  • The biggest issue count. When one issue affects nearly every page, it is almost certainly a single template or plugin setting, and fixing it clears much of the SEO crawl report in one go.

Reading the report column by column

Read down each column across all pages rather than across each row. Patterns are easier to see, and template problems become obvious when the same issue appears on every page of one type.

ColumnWhat to look forUsually means
Status codeAnything other than 200 on pages you want indexed301/302: redirected; 404: missing; 5xx: server problem
Indexability“Non-indexable” on important pagesNoindex tag, robots.txt block, non-200 status or canonical to another URL
CanonicalEmpty, pointing elsewhere, or pointing at a redirectSearch engines may index a different URL from the one you expect
TitleMissing, duplicate, very long or very shortUnclear topic, truncated search headlines, pages competing
Meta descriptionMissing, duplicate or truncatedSearch engines write their own snippet, often less persuasive
H1Missing, multiple or duplicated across pagesWeak on-page topic signal, often a theme issue
Image altImages with no alt attributeAccessibility gap and lost image context

Status codes and indexability first

These two columns decide whether a page can appear in search at all. A 404 on a page linked from your menu, a 5xx error, or a “noindex” on a service page outranks every other issue in the report. Google’s documentation on how HTTP status codes affect Search explains how each code is treated. If you are unsure whether a page should be blocked or noindexed, our comparison of robots.txt vs noindex clears that up.

Canonicals next

A canonical tag is a hint about which URL should be indexed. In an SEO crawl report, the healthy pattern for most pages is a self-referencing canonical: the canonical value matches the page’s own URL. Problems to flag are canonicals pointing to a different page that is not a true duplicate, canonicals pointing to redirected or 404 URLs, and http canonicals on an https site. Our canonical URL guide covers how to fix each case.

Then titles, descriptions, headings and alt text

These columns are about clarity. Duplicates are the most important pattern to spot: if five pages share the title “Services | Brand”, search engines struggle to tell them apart. Length warnings are softer. A title flagged as slightly long is fine if the important words come first.

Separating real problems from noise in an SEO crawl report

Not every flag in an SEO crawl report deserves action, and treating every warning as urgent is the fastest way to burn out on SEO. Before adding something to your fix list, ask three questions:

  1. Is this page meant to be in search? A missing meta description on a login page, thank-you page or tag archive you have deliberately noindexed is not a problem.
  2. Is the flag intentional? A canonical pointing elsewhere is correct on a printer-friendly or filtered version of a page.
  3. Is the threshold strict? Length limits are guides based on typical display widths, not rules. A 62-character title is not broken.

Common false alarms include redirects you set up on purpose after changing URLs, missing alt text on decorative images (which should have empty alt text), and paginated archive pages that naturally share similar titles.

Quick tip: Open the CSV export in a spreadsheet and filter by one issue at a time. Sorting the URL column at the same time shows instantly whether a problem is limited to one folder, such as /blog/ or /tag/, which usually points to a single template fix.

A simple way to prioritise fixes

Score each issue on two scales from 1 to 3, then multiply:

  • Impact: 3 = stops an important page being indexed or shown correctly; 2 = weakens how an important page is understood or presented; 1 = minor or affects low-value pages.
  • Reach: 3 = affects a whole template or many pages; 2 = affects several key pages; 1 = affects a single page.
IssueImpactReachScore
Noindex on all service pages after a plugin update339
Blog template outputs no H1236
Home page title duplicated on contact page224
Canonical on one old post points to a 404313
Missing alt text on two decorative icons111

Work from the highest score down. When two issues tie, do the quicker one first; momentum matters. This approach keeps you away from the common trap of spending a morning polishing alt text while a noindex tag hides your best page.

Turning the SEO crawl report into a fix list

Write each fix as a single line someone can act on without opening the report:

Page / template | Issue | Fix | Owner | Due
/services/*     | noindex added by plugin | Untick "noindex" in service post type settings | Alex | Today
Blog template   | No H1 | Change post title tag from h2 to h1 in single post template | Dev | This week
/contact/       | Duplicate title | "Contact Us | Brand, Leeds" | Alex | This week

Group template fixes together and hand them to whoever manages your theme. Page-level fixes such as rewriting titles and descriptions can usually be done in your CMS by anyone on the team.

Keep the original export. When you re-run the crawl after making changes, comparing the two SEO crawl report files is the quickest way to confirm fixes landed and nothing new broke.

When to re-crawl and what to compare

  • After every batch of fixes, to confirm they are live (clear any page cache first).
  • After theme changes, plugin updates or migrations, which are the most common sources of new sitewide issues.
  • Monthly, as part of a routine like our 15-minute, 25-page SEO audit.

Compare issue counts per column between crawls. Counts should only go down unless you have added pages. A sudden jump in one column, such as every page becoming non-indexable, is your signal to investigate immediately.

If your site has outgrown a 25-page crawl, or you want a specialist to interpret the findings, the LiteScroll Pro SEO Audit offers a manual review of larger crawls with priority recommendations.

Key takeaways

  • Read an SEO crawl report column by column, starting with status codes and indexability, then canonicals, then on-page elements.
  • Filter out noise: pages not meant for search, intentional redirects and soft length warnings.
  • Score issues by impact and reach, and fix template-level problems once.
  • Write one-line fixes with an owner and a date, then re-crawl to confirm.
