8 search engine optimisation Evaluation Instruments Examined In opposition to a 400,000-Web page Catalog (2026)

At 400,000 SKUs, you don’t select search engine optimisation evaluation instruments by what they discover. You select them by whether or not you possibly can dimension them earlier than you signal. The constraint is arithmetic: six folks, two engineering sprints 1 / 4, natural search driving a 3rd of income. A crawler that surfaces 60,000 points we will’t ship towards returns nothing.

Scale adjustments the query. Google’s personal documentation treats 1,000,000 pages as a big website and 10,000 as medium or bigger, so crawl allocation is a funds. Throughout the thirty outcomes for search engine marketing evaluation instruments, enterprise search engine marketing instruments and ecommerce search engine marketing instruments, not one web page publishes a web page ceiling, a month-to-month crawl allowance, an export row cap or an API charge restrict. The top time period belongs to free one-URL scanners, and the comparisons that exist evaluate options.

SE Rating is the one I’d put within the ticket. It’s the one device right here that publishes the month-to-month web page allowance for every plan, alongside a charge restrict of as much as 10 requests per second. Each tier carries API entry. If faceted URL explosion is your catalog’s actual constraint, Audisto solutions it extra immediately: it meters crawled HTML pages and complete URLs as two separate limits.

These are the columns a 400,000-page purchaser can’t skip earlier than procurement. For ecommerce search engine optimisation instruments, the ceiling column decides it: catalog defects are template defects, copied throughout itemizing URLs a crawl by no means reaches.

Baymard, reviewing 170+ websites and 21,000+ parameters, discovered 58% of desktop and 78% of cellular ecommerce product lists charge poor-to-mediocre, and 51% don’t present all 5 important filter sorts.

How Do You Learn This Desk Earlier than Procurement?

Each determine within the desk was learn from the seller’s personal revealed pricing or documentation on 17 September 2026; nothing was estimated. search engine optimisation evaluation instruments publishing no value aren’t ranked, simply coated under.

5 assessments for an enterprise search engine optimisation platform:

1. Does one full cross match the month-to-month allowance?






2. Does the location audit device’s per-crawl ceiling clear the catalog?






3. Can points be lower by URL sample?






4. Does the search engine optimisation evaluation report attain a scoring sheet on a schedule?






5. What does appearing on a discovering value in sprints?

Gary Illyes, Analyst on the Google Search Relations crew, calls faceted navigation by far the commonest supply of overcrawl points.

One cross is one full crawl, and search engine optimisation evaluation instruments type themselves on whether or not it suits the allowance. Google’s rendering service caches sources for as much as 30 days no matter caching directives these sources set, making JS rendering a sizing column.

1. SE Rating

SE Rating is an enterprise search engine optimisation platform publishing the ceilings a 400,000-page catalog will get sized towards.

Greatest for: companies and in-house groups auditing catalogs of 250,000 to 1,000,000 pages.

Standout function: Development crawls as much as 1,000,000 pages in a single venture and carries 2,000,000 Web site Audit pages a month. That’s 5 full passes of a 400,000-page catalog on our personal arithmetic, with nothing left for re-crawls or competitor audits. The allowance resets month-to-month and doesn’t carry over.

Execs:

• Renders JavaScript inside Web site Audit, and caps crawls by pages, depth, requests per second and redirects.






• Feeds a scoring sheet with out a tier improve: the API and MCP ship on the entry plan.






• Exports any search engine optimisation evaluation report part as XLS or CSV, and takes a TXT or CSV URL checklist as a supply.

Cons:

• Points arrive grouped by kind and severity, so your analyst builds the template view from exports.






• Development’s per-project most is 1,000,000 pages, a unique quantity from the month-to-month allowance, and the one a rising catalog should clear.

Pricing: Core $129 a month ($103.20 yearly), Development $279 a month ($223.20 yearly). A 14-day trial carries 100,000 API and MCP credit.

Price a dash: Sure, on Development. It’s the one entry right here I might dimension earlier than signing, and the per-project ceiling clears 400,000 pages with room. Price range half a dash for an analyst to construct the sample view off the export. Core received’t maintain a single full cross.

2. Audisto

Audisto is a German crawler priced on crawled HTML pages, metering complete URLs individually.

Greatest for: catalogs the place aspect URLs outnumber merchandise.

CommercialPromote Right here

Standout function: The opposite search engine optimisation evaluation instruments right here meter one quantity. Audisto publishes two. On the 500,000-HTML-page step, a single crawl covers 500,000 HTML pages and 15,000,000 complete URLs. A catalog with 400,000 merchandise behind hundreds of thousands of aspect URLs sizes each halves.

Execs:

• Contains JavaScript on each tiers.






• Ships limitless API, exports and seats.






• Cuts every crawl into 70 segments.

Cons:

• Jumps from 250,000 to 500,000, so this catalog buys 100,000 unused pages.






• Retains 4 crawls on the 500,000-page step, limiting comparability.

Pricing: 99 a month at 10,000 pages, 495 on the 500,000 step, revealed with out a forex image.

At catalog scale: Audisto solutions the query a faceted catalog asks, and solutions it on a public web page. I’d put it within the ticket the place aspect URLs outnumber merchandise. The ladder prices 100,000 pages of headroom, and the API charge restrict stays unpublished.

3. Sitebulb

Sitebulb is a desktop and cloud website audit device publishing a ceiling per tier.

CommercialPromote Right here

Greatest for: groups needing the ceiling in writing.

Standout function: Sitebulb states two numbers for each cloud tier: complete URLs a month and most URLs per audit. Small carries 1,000,000 a month with 250,000 per audit; Medium carries 2,500,000 with 1,000,000 per audit. A 400,000-page cross is measured towards each.

Execs:

• Crawls JavaScript at no cost.






• Ranks findings throughout 300-plus hints on Professional.






• Raises desktop Professional’s ceiling to 2,000,000 URLs.

Cons:

• Caps Cloud Small at 250,000 per audit, pushing this catalog to Medium.






• Publishes no API; knowledge travels by MCP or file.

Pricing: Cloud from $125 a month, $495 at Medium; desktop Professional $42, 15% off yearly.

Procurement notice: These numbers dimension a 400,000-page cross earlier than anybody spends a dash. Two issues for the decision: the Cloud FAQ nonetheless names a Massive package deal the desk doesn’t promote, and there’s no cloud trial, so the cross will get confirmed after buy.

4. JetOctopus

JetOctopus is a cloud crawler and log analyser metered by a month-to-month URL pool.

Greatest for: in-house groups operating a number of giant domains.

Standout function: In-Home Professional carries 1,000,000 crawled URLs a month and 5,000,000 log traces, and each tier ships limitless tasks, seats and simultaneous crawls with no per-domain payment. A 400,000-page cross spends 40 per cent of that pool and nothing in licences.

Execs:

• Absorbs a 400,000-page cross with 600,000 spare.






• Provides seats and simultaneous crawls at no cost.






• Segments by regex into template teams.

Cons:

• Meters a month-to-month pool with no per-crawl ceiling, so no run will be sized.






• Publishes no API charge restrict, so integration stays unpriced.

Pricing: In-Home Professional $549 a month billed yearly.

The dash value: Two of the 5 procurement assessments go unanswered right here, and each matter to an engineering lead. You’ll be able to’t schedule a pipeline towards an unpublished charge restrict or plan a full cross towards an unpublished per-crawl ceiling. Price range the invention name.

5. Screaming Frog search engine optimisation Spider

Screaming Frog search engine optimisation Spider is a licensed desktop search engine optimisation crawler with no web page meter.

Greatest for: analysts with provisioned {hardware} and one giant catalog.

Standout function: The ceiling right here isn’t a plan. It’s the machine. 2GB allotted often crawls 100,000 to 1,000,000 URLs, 4GB sometimes reaches 2,000,000, and database storage writes to disk by default. A 400,000-page cross turns into a {hardware} query you possibly can reply in-house.

Execs:

• Crawls with no month-to-month web page meter.






• Renders JavaScript on the paid licence.






• Segments points and compares crawls.

Cons:

• Exposes no vendor API, so exports transfer by hand.






• Ties the ceiling to the machine’s reminiscence.

Pricing: Free to 500 URLs; then GBP 199 per consumer a yr.

Price a dash: It earns a dash the place the {hardware} already exists and the catalog stays below two million URLs. Price range the recurring hour somebody spends shifting exports into the scoring sheet, as a result of no API does it for you. Provision the reminiscence first.

6. Semrush

Most shortlists of search engine optimisation evaluation instruments carry Semrush, which publishes a per-audit ceiling per tier.

Greatest for: mid-market groups auditing below 100,000 pages.

Standout function: Semrush publishes its crawl ceilings in a single place. A Website Audit tops out at 20,000 pages on Starter, 20,000 on Professional+ and 100,000 on Superior, towards month-to-month budgets of 100,000, 300,000 and 1,000,000. Unused allowance doesn’t carry into subsequent month.

Execs:

• Lists a per-audit ceiling and month-to-month allowance per tier.






• Maps three Semrush One plans onto documented toolkit tiers.






• Renders JavaScript from Professional+ upward.

Cons:

• Caps one Website Audit at 100,000 pages, 1 / 4 of the catalog.






• Gates API knowledge integration to Superior, $549.

Pricing: search engine optimisation $139 month-to-month, Starter $199, Professional+ $299, Superior $549.

At catalog scale: 4 hundred thousand pages received’t match one Website Audit on any tier publishing a quantity. At this dimension the route is Enterprise, customized value, a multi-million-page declare with no determine behind it. That’s a gross sales name, not a sizing train.

7. Netpeak Spider

Netpeak Spider is a technical search engine optimisation audit device constructed for throughput, with 100+ severity-sorted points.

Greatest for: analysts operating giant crawls on managed {hardware}.

Standout function: Professional lifts the crawl restrict totally and runs 200 threads. The export aspect matches it: CSV, XLSX and PDF bulk exports protect sorting, grouping and column order, and the seller publishes an export to Google Sheets with none said restrict.

Execs:

• Crawls limitless URLs at 200 threads on Professional.






• Renders JavaScript in free and paid variations.






• Segments crawl knowledge with filters for giant websites.

Cons:

• Ships no vendor API, so nothing reaches a scoring sheet.






• Runs desktop-only, two gadgets per consumer.

Pricing: $20 month-to-month, $193 yearly, $496 lifetime.

Procurement notice: Throughput and portability are actual right here. What’s lacking is the pipeline: with no vendor API, crawl deltas attain a scoring sheet solely when any individual exports them, and the ceiling is one analyst’s machine. Value that export step into each dash.

8. Google Search Console

Google Search Console is Google’s report of a verified property: it publishes what Search did and crawls nothing.

Greatest for: checking a paid crawler towards Google’s indexing report.

Standout function: One Search Analytics request returns 1 to 25,000 rows and defaults to 1,000, paged from a zero-based row. Google provides that the API “doesn’t assure to return all knowledge rows however slightly prime ones.” Sampling is revealed up entrance.

Execs:

Cons:

• Caps URL Inspection at 2,000 queries a day per website.






• Names instance URLs in its indexing reviews and withholds the total set.

Pricing: Free at any catalog dimension.

The dash value: That is our personal arithmetic, and Google publishes no determine prefer it: at 2,000 inspections a day, one cross over 400,000 URLs takes 200 days. Run it beside the search engine optimisation evaluation instruments you pay for. Price range no dash for it.

5 of 13 search engine optimisation evaluation instruments publish no value: Lumar, Botify, Oncrawl, Conductor Web site Monitoring and Ryte, 38% of the roster. Ryte meters on month-to-month periods.

Conductor pairs a 500,000-page monitoring ceiling with a 25,000-page evaluation ceiling on one unpriced tier. Oncrawl publishes solely multipliers: one token per URL, three for a JavaScript crawl. By our personal arithmetic, that’s 1,200,000 tokens for a 400,000-page JavaScript cross, unpriced. Maria Georgieva, who heads search engine optimisation at Payhawk, instructed Search Engine Land: “I at all times start my analysis on the pricing web page.”

• If repeat passes should match the month-to-month allowance, that’s SE Rating.






• If faceted URL explosion is the issue, that’s Audisto.






• If the ceiling is {hardware} you personal, that’s Screaming Frog.






• If one full cross should match one cloud audit, that’s Sitebulb.

Skip if enterprise search engine optimisation software program publishes no ceiling and no value. You’ll be able to’t dimension search engine optimisation evaluation instruments blind.

Invoice Hunt, President of Bisan Digital, is blunt: “A backlog isn’t progress. It’s an unimplemented intent.” He counts greater than 1,400 tickets over 18 months, none applied. Write the ticket in models a product supervisor can rank: income per template per quarter.

Regularly Requested Questions

How typically do you have to do an search engine optimisation audit?

Run the audit repeatedly on the slice that carries income, and a full cross quarterly. At 400,000 pages, each are bounded by the month-to-month web page allowance your search engine optimisation evaluation instruments publish.

What are the very best instruments for enterprise search engine optimisation?

The most effective enterprise search engine optimisation instruments publish three numbers: a per-crawl ceiling, a month-to-month web page allowance and an API restrict. These determine whether or not your catalog suits, so shortlist search engine optimisation evaluation instruments by that check. Of the eight, SE Rating publishes all three.

What’s a technical search engine optimisation audit?

A technical search engine optimisation audit checks how a website will get crawled, rendered and listed: standing codes, canonicals, inner hyperlinks, web page pace. At 400,000 pages it turns into a template train, so a technical search engine optimisation audit device earns its place by slicing findings by URL sample.
