LinkOK vs Siteliner (2026): which should you pick?

Pick LinkOK if

• Fits if your site has under 100 pages and a monthly link check is enough
• Works for schools, libraries, nonprofits and open-source projects, which it says it serves free

Look elsewhere if

• Tight if you stay free, at one 100-page scan a month with public reports
• Pricey if your site is big, as daily scans of 100,000 pages are $333 a month billed yearly
• Too light for SEO audits, as it checks links only, with no API or integrations
• Watch out: the terms make every purchase non-refundable, and cancelling takes effect at the term's end

Pick Siteliner if

• Fits if your site is small and you want to find text repeated across its own pages
• Works for occasional bigger scans paid by the page rather than by the month

Look elsewhere if

• Tight if you stay free, at 250 pages once every 30 days per site
• Too light for checking copies on other websites, which is Copyscape's job
• Pricey if you scan big sites often, at 1¢ a page, so $300 for a 30,000-page scan
• Watch out: summary reports are kept for 185 days and page reports for 60

LinkOK

• The free plan scans up to 100 pages once a month, and its reports are public.
• Prices climb with page count and scan frequency: daily scans of 100,000 pages cost $333 a month billed annually ($400 monthly).
• It checks links only; its pages list no on-page SEO, speed or content checks, and no API or integrations.
• The terms say all purchases are non-refundable; a cancellation takes effect at the end of the paid term.

Siteliner

• Siteliner Premium has no subscription: each page scanned costs 1¢, paid from credits bought in advance by card or PayPal.
• The free scan stops at 250 pages and can be run on a site only once every 30 days.
• It checks internal duplicate content only; copies on other websites are the job of Copyscape, a separate service.
• Summary reports are kept for 185 days and highlighted page reports for 60 days.

LinkOK

Scheduled scans

Scans the whole site on a fixed schedule, monthly, weekly or daily depending on the plan, without anyone starting a check.

Email reports

After each scan it sends an email with a summary of the results and a link to the full report.

Retries after temporary errors

Links that fail with a temporary error are checked again before they are reported, to reduce false positives.

Unlimited links per site

Every plan, the free one included, checks an unlimited number of links; the limit is the number of pages on the site.

Public or private reports

Reports on the free plan are public; every paid plan keeps them private.

Tiers up to 100,000 pages

Paid tiers run from 100 to 100,000 pages, and larger sites can ask sales for a bigger plan.

Siteliner

Internal duplicate content

Shows how much of each page's text also appears on other pages, highlights the matching passages, and leaves out menus and other common content.

Broken link check

Checks every internal link and highlights the broken ones on the page where they appear.

Page Power

Scores each page from 0 to 100 by how prominently it is linked from other well-linked pages on the site.

Reports and XML sitemap

Gives a summary of every scanned page, a list of skipped pages with the reason, and a standard XML sitemap of the site.
