SEO by Daniel vs All in One SEO

All in One SEO is a WordPress toolkit from the WPBeginner family. It gives you a TruSEO score in the editor, schema controls, redirects and sitemap management. It works from inside the site it is installed on, and it is good at that. SEO by Daniel works from the outside. Drop a domain, get a 0-100 score in about two seconds, and see what the site looks like to a crawler that has no plugin. The difference matters most when the WordPress site is not the whole story. A plugin can only see the site it is installed on, and only through the code it controls.

Where All in One SEO wins

• In-editor TruSEO scoring gives on-page feedback on the post while you write it.
• Schema, redirect and sitemap management built for WordPress, with no external tool needed.
• A free Lite tier, with the WPBeginner ecosystem behind it.
• It prevents on-page problems before publish, which an external crawler cannot.
• Deep WordPress documentation and a large plugin base to lean on.

Where SEO by Daniel wins

• Free no-account scan of any domain, with a 0-100 homepage score in about two seconds.
• Sitemap auto-discovery via robots.txt, nested indexes and gzipped sitemaps, with no plugin required.
• Client-ready scoring: executive summary, issues grouped by severity, CSV export you can resell.
• Published pricing at €19/€49/€99 per month (yearly €190/€390/€790), 14-day trial, no credit card. AIOSEO's Pro price is not published.
• Continuous monitoring independent of the CMS or plugin.
• It audits sites you cannot log into, including a prospect's before you pitch.
• The CSV export works as a standalone deliverable, so you can bill for the audit even when the client keeps their own developer.

A real example

A freelance WordPress developer runs maintenance retainers for 20 client sites, all on All in One SEO. Every editor shows a green TruSEO score, and his monthly checks look clean. Then one client, a five-page law firm, messages to say calls from the website have dropped.

He runs the domain through SEO by Daniel and gets 54. The audit finds a staging noindex tag applied to the whole site during a host migration, a redirect loop on the contact page, and missing schema on the service pages. None of it appears in the editor, because AIOSEO grades the posts, not the server response.

He removes the noindex, fixes the loop, adds schema, and the score moves into the eighties. The client sees the before and after, which makes the maintenance retainer easier to justify. It also gave him a reason to run the same check on every site he maintains. He then runs the same audit across the other 19 sites and finds two more with leftover staging tags. That batch view is the part a per-site plugin cannot give him. The workflow is close to the one described for Yoast and Rank Math, because the blind spot is the CMS itself, not the plugin. For the checks in order, see the SEO audit guide.

The verdict

| | All in One SEO | SEO by Daniel | |---|---|---| | Where it runs | Inside WordPress | Browser, any domain | | Job | On-page guidance, schema, redirects | External technical audit | | Scope | The site it is installed on | Any site, any CMS | | Instant no-account score | No | Yes | | Entry price | Free Lite; Pro not published | From €19/mo | | Sees server-level noindex | No | Yes |

When to pick which

Pick All in One SEO when you build and maintain WordPress sites and want on-page, schema and redirect control inside the editor. It is a free, mature plugin and it earns its place on any WP site.

Pick SEO by Daniel when you need to audit a site you did not install anything on, produce a scored client report, or check a portfolio in one pass. If the editor is green and rankings still fall, the cause is usually outside the post, and that is where the external audit starts. Most WordPress developers end up running both, because the plugin prevents on-page problems and the audit catches the ones the plugin cannot reach.

FAQ

Does All in One SEO audit the whole site? No. It grades the content and settings of the WordPress site it is installed on. It does not crawl other platforms or catch server-level problems.

Can a green TruSEO score hide a real problem? Yes. A plugin can be satisfied while the site is noindexed, redirecting badly, or slow. Those issues sit below the editor.

Can I use both? Yes. They work at different layers. Keep AIOSEO for on-page work and run SEO by Daniel for the outside view.
