OnPage Agent vs OTTO SEO. Real edits, not a script.
Both find on-page SEO problems and fix them for you. The big difference is how: OTTO applies its fixes through a JavaScript pixel, while OnPage Agent writes them into WordPress itself.

How they compare.
| OTTO SEO | OnPage Agent | |
|---|---|---|
| How fixes are applied | A JavaScript pixel added to your site (for example through Google Tag Manager) changes pages as they load | A WordPress plugin writes changes into your posts, pages and SEO fields |
| Where changes live | In the pixel’s runtime layer, not in your CMS | In WordPress: the same place you’d edit them by hand |
| If you remove it | Fixes delivered by the pixel stop appearing | Content edits stay; you can still roll back while the plugin is installed |
| What crawlers see | Fixes need JavaScript to run; crawlers that don’t render it may miss them | Fixes are in the HTML from the server, for every crawler |
| Platforms | Any CMS that can load the pixel | WordPress |
| What it fixes | Meta tags, headings, alt text, internal links, canonicals, schema and more | Titles, descriptions, canonicals, headings, alt text, internal links, schema, redirects, sitemaps and 15 speed optimizations |
| Control | Automated deployment of supported fixes | Suggest, Autopilot or Autonomous modes, approvals by risk, protected pages |
| Undo | Managed in the Search Atlas dashboard | Exact rollback of any single change from the change log |

Questions about switching.
Is OnPage Agent a good OTTO SEO alternative?
If your site is on WordPress and you’d rather have fixes written into your site than applied by a script at page load, yes. If you need one tool for many non-WordPress sites, OTTO’s pixel approach covers more platforms.
Can I use both?
We don’t recommend running two tools that edit the same titles and tags at once. If you switch, turn off OTTO’s on-page fixes first, then let OnPage Agent audit the site and write the fixes into WordPress.
Will my OTTO fixes carry over?
Fixes applied through a pixel aren’t stored in WordPress, so they won’t carry over on their own. OnPage Agent’s first audit finds the same issues again and prepares fixes that live in your content.
