How this directory works
Every tool on this page is something we use, or used long enough to form an honest opinion. We've run SER Verified Lists since 2013 — long enough to watch dozens of "must-have" SEO tools get hyped, peak, and quietly stop working. The ones above are still standing in 2026, and we re-check prices and offers on each provider's own site before we update this page. Affiliate disclosure: most outbound links are affiliate links. If you buy through them we earn a commission at no extra cost to you, and that's part of what funds the list. Nothing is here because the payout is nice.
Directory questions
About this list
Why these suppliers?
They are the services we pay for and run next to our own verified lists. A supplier only stays on this page while we keep using it.
Are these affiliate links?
Most are. If you buy through them we earn a commission at no extra cost to you. Suppliers marked without one (OpenRouter, Anthropic, DeepSeek, Green Server, Omega Indexer, SER Nuke) link straight to their sites.
How current are the prices?
Every price was re-checked on the supplier's own site on 2 October 2026. Each card names its source. Suppliers change prices and run coupons often, so confirm at checkout.
Do I need every supplier?
No. This is a directory, not a shopping list. How we combine them for each tier is covered in the guides, starting with the Tier 1 guide and the Best Practices Guide.
Do you have a catch-all email supplier?
Not yet. We haven't found one we're happy to recommend. When we do, it goes here and members hear about it first.
Can I suggest a supplier?
Yes. Tell us through the helpdesk. We test it on our own servers before it makes the page.
