Blog Post SEO Checklist: 24 Checks Before You Hit Publish
June 11, 2026 · 7 min read
An interactive on-page SEO checklist covering research, writing, technical setup, and post-publish follow-through. Your progress saves as you go.
Most blog posts don’t fail at writing; they fail at everything around the writing. The keyword was never validated, the title truncates, the post never got an internal link, nobody confirmed Google indexed it. Each miss is small. Together they’re the difference between a post that earns traffic for years and one that nobody ever sees.
This is the checklist we run content through before and after it ships, 24 checks across four phases. It’s interactive: tick items off as you work and your progress saves in this browser, so you can keep it open next to your draft.

A few notes from running this process across a lot of content:
- The “before you write” phase is where posts are won. A perfectly optimized post on a query nobody searches (or one your own site already targets) is wasted work. If you only adopt one phase, adopt that one, and if you want the research done for you, here’s the full topic-research system.
- Don’t keyword-stuff your way through the writing phase.The checks say “naturally” for a reason: subheadings and copy should read like they were written for the reader who searched, not for the crawler that followed.
- The after-publish phase is the one everyone skips.Indexing confirmation takes two minutes and catches silent failures (here’s why pages don’t get indexed). The 30-day review catches titles that rank but don’t get clicked. The scheduled refresh is what keeps the post earning after year one instead of decaying.

The Blog Writer bakes these checks into every draft: validated keywords, cited research, optimized title and meta, internal links, and valid Article schema, and Content Refresh handles the revisit cycle automatically.
On-page SEO, answered
What are the most important on-page SEO factors for a blog post?
Targeting one clear query with real demand, answering it directly and better than the current results, and making the page technically legible: keyword-aligned title and H1, descriptive subheadings, internal links, a compelling meta description, and valid structured data. Everything else compounds on those.
How long should a blog post be for SEO?
As long as the query deserves, and no longer. Length is not a ranking factor; coverage is. Check the posts that currently rank: if they’re 800-word answers, a 4,000-word essay isn’t an advantage, it’s a bounce. If they’re comprehensive guides, a thin post can’t compete.
Should I optimize the post before or after publishing?
Both, on different things. Keyword choice, structure, and metadata belong before publish (that’s most of this checklist). CTR tuning, internal links from new content, and refreshes are after-publish work, driven by your real Search Console data at 30 days and beyond.
How often should I revisit an old post?
Put every meaningful post on a 6 to 12 month review cycle. Rankings decay as information ages and competitors update; a scheduled refresh catches the slide early, when winning the position back is cheap.
