The Complete Custom Website Checklist: Blogs & Content Sites (SEO + Security)

Custom-built blogs and content sites skip the guardrails a mainstream CMS or theme would normally provide, which means the things most likely to get missed are exactly the technical and security basics that come "free" elsewhere. This checklist covers what a genuinely thorough launch and maintenance process should include, organized so nothing quietly falls through the cracks.

Pre-Launch Technical Foundations

[ ] Robots.txt exists, is correctly formatted, and isn't accidentally blocking the whole site (a common leftover from staging)
[ ] XML sitemap is generated, accurate, and submitted to Search Console
[ ] Canonical tags are present and correct on every page, including paginated and filtered views
[ ] URL structure is clean, descriptive, and uses hyphens rather than underscores
[ ] HTTPS is enforced site-wide with a valid certificate and no mixed-content warnings
[ ] All HTTP URLs redirect to HTTPS with a single 301, not a chain
[ ] 404 errors return a genuine 404 status code, not a 200 on a "not found" page
[ ] A custom, helpful 404 page is in place, distinct from a generic server error page
[ ] Staging or development subdomains are noindexed and not accidentally linked from the live site

> Tool tip: Run a full pass with the SEO Audit tool before launch to catch foundational technical issues while they're still cheap to fix.

On-Page SEO Essentials

[ ] Every page and post has a unique, descriptive title tag within a safe display length
[ ] Every page and post has a unique meta description
[ ] Exactly one H1 per page, matching the actual topic
[ ] Header structure (H2, H3) follows a logical outline, not just visual styling
[ ] Primary keyword appears naturally in the title, first paragraph, and at least one subheading
[ ] No duplicate or near-duplicate content across posts, tags, or category archives
[ ] Open Graph and Twitter Card meta tags are implemented for accurate social sharing previews

> Tool tip: Check your titles and descriptions with the Meta Tags Analyzer and verify keyword usage isn't over- or under-optimized with the Keyword Density Checker.

Content Structure & E-E-A-T Signals

[ ] Every post has a clear, credentialed author byline linked to a real author bio page
[ ] Author pages include genuine credentials or experience relevant to the content's subject matter
[ ] Publish and last-updated dates are visible and accurate
[ ] A clear editorial or fact-checking process is documented somewhere on the site, even briefly
[ ] Sources and claims are cited where genuinely relevant, especially for factual or data-driven content
[ ] Older, high-potential posts have a defined refresh schedule rather than being published once and forgotten

Site Architecture & Internal Linking

[ ] Category and tag pages are genuinely useful, not just thin auto-generated archives
[ ] Category/tag overlap doesn't create excessive duplicate or near-duplicate archive pages
[ ] Pagination on archive and category pages uses proper rel="next"/"prev" patterns or is otherwise handled cleanly
[ ] Every published post is reachable within a reasonable number of clicks from the homepage
[ ] No orphaned posts with zero internal links pointing to them
[ ] Related-posts modules link to genuinely relevant content, not random or purely recent posts
[ ] Internal links use descriptive anchor text, not "click here" or bare URLs

> Tool tip: Use the Broken Links Finder periodically, since content sites accumulate dead internal and outbound links faster than most owners expect.

Images & Media

[ ] Every image has accurate, descriptive alt text
[ ] Images are compressed and served at appropriately sized dimensions, not full-resolution originals
[ ] Descriptive, keyword-relevant file names are used instead of generic camera-generated names
[ ] Lazy loading is applied to below-the-fold images without breaking layout or triggering shift
[ ] Embedded video includes captions or a transcript where relevant

> Tool tip: Check the Page Size Checker on your heaviest posts to see how much weight images are contributing before optimizing.

Security Essentials

[ ] CMS, plugins, themes, and any custom code dependencies are kept current with security patches
[ ] Admin login is protected with strong, unique credentials and two-factor authentication
[ ] Login attempts are rate-limited to prevent brute-force attacks
[ ] The admin login URL isn't the obvious default if the platform allows customization
[ ] Automated, tested backups run on a regular schedule and are stored off-server
[ ] File and directory permissions follow least-privilege principles, not broad open access
[ ] Security headers are configured: Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Strict-Transport-Security
[ ] Unused plugins, themes, or scripts are removed entirely, not just deactivated
[ ] Database credentials and API keys are stored outside the web root, never in publicly accessible files

> Tool tip: Run a Google Malware Checker and Blacklist Lookup scan periodically to catch a compromise early, before it does lasting reputational damage.

Spam & Abuse Protection

[ ] Comment forms use spam filtering or a CAPTCHA-equivalent, not left completely open
[ ] Contact and newsletter signup forms are protected against automated bot submissions
[ ] Comment moderation is genuinely enforced, not just technically available
[ ] Outbound links in user-generated comments use rel="nofollow" or rel="ugc" by default

Privacy, Legal & Compliance

[ ] A privacy policy is published and accurately reflects actual data collection practices
[ ] Cookie consent is implemented where legally required for your audience's location
[ ] Any email capture form clearly discloses what subscribers are signing up for
[ ] Third-party embeds (ads, analytics, social widgets) are accounted for in your privacy disclosures
[ ] Basic accessibility standards are met: sufficient color contrast, keyboard navigability, proper alt text

Performance & Core Web Vitals

[ ] Page load speed is tested on both mobile and desktop, not just desktop
[ ] Core Web Vitals are within acceptable thresholds across your main templates
[ ] Font loading is optimized to avoid invisible text or major layout shift
[ ] Third-party scripts (ads, embeds, widgets) are audited for their actual performance cost

> Tool tip: Check both the Page Speed Checker and Pagespeed Insights Checker across your template types, since a single homepage check often misses issues specific to your post or category templates.

Analytics & Tracking

[ ] Analytics tracking is installed and verified as firing correctly, not just installed
[ ] Search Console is verified and a sitemap is submitted
[ ] Key events (newsletter signups, affiliate clicks, ad interactions) are tracked as defined conversions
[ ] Internal site search, if present, is tracked to reveal content demand and gaps

Post-Launch Monitoring & Maintenance

[ ] A recurring schedule exists for checking Search Console for new indexing or manual action issues
[ ] Broken link checks are run on a regular cadence, not just once at launch
[ ] Old, underperforming posts are periodically reviewed for refresh, consolidation, or removal
[ ] Uptime is monitored so downtime is caught immediately, not discovered days later

Next step: Once you've worked through this checklist, run the SEO Audit tool one more time as a final pass — it's the fastest way to confirm everything above is actually holding together in practice, not just checked off on paper.
