The Free SEO Stack

SEO suites like Ahrefs, SEMrush, and Moz cost $99-$500/month. They are great if you do SEO professionally and need keyword research, rank tracking, backlink analysis, and competitive intelligence. If you are a solo founder, indie developer, or small business owner who just needs to ship optimized pages, you can do the technical SEO work with four free browser tools and skip the subscription entirely.

What Technical SEO Actually Needs

For 90% of sites, the on-page technical SEO work is:

1. Write a good title and meta description for every page
2. Preview the snippet to catch truncation
3. Add structured data (schema) for FAQ, Article, Product, etc.
4. Configure robots.txt to control crawling
5. Submit a sitemap to Google Search Console

That is the work. The four tools below cover steps 1-4. Search Console handles step 5 for free.

Tool 1: SERP Preview

free SERP preview tool — paste your title, meta description, and URL. See exactly how the snippet will appear in Google. Toggle desktop and mobile. Catch truncation before publishing. Includes SEO score and "copy meta tags as HTML" so you can paste directly into your page head.

Tool 2: Meta Tag Generator

meta tag generator — generates the full set of meta tags for any page: title, description, Open Graph (for social sharing), Twitter Cards, canonical URL, viewport, and more. Copy-paste into your page head. Pairs naturally with the SERP preview.

Tool 3: Schema Markup Generator

schema markup generator — generates JSON-LD structured data for FAQ, Article, Product, Recipe, Event, LocalBusiness, and more. Drop the JSON-LD into a script tag in your page. Improves rich snippet eligibility (FAQ accordions, ratings, prices, etc.) which increases CTR.

Tool 4: Robots.txt Generator

robots.txt generator — builds a valid robots.txt with presets for common scenarios: allow all, block staging, allow crawlers but block AI training scrapers, etc. Copy the output to your site root. Done.

The Full Workflow for a New Page

1. Draft the page content
2. Use the meta tag generator to draft title, description, and OG tags
3. Preview in the SERP preview tool, adjust until both desktop and mobile look good
4. Add FAQ schema if applicable (use the schema generator)
5. Verify your robots.txt allows the page (use the robots.txt generator)
6. Publish and submit to Google Search Console for indexing

Total time: 10-15 minutes per page. Total cost: $0/month.

When to Upgrade to a Paid Suite

Move to a paid SEO suite when you need: bulk keyword research at scale, automated rank tracking across hundreds of keywords, competitive backlink analysis, content gap analysis, or site-wide technical audits with hundreds of pages. The free stack does not replace these. It replaces the everyday "ship a new page" workflow that the suites also bundle but charge $99/month for.
