How to Improve Your SEO Score from 70 to 90 Without a Developer

“Why is my score stuck at 72?” a founder asked me recently. They had built a polished website with a no-code platform, published useful content, and expected the audit to show a clean result.

The missing points were not hidden in complex code. The site had a weak title tag, no schema markup, oversized images, duplicate URL versions, and a robots.txt file that needed attention.

That pattern is common with AI-built and no-code websites. A score in the 70s usually means the foundation works, but several cheap fixes remain.

You can often move from 70 to 90 in about an hour without hiring a developer.

What changes between a 70 score and a 90 score?

Area	A 70 score usually looks like	A 90 score usually looks like
Page title	Missing, duplicated, or too vague	One clear, unique title for every important page
Meta description	Missing or truncated	Unique description with a clear benefit and search intent
Schema markup	No structured data	Relevant JSON-LD for the page type
Headings	Multiple H1s or skipped heading levels	One descriptive H1 followed by logical H2 and H3 sections
Images	Large files with names like IMG_4821.jpg	Compressed files with descriptive names and useful alt text
Internal links	Important pages are isolated	Key pages are connected with descriptive anchor text
Crawl files	Robots.txt is missing or blocks useful pages	Robots.txt is accessible and correctly configured
AI search readiness	Content is difficult to extract or interpret	Clear answers, structured sections, and an llms.txt file
URL structure	HTTP, HTTPS, www, and trailing-slash duplicates	One preferred URL version with consistent redirects
Security	Exposed files, leaked keys, or weak protections	HTTPS and basic vulnerability checks completed

A score is not a ranking guarantee. It is a practical diagnostic. Traditional SEO, answer engine optimization, and website security are three connected pillars of a healthy site.

The one-hour SEO score improvement playbook

1. Rewrite the page title and meta description

Start with your homepage and your three most important pages.

Use the free Meta Tag Generator. It includes a live Google preview, so you can see how the title and description may appear in search results.

Write a title that:

• Describes the page accurately
• Includes the main topic or service
• Gives the most important words early
• Stays unique across your website

Write a meta description that:

• Explains the benefit of visiting the page
• Matches the page content
• Uses natural language
• Gives the reader a reason to click

Do not stuff keywords into either field. A clear title helps Google understand the page, while a clear description helps people choose it.

2. Add the right Schema Markup

Schema markup gives search engines and answer engines more context about your page.

Choose the type that matches the content. Do not add every schema type just because it is available.

Useful options include:

• Organization schema for a company or brand
• LocalBusiness schema for a local service
• Article schema for a blog post
• FAQPage schema for a genuine FAQ section
• BreadcrumbList schema for site navigation
• Product schema for a product page

Use the free Schema Markup Generator. Pick a type, complete the fields, generate the JSON-LD, and paste it into your site using your platform’s custom code or SEO settings.

Keep the markup truthful. Your schema should describe visible page content. Do not mark up reviews, prices, FAQs, or products that visitors cannot see.

Structured data supports both traditional SEO and answer engine optimization. It helps systems identify what a page is, who created it, and how its information fits together.

3. Publish proper robots.txt and llms.txt files

Your website needs to tell crawlers what they can access.

Use the free Robots.txt Generator to create a file for your site root. Check that it does not block important pages, images, stylesheets, or scripts.

A basic mistake looks like this:

❌ Blocking the entire site with Disallow: /

✅ Blocking private areas while allowing public pages to be crawled

Also check that your XML sitemap is available and contains your preferred, indexable URLs.

For answer engine optimization, create an llms.txt file. This gives AI search systems a clearer summary of your site and its most useful content.

Treat llms.txt as a supporting file, not a replacement for strong SEO. Your pages still need clear writing, crawlable links, useful headings, and credible information.

Both generators are free. No login, email, or paywall is required.

4. Fix heading order and use one H1 per page

Open each important page and inspect the visible headings.

Use this structure:

H1: How to Improve Your Website SEO

H2: Fix Your Page Title
H2: Add Schema Markup
H2: Improve Internal Links
  H3: Link from High-Traffic Pages
  H3: Use Descriptive Anchor Text

Use one H1 that describes the page. Use H2 headings for major sections and H3 headings for supporting points.

❌ Using the logo, site name, and page title as three H1 headings

✅ Using one clear H1 followed by organized sections

This helps readers scan the page and helps answer engines extract direct responses. Put the answer near the start of each section when possible. A short, self-contained explanation is easier to understand than a long introduction.

5. Compress, rename, and describe your images

Large images can slow down a no-code or AI-built website quickly.

Before uploading an image:

1. Compress it with your normal image editor or platform tool.
2. Convert it to WebP when your platform supports it.
3. Rename it descriptively.
4. Add real alt text.
5. Confirm the image has width and height settings.

❌ IMG_4821.png with alt text that says image

✅ small-business-seo-audit-results.webp with alt text that says Founder reviewing a website SEO score on a laptop

Write alt text for a person using a screen reader, not for a keyword scanner. Include a keyword only when it accurately describes the image.

6. Repair thin pages and add internal links

A page can be technically valid but still underperform because it has little useful content or no path to the rest of your website.

Look for:

• Pages with very little original information
• Important pages with no internal links
• Blog posts that never link to a service page
• Orphaned pages that are not connected from navigation or content
• Links using vague text such as “click here”

Add links with descriptive anchor text.

❌ Read more

✅ Read the complete AEO implementation guide

Link from your homepage, strongest blog posts, and relevant category pages to your key pages. Keep important pages within a few clicks of the homepage.

If your site already receives impressions, use the Search Console Regex Library to find useful queries. Filter for:

• Question queries
• Commercial and comparison searches
• Transactional terms
• Long-tail questions
• Non-branded searches

Find queries that already convert or attract impressions but do not have a dedicated page. Then create or improve a page that answers that exact need.

7. Kill duplicate URL versions

Your website should have one preferred version of each page.

Check whether these versions all resolve consistently:

• http://example.com
• https://example.com
• https://www.example.com
• https://example.com/
• https://example.com/index.html

Choose one canonical version, usually HTTPS, and redirect the others to it through your hosting or website platform.

Also check for duplicate page paths created by no-code templates, preview URLs, tracking parameters, or old slugs.

❌ Several URL versions showing similar content

✅ One preferred URL with consistent redirects and canonical signals

Duplicate URL versions can split ranking signals and confuse crawlers. They can also make your audit report look worse than the visible website suggests.

8. Run a vulnerability check before you re-scan

Do not spend an hour polishing meta descriptions while your website exposes a backup file or API key.

Fast website builders help you launch quickly, but speed can leave behind:

• Public environment files
• Exposed configuration files
• Leaked passwords or API keys
• Outdated software
• Missing security headers
• Unsafe login forms
• Cookie and HTTPS issues

Run the free Vulnerability Check before your final SEO scan. It checks security weaknesses separately from the visible SEO score and provides a practical report.

Website security belongs in the same launch checklist as SEO and AEO. A perfect title tag cannot compensate for an exposed secret or a compromised form.

9. Re-check the site and fix the remaining high-impact issues

Run the free SEO/AEO analyzer again after making your changes.

The analyzer checks areas such as:

• HTTPS and SSL
• Mobile configuration
• Title tags and meta descriptions
• H1 structure
• Image alt text
• Internal and external links
• Schema markup
• Robots.txt
• XML sitemap
• Open Graph tags
• Security headers
• Content depth
• AEO signals

It also provides a category breakdown and prioritized action plan. Use the second report to confirm that each fix worked.

The full report is free every time. There is no login, no email requirement, and no paywall hiding the important recommendations.

What not to chase first

When your score is 70, avoid spending the first hour on low-impact changes.

❌ Rewriting every paragraph before fixing a missing title tag

❌ Adding five schema types that do not match the page

❌ Chasing a perfect score from one audit tool

❌ Blocking crawlers because you are unsure what robots.txt does

❌ Ignoring security because the site looks professional

✅ Fix missing metadata, crawl access, headings, images, links, duplicate URLs, and vulnerabilities first

These are common SEO ranking factors across small business websites, no-code projects, and AI-built sites.

The practical next step

Run a full website SEO audit, apply the quick wins, complete the Vulnerability Check, and scan again. Then review your Search Console queries for pages you should create next.

The free Smart Analytics audit combines traditional SEO checks with answer engine optimization and AI search optimization signals. It is available without signup, email, or a paywall, and you keep the complete report.

Use it to check whether your site is ready for Google, ChatGPT SEO ranking opportunities, Perplexity SEO optimization, and the wider shift toward digital marketing analytics.
