How to Fix SEO Issues Without a Developer

You ran an audit. You found problems. Now what? If you are a marketer, content creator, or small business owner without a developer on staff, the list of issues can feel overwhelming. The good news: most common SEO and GEO issues can be fixed without writing a single line of code.

This guide covers the practical tools and techniques you can use to fix the most frequent audit findings yourself.

First: Know What You Are Fixing

Before you start fixing anything, you need a clear picture of what is broken. Run an automated audit to get a prioritized list of issues. SiteCrawlIQ's AI analysis categorizes findings into "Fix Now" (critical), "Fix Next" (important), and "Fix Later" (nice-to-have), so you know where to focus.

The most common issues found in website audits fall into categories that are largely fixable without developer help:

Missing or duplicate meta tags (found on 67% of sites)

Missing image alt text (73% of sites)

No llms.txt file (89% of sites)

Incomplete schema markup

Poor heading structure

Redirect issues

Missing sitemap entries

Fixing Meta Tags (Title and Description)

WordPress

Install Yoast SEO or Rank Math (both free). These plugins add a meta box below each page/post editor where you can set custom title tags and meta descriptions. Yoast also shows a live preview of how your page will appear in search results.

Shopify

Edit meta tags directly in the admin: go to the page or product, scroll to the bottom, and click "Edit website SEO." You can set the page title and meta description without touching any code.

Squarespace

Navigate to the page, click the gear icon, and open the SEO tab. Enter your custom title and description.

Wix

Open the page in the editor, click "Page SEO" in the settings panel, and fill in the title tag and meta description fields.

General Rule

Every modern CMS has a built-in or plugin-based way to set meta tags. If yours does not, it is time to switch CMS platforms.

Adding Image Alt Text

Missing alt text is the single most common accessibility and SEO issue. Fixing it is straightforward:

Open your CMS media library

Click on each image

Add a descriptive alt text that explains what the image shows

Keep it under 125 characters

Include relevant keywords naturally - do not keyword-stuff

Tips for good alt text:

Describe what the image actually shows: "Bar chart showing 47% growth in AI search queries from 2024 to 2026"

Skip "image of" or "picture of" - screen readers already announce it as an image

For decorative images (backgrounds, spacers), use an empty alt attribute

For large sites, batch-update alt text using your CMS's media manager or a plugin like Auto Image Alt Text for WordPress.

Creating an llms.txt File

This is one of the highest-impact, lowest-effort GEO fixes. An llms.txt file is a plain text file at your site root that describes your business for AI engines.

Most CMS platforms let you upload files to the root directory:

WordPress: Upload via FTP/SFTP to the root folder, or use a plugin like "Add Custom File" to place it at yoursite.com/llms.txt

Squarespace/Wix: Use the custom code injection or file hosting feature, or host the file on a CDN and redirect to it

Static sites: Simply add the file to your public directory

For details on what to include, see our [llms.txt guide](/blog/how-to-check-llms-txt).

Adding Schema Markup Without Code

Plugin-Based Approach (Recommended)

WordPress: Yoast SEO (free) adds basic schema automatically. Schema Pro ($79/year) adds advanced types. Rank Math includes comprehensive schema in its free version.

Shopify: JSON-LD for SEO app (free) adds Product, Breadcrumb, and Organization schema automatically.

Squarespace: Basic schema is built in. For advanced types, use the code injection header to add JSON-LD.

Generator Tools

If your CMS does not support schema plugins, use a generator:

Go to Google's Structured Data Markup Helper or Schema.org

Select your schema type (Organization, FAQPage, Article, etc.)

Fill in the fields

Copy the generated JSON-LD code

Paste it into your CMS's header code injection area

This takes 5-10 minutes per schema type and does not require coding knowledge.

Fixing Heading Structure

Poor heading hierarchy (missing H1, multiple H1s, skipped heading levels) is common and easy to fix:

Every page should have exactly one H1 tag - this is usually the page title

Use H2 for major sections

Use H3 for subsections within H2 sections

Never skip levels (do not go from H2 to H4)

In most CMS editors, headings are set via a dropdown menu in the content editor. Select the text and change it to the correct heading level.

Managing Redirects

Broken links and redirect chains hurt user experience and waste crawl budget. Fix them without a developer:

WordPress: Use the Redirection plugin (free) to create 301 redirects and identify 404 errors

Shopify: Manage redirects in Settings > Navigation > URL Redirects

Squarespace: Settings > Advanced > URL Mappings

Cloudflare: Use Page Rules for redirects (works with any CMS)

Key rules:

Always use 301 (permanent) redirects, not 302 (temporary), for changed URLs

Avoid redirect chains - point the old URL directly to the final destination

Fix internal links to point to the current URL rather than relying on redirects

Compressing Images

Large images are the most common cause of slow LCP scores. Fix this without developer tools:

TinyPNG/TinyJPG (free online tool) - Compress images before uploading. Reduces file size by 50-80% with no visible quality loss.

ShortPixel (WordPress plugin) - Automatically compresses images on upload and can bulk-optimize existing images.

Squoosh (free Google tool) - Convert images to WebP/AVIF format for additional size reduction.

Target: hero images under 200KB, content images under 100KB.

Editing robots.txt

Your robots.txt controls which crawlers can access your site. To allow AI crawlers:

WordPress: Use Yoast SEO's robots.txt editor (SEO > Tools > File Editor) or edit the file via FTP

Shopify: Edit via Online Store > Themes > Edit Code > robots.txt.liquid

Squarespace: Limited control; contact support for custom directives

Static sites: Edit the file directly in your public directory

Add these lines to allow AI crawlers:

```
User-agent: GPTBot
Allow: /

User-agent: ClaudeBot
Allow: /

User-agent: PerplexityBot
Allow: /
```

For full details, see our [AI crawler robots.txt guide](/blog/ai-crawler-robots-txt-guide).

The Most Important Step: Finding the Issues First

All of these fixes are straightforward once you know what needs fixing. The audit is the critical first step. Without it, you are guessing - and guessing means either fixing the wrong things or missing high-impact issues entirely.

SiteCrawlIQ's free tier lets you crawl up to 200 pages and get AI-powered recommendations that tell you exactly what to fix and in what order. No developer required to run the audit or to fix most of the issues it finds.

Key Takeaways

Most common SEO and GEO issues can be fixed through CMS settings, plugins, and free online tools

Meta tags, alt text, and heading structure are fixable in any modern CMS editor

Schema markup can be added via plugins (Yoast, Rank Math) or code generators without coding

Image compression is the fastest way to improve page speed

Creating an llms.txt file takes 10 minutes and significantly boosts GEO readiness

The audit itself is the most important step - you cannot fix what you have not identified

Frequently Asked Questions

Do I really need a developer for any SEO fixes?

For most sites, no. The exceptions are custom JavaScript rendering issues, server-side redirect configurations, advanced Core Web Vitals optimization (code splitting, lazy loading), and custom schema implementations that go beyond what plugins support. Everything else - meta tags, images, content, basic schema, robots.txt - is doable without a developer.

Which CMS is best for SEO without technical expertise?

WordPress with Yoast SEO or Rank Math gives you the most control over SEO elements without coding. Shopify is excellent for e-commerce SEO. Squarespace and Wix have improved significantly but offer less flexibility for advanced optimizations.

How do I know if my fixes are working?

Re-run your audit after making changes. SiteCrawlIQ stores historical crawl data, so you can compare your before and after scores. Also monitor Google Search Console for crawl error changes and impression/click trends over the following 2-4 weeks.
