Welcome back to the SEO Simplified series! This 6-part guide is designed to help you understand how SEO really works in 2025 and how to use it to grow your business online in a way that feels clear, doable, and not overwhelming.

If you’ve ever caught yourself wondering, “Is my website actually doing anything for my business?” – you’re not alone. The answer to that question starts with an SEO audit.

An SEO audit is a step-by-step evaluation of your website’s performance across the four essential elements of SEO: On-Page SEO, Off-Page SEO, Technical SEO, and Content.

Running your own DIY SEO audit will help you uncover technical issues, improve visibility, and attract more organic traffic—without the price tag of hiring an expert.

In today’s post, we’re diving into a complete SEO checklist you can follow to audit your own website and spot opportunities for improvement.

Let’s get to work!

Step 1: Set Clear Goals

Before diving into the details, clarify what you want from this audit. Do you want to:

• Boost your search visibility?
• Fix technical issues?
• Improve conversions or user experience?

Clear goals keep your audit focused and give you benchmarks for success.

👉 Example: If your site gets plenty of traffic but few inquiries, your goal might be to improve conversions (better CTAs, stronger content). If you have little to no organic traffic, your focus should be on keyword targeting and technical fixes.

Step 2: Technical SEO Audit

Search engines need to crawl and understand your site. Start with these basics:

• Mobile-friendliness: Test your site using Google’s Mobile-Friendly Test. Example: If text is too small or buttons are too close together, adjust your CSS or theme settings.

• Page speed: Run your site through PageSpeed Insights or GTmetrix. Example: If images are slowing you down, compress them with TinyPNG or re-export them in WebP format.

• Crawlability: In Google Search Console, go to Coverage. Example: If pages are marked “Excluded,” they may be blocked by robots.txt or missing from your sitemap.

• XML Sitemap: Check your sitemap at yourwebsite.com/sitemap.xml. Example: If it doesn’t include all important pages, regenerate it with your SEO plugin (like Yoast or RankMath).

• 404 errors: Use Broken Link Checker to find them. Example: If a blog post link is broken, set up a 301 redirect to a relevant page.

Step 3: Keyword Analysis

Your keywords are the bridge between your content and your audience. Audit them by asking:

• Are you targeting relevant keywords in your niche?
• Do they match search intent (what your customers are actually typing)?
• Are they realistic in terms of search volume and competition?

Update your keyword strategy as needed to align with your business goals.

• Check current keywords: Use Ubersuggest or SEMRush. Example: If you’re a therapist in Denver, but your site only ranks for “therapy tips,” you’ll need to target local intent keywords like “Denver trauma therapist.”

• Evaluate intent: Search your target keyword in Google and scan the results. Example: If “how to build a raised bed” brings up guides and tutorials, you shouldn’t target it with just a product page—you’d need a helpful blog post.

Step 4: On-Page SEO Checklist

• Meta titles & descriptions: Use Yoast SEO or RankMath to preview how your titles look in search results. Example: Change “Home | Smith Consulting” to “Small Business Consulting in Austin, TX | Smith Consulting.”

• Header tags: Scan your page in Chrome’s “View Page Source.” Example: If you see multiple <h1> tags, fix it so there’s only one main H1.

• Images: Right-click > Inspect to check if your image has alt text. Example: Instead of alt=”IMG_1234.jpg”, use alt=”Golden retriever senior dog rescue in Texas”.

• Internal links: Example: From your “Services” page, link to a related blog post for deeper reading.

Step 5: User Experience (UX)

Search engines pay attention to how users interact with your site. Audit for:

• Navigation: Ask a friend to find your “Contact” page in under 10 seconds. If they struggle, simplify your menu.

• CTAs: Example: Change vague “Learn More” buttons to “Schedule Your Free Consultation.”

• Layout: Use short paragraphs, bullet points, and headings. Example: Turn a 400-word wall of text into sections like “Why This Matters,” “How It Works,” and “Next Steps.”

Step 6: Content Audit

Content is still king, but only if it’s helpful and relevant. Review your site for:

• Find thin content: Use Screaming Frog (free version up to 500 URLs) to scan word counts. Example: A 150-word blog post may need expansion or consolidation.

• Update old posts: Example: If you wrote “Top SEO Tips for 2021,” refresh the title and content for 2025.

• Fill gaps: Use Google’s “People Also Ask” box. Example: If people also search “How often should I update my sitemap?”, add a section answering it.

Step 7: Backlink Profile Audit

Backlinks remain one of the top ranking factors. Audit yours by:

• Checking backlinks: Use Ahrefs Free Backlink Checker. Example: If most links come from low-quality directories, prioritize outreach for guest posts or partnerships instead.

• Fix unlinked mentions: Set up Google Alerts for your brand name. Example: If a blog mentions your business but doesn’t link, email them and ask to add the link.

Step 8: Local SEO (If Applicable)

If your business serves a specific location, local SEO matters. Check:

• Google Business Profile: Search your business name on Google. Example: If your listing has outdated hours, update them immediately.

• NAP consistency: Use Moz Local to check directories. Example: If Yelp lists “123 Main Street” but your website says “123 Main St.,” update it for consistency.

Step 9: Social Media & Off-Page Signals

While not direct ranking factors, social presence boosts authority.

• Profile check: Example: If your Instagram bio doesn’t link to your site, add it.

• Share content: Example: When publishing a blog post, create a Pinterest pin with keyword-rich descriptions to expand reach.

Step 10: Analytics & Reporting

Data drives smart decisions. Set up and track:

• Google Analytics: Example: Set up a goal for “Contact Form Submission” so you know how many inquiries come from organic search.

• Search Console: Example: If your site is showing “Crawled – currently not indexed,” request indexing or check for technical issues.

• Rank tracking: Use free tools like SERanking or paid ones like Ahrefs. Example: Track your top 10 target keywords monthly to measure progress.

Step 11: Security Audit

Last but not least, a secure site builds trust:

• Security scans: Detect vulnerabilities early by using tools like MalCare.

• SSL certificate: Example: If your site still loads as “http://” instead of “https://,” contact your host to install SSL.

• Updates: Example: If you use WordPress, keep plugins/themes updated weekly to avoid vulnerabilities.

Final Thoughts

By following this DIY SEO checklist, you’ll uncover what’s holding your site back and create a roadmap for improvement.
