Run a Complete SEO Audit for Your Website

The Walkthrough
Step 1: Set Up Semrush and Add Your Website
What to do: Go to Semrush and create an account. There’s a free trial available. Once in, go to Site Audit under the “On Page & Tech SEO” section. Add your website URL and run a full crawl.
Why you’re doing it: A site audit crawls every page on your website and checks for technical SEO issues — broken links, slow pages, missing meta descriptions, duplicate content, and hundreds of other problems that prevent Google from ranking you.
What to expect: Setup takes 5 minutes. The crawl takes 10–30 minutes depending on site size. You’ll get a health score out of 100 and a prioritized list of issues.
Common mistakes: Don’t panic at a low score. Most small business sites score 50–70 on their first audit. The point is to know what to fix, not to feel bad about it.
Step 2: Fix Critical Technical Issues First
What to do: In the Site Audit results, sort by “Errors” (the most critical issues). Common ones include: broken internal links, pages with no meta description, missing alt text on images, slow-loading pages, and pages blocked from indexing. Fix the errors first, then warnings, then notices.
Why you’re doing it: Google can’t rank what it can’t crawl. Technical errors literally prevent search engines from seeing your pages. Fixing these is the fastest way to improve rankings because you’re removing roadblocks.
What to expect: Most technical fixes are straightforward — updating links, adding meta descriptions, compressing images. Budget 1–2 hours to knock out the critical errors.
Common mistakes: Don’t try to fix everything at once. Focus on errors that affect your most important pages (homepage, service pages, contact page) first.
Step 3: Research Your Target Keywords
What to do: Go to Semrush’s Keyword Magic Tool. Type in what your customers would search for to find your business (e.g., “plumber Houston,” “wedding photographer prices,” “best CRM for small business”). The tool shows you search volume, keyword difficulty, and related keywords.
Why you’re doing it: You need to know what words people actually type into Google so you can use those words on your website. Guessing at keywords is the #1 reason small business SEO fails.
What to expect: You’ll discover keywords you never thought of. Look for keywords with decent search volume (100+/month) and keyword difficulty under 40 — these are realistic targets for a small business site.
Common mistakes: Don’t target the most competitive keywords. “Plumber” has millions of searches but you’ll never rank for it. “Emergency plumber Galveston TX” has fewer searches but you can actually win that one.
Step 4: Spy on Your Competitors
What to do: In Semrush’s Competitive Research section, enter your top 3 competitors’ websites. Look at which keywords they rank for, which pages drive their most traffic, and where their backlinks come from.
Why you’re doing it: Your competitors have already done the keyword research for you — they just don’t know it. If they’re ranking for a keyword, that keyword has been validated. You just need to create better content targeting the same terms.
What to expect: 30 minutes of analysis per competitor. You’ll find keyword gaps — terms your competitors rank for that you don’t. These are your biggest opportunities.
Step 5: Build Your Action Plan With AI
What to do: Export your top 20 keyword opportunities and your site audit findings. Paste them into Claude or ChatGPT with this prompt: “Here are my SEO audit results and target keywords. Create a 30-day SEO action plan. Week 1 should focus on technical fixes. Weeks 2–3 on optimizing existing pages for target keywords. Week 4 on creating new content for keyword gaps. Prioritize by impact.”
Why you’re doing it: An audit without a plan is just a list of problems. The AI turns your data into a structured roadmap you can actually follow.
What to expect: A clear 30-day plan with specific tasks for each week. Follow it consistently and you should see ranking improvements within 60–90 days.
Confidence Level
This workflow is Beta — Based on Best Available Knowledge. Semrush is the industry-standard SEO platform used by agencies and in-house teams worldwide. Features and pricing verified as of February 2026. SEO improvements typically take 60–90 days to show results — this is a long-term investment, not an overnight fix.
What to Do If It Doesn’t Work
Site audit won’t run: Make sure your site isn’t blocking crawlers. Check your robots.txt file.
Can’t find good keywords: Broaden your search terms or try longer phrases. Add your city or niche to find less competitive long-tail keywords.
Competitors seem impossible to beat: Focus on local and long-tail keywords first. You don’t need to outrank Amazon — you need to outrank the other three businesses in your area doing the same thing.
Rankings not improving after 30 days: SEO takes time. Keep publishing optimized content and building the technical foundation. Most sites see meaningful movement at 60–90 days.
