90-Day Audit: Improve Marketing with AI & A/B Tests

As a marketing professional, I’ve seen countless businesses struggle to truly improve their outreach and impact, often because they’re chasing the next shiny object instead of refining what they already have. This guide isn’t about revolutionary new tactics; it’s about systematically enhancing your existing marketing efforts. Ready to stop guessing and start growing?

1. Conduct a Rigorous 90-Day Marketing Audit

Before you can fix something, you need to understand exactly what’s broken. My first step with any new client is always a deep, no-holds-barred audit. We’re talking about a comprehensive review of everything, not just surface-level metrics. You need to analyze your entire marketing ecosystem from the last 90 days. This isn’t a quick glance; it’s a forensic investigation.

Actionable Step: Create a spreadsheet with columns for ‘Channel/Asset’, ‘Objective’, ‘Key Performance Indicator (KPI)’, ‘Actual Performance (Last 90 Days)’, ‘Target Performance’, ‘Variance’, and ‘Hypothesized Reason for Variance’.

Screenshot Description: Imagine a Google Sheet. Column A lists channels like “Paid Search (Google Ads)”, “Organic Search (Blog)”, “Email Marketing (Newsletter)”, “Social Media (LinkedIn)”, “Landing Page X”, “Webinar Series Y”. Column B has “Lead Generation”, “Brand Awareness”, “Customer Retention”. Column C has “CPL”, “Organic Traffic %”, “Open Rate”, “Engagement Rate”, “Conversion Rate”, “Attendee-to-MQL Rate”.

Pro Tip: Don’t just look at the numbers. Dig into the ‘why’. For instance, if your LinkedIn engagement is low, is it because your content isn’t relevant, or are you posting at the wrong times? I once had a client, a B2B SaaS company based out of the Atlanta Tech Village, who was convinced their social media wasn’t working. After this audit, we realized their best-performing posts were actually on Tuesdays and Thursdays at 10 AM EST, but they were posting most frequently on Mondays and Fridays. A simple timing adjustment made a significant difference.

Common Mistake: Focusing solely on vanity metrics like follower count instead of business-driving KPIs such as qualified leads, sales conversions, or customer lifetime value. Follower count doesn’t pay the bills; actual conversions do.

2. Optimize Your Highest-Traffic Landing Pages with A/B Testing

Your landing pages are often the last stop before conversion. If they’re not performing, all your upstream marketing efforts are wasted. I’m a firm believer that you should always start optimization where you have the most traffic, as that’s where even small improvements yield significant results quickly.

Actionable Step: Identify your top 3-5 landing pages by traffic volume using Google Analytics 4. For each page, set up an A/B test focusing on one critical element. I prefer Optimizely for its robust features, but VWO is another excellent choice. If you’re on a budget, many CRM platforms like HubSpot have built-in A/B testing for landing pages.

Specific Settings Example (Optimizely):

1. Navigate to ‘Experiments’ -> ‘New Experiment’ -> ‘A/B Test’.
2. Select ‘Web Page’ as the experiment type.
3. Enter the URL of your target landing page.
4. In the visual editor, create a variation. Start with a single element: change the headline (e.g., from “Sign Up Now” to “Get Your Free Demo Today”) or the primary call-to-action (CTA) button text/color.
5. Allocate traffic 50/50 to start.
6. Set your primary goal to ‘Clicks on CTA Button’ or ‘Form Submissions’.
7. Run the test for at least 30 days, or until statistical significance (usually 95% confidence) is reached. Don’t stop early just because one variant seems to be winning; that’s how you get misleading data.

Screenshot Description: An Optimizely interface showing two versions of a landing page side-by-side. One has a blue CTA button with “Download Now”, the other has a green button with “Get Your Report”. A small pop-up displays the traffic allocation and confidence level settings.

Pro Tip: Don’t try to test too many elements at once. You won’t know what caused the change. My rule of thumb: one variable per test. If you change the headline, the body copy, and the image, you’ve learned nothing about which specific change moved the needle.

Common Mistake: Running tests for too short a period or with insufficient traffic, leading to invalid results. A test needs to run long enough to account for weekly cycles and gather enough conversions to be statistically significant. A test with 10 conversions might show a 200% uplift, but it’s probably just noise.

3. Repurpose and Reinvigorate Your Top-Performing Content

You’ve already put in the hard work creating great content. Why let it gather digital dust? Smart marketers know how to squeeze every last drop of value from their existing assets. This isn’t about being lazy; it’s about being efficient and reaching new audiences on different platforms.

Actionable Step: Use your audit data (from Step 1) to identify your top 5-10 blog posts, whitepapers, or videos that have generated the most organic traffic, leads, or engagement in the last year. Then, brainstorm at least three new formats for each piece.

• Blog post -> Podcast episode: Turn a detailed “How-To” guide into an interview with an expert (you!) or a narrative discussion.
• Whitepaper -> Infographic & LinkedIn Carousel: Condense key data points and visuals into an eye-catching infographic. Break that infographic into a multi-slide carousel for LinkedIn.
• Webinar -> Short-form video clips & blog series: Extract 1-2 minute “aha!” moments from your webinar for YouTube Shorts or TikTok. Transcribe the webinar and create a 3-part blog series.
• Case Study -> Customer testimonial video & email sequence: Interview the featured client for a video, then build an email drip campaign around the success story.

Pro Tip: When repurposing, always consider the native platform. What works on a blog won’t directly translate to TikTok. You need to adapt the content, not just copy-paste it. For example, a detailed technical explanation from a whitepaper needs to be broken down into bite-sized, visually driven points for a social media carousel.

Common Mistake: Simply reposting old content without any adaptation. That’s not repurposing; that’s recycling, and it rarely performs well. Each platform has its own language, audience expectations, and format preferences.

4. Implement AI-Powered Content Enhancement Tools

The year is 2026. If you’re not using AI to assist your content creation and optimization, you’re falling behind. These tools aren’t here to replace human creativity, but to augment it, making you faster and more effective. I’ve found that integrating AI can shave off up to 20% of the time I spend on initial drafts and research.

Actionable Step: Integrate specific AI tools into your workflow. For content ideation and drafting, I rely heavily on Semrush’s AI Writing Assistant or Copy.ai. For SEO-focused content optimization, Surfer SEO with its AI capabilities is indispensable.

Specific Settings Example (Semrush AI Writing Assistant):

1. Navigate to ‘Content Marketing’ -> ‘Content Marketing Toolkit’ -> ‘SEO Writing Assistant’.
2. Enter your target keyword (e.g., “beginner’s guide marketing improvement”).
3. Select your target audience and tone of voice (e.g., ‘Professional’, ‘Informative’).
4. The tool will analyze top-ranking articles and provide recommendations for readability, SEO, originality, and tone.
5. Use the ‘Rephrase’ or ‘Expand’ functions within the editor to quickly generate alternative sentences or flesh out ideas. Pay close attention to the ‘Keyword Recommendations’ to ensure you’re naturally including relevant terms.

Screenshot Description: A split screen of Semrush’s SEO Writing Assistant. On the left, a text editor with a partially written article. On the right, a sidebar shows scores for Readability, SEO, Originality, and Tone, along with suggestions for improving each, including a list of recommended keywords to integrate.

Pro Tip: Always edit and fact-check AI-generated content. These tools are fantastic for getting past writer’s block and generating initial drafts, but they can occasionally produce factual errors or sound generic. Your human touch is what makes the content truly resonate.

Common Mistake: Over-reliance on AI to the point where your brand voice is lost. AI should be a co-pilot, not the pilot. I recently saw a company’s blog posts become so generic after they went “all in” on AI writing that their organic traffic actually dipped because the content lacked a unique perspective. Authenticity matters more than ever.

5. Establish a Feedback Loop with Your Sales Team

This might sound obvious, but you’d be surprised how often marketing and sales operate in silos. Your sales team is on the front lines; they hear directly from potential customers about their pain points, objections, and what truly resonates. This intelligence is gold for your marketing efforts.

Actionable Step: Schedule a mandatory, bi-weekly 30-minute sync meeting with your sales leadership. Use a shared Salesforce or HubSpot dashboard to review lead quality and conversion rates together. The marketing team should come prepared with questions like:

• “What were the top 3 objections you heard this week from marketing-qualified leads (MQLs)?”
• “Which pieces of content did prospects mention as most helpful in their decision-making process?”
• “Are we generating leads that fit our Ideal Customer Profile (ICP) as defined last quarter?”

Pro Tip: Don’t just ask for feedback; show them how you’re acting on it. If they tell you prospects are confused about a specific feature, go back, update your website’s feature page, and then report back to sales that you’ve addressed their concern. This builds trust and encourages more valuable feedback.

Common Mistake: Treating sales feedback as a complaint session rather than a strategic input. It’s not about blame; it’s about collective improvement. We once had a major disconnect where marketing was driving leads based on one product feature, but sales was finding those prospects were actually interested in a completely different, complementary product. A quick adjustment to our ad copy and landing page messaging, informed by sales, rectified the issue, leading to a 30% increase in qualified sales opportunities within a month.

6. Invest in Continuous Learning and Skill Development

The marketing world moves at breakneck speed. What worked last year might be obsolete next year. To truly improve, you and your team need to be constantly learning and adapting. This isn’t just about reading blogs; it’s about structured education and experimentation.

Actionable Step: Allocate a specific budget for professional development. This could be for online courses from platforms like Udemy Business or Coursera for Business, industry certifications (e.g., Google Ads certifications, HubSpot Academy certifications), or attending virtual conferences. Encourage each team member to complete at least one new certification or course per quarter.

Pro Tip: Create a “lunch and learn” series where team members present what they’ve learned from a course or conference to the rest of the team. This not only reinforces their learning but also disseminates knowledge across the department, fostering a culture of continuous improvement.

Common Mistake: Believing that once you’ve mastered a particular channel or tool, you’re set for life. That’s a dangerous mindset. Algorithms change, new platforms emerge, and consumer behavior shifts. Stagnation is the enemy of progress in marketing.

To truly improve your marketing, you must embrace a relentless cycle of auditing, testing, refining, and learning. It’s not about grand gestures; it’s about consistent, data-driven action that compounds over time.
