90-Day Plan for Marketing Leaders to Master Any Website

Stepping into a new marketing role usually comes with a website you didn't build, don't fully understand yet, and probably don't have time to deal with in week one. That's normal. What matters is having a plan for when you do get to it, instead of reacting to whatever breaks first.

Here's a 90-day framework for getting a real handle on your website, broken into three phases: assess, fix, and build the case for what comes next.

Days 1-30: Assess

The first month isn't about changing anything. It's about understanding exactly what you've inherited before you start making decisions.

• Audit the technical basics

  • Run your homepage and two or three deep pages through Google PageSpeed Insights. Note the mobile score specifically.
  • Check whether the site uses smart content, personalisation, or progressive profiling, or whether every visitor sees the same experience.
  • Look at the footer for an agency credit, and check the blog's most recent post date. Both tell you whether anyone's actively responsible for this site right now.

• Understand who owns what

  • Find out who has admin access to the CMS, the domain, and any connected tools. Confirm you (or your team) actually have it; some agencies retain access even after an engagement ends.
  • Identify whether there's an existing retainer or support arrangement with a developer or agency, and what it actually covers.

• Map what's actually being measured

  • Pull whatever analytics or reporting exists and figure out what's actually being tracked: traffic, form conversions, pipeline attribution, or nothing beyond pageviews.
  • Note which pages get the most traffic and whether they're the pages you'd want prospects landing on.

• Talk to the team

  • Ask whoever's closest to the website day-to-day what frustrates them most. This is often the fastest way to find the real bottleneck, faster than any audit.

By day 30, you should have a clear, written picture: what's broken, what's underused, who's responsible for what, and where the biggest gaps are. Resist the urge to start fixing things yet; you need the full picture first.

Days 31-60: Fix the quick wins

Now you act, but selectively. This phase is about the fixes that are low-effort, low-risk, and immediately useful, not the big rebuild decisions yet.

• Handle anything actively losing you leads:

  • Broken forms, dead links, and expired offers should be fixed immediately regardless of anything else on this list. These are pure, quiet revenue loss.
• Turn on what you're already paying for: 
  • If smart content or progressive profiling aren't in use, this is usually a low-effort, high-impact fix. You're not adding cost; you're using what's already in your subscription.
• Clean up obvious drag: 
  • Compress oversized images, remove any tracking scripts or widgets nobody's using anymore, and check whether your tag manager and analytics are actually firing correctly.
• Establish basic ownership: 
  • Even if you're not ready to commit to a full support retainer, make sure there's a clear answer to "whom do I call when something breaks." An unclear answer here is how small issues turn into month-long outages.
    
• Set a baseline: 
  
  • Before any bigger changes, document your current numbers, traffic, conversion rate, PageSpeed scores. You'll want this for comparison once bigger changes start happening.

By day 60, the site should feel noticeably less fragile, even if it doesn't look dramatically different yet.

Days 61-90: Build the case for what's next

By now, you understand the site better than anyone else in the building, and you've fixed what was quick to fix. What's left is usually structural: the site was built on a template that's limiting what your team can do, or it doesn't reflect where the company's actually headed. That's not a quick fix, and it shouldn't be treated like one.

• Write down, specifically, what the site can't currently do that your team needs it to do. Custom layouts, campaign-specific landing pages, better personalisation, faster dev turnaround, whatever came up repeatedly during your audit and conversations.

• Slow load times have a measurable cost in lost conversions. A generalist freelancer taking weeks to make small changes has a cost in missed campaign timing. Wherever you can, put a number or a timeframe on the current pain; it makes the case for investment far more concrete than "it feels outdated."
• Decide whether you're looking at a full rebuild, a partial redesign of key pages, or bringing on dedicated development support. This doesn't need to be fully planned yet, but you should have a clear direction, not just a vague sense that "something needs to change."
• Come with your findings, your quick-win results as proof of momentum, and a clear ask. Leading with data from your first 60 days, not just opinion, makes this a far easier conversation.

The pattern worth remembering

Most of what goes wrong with an inherited website isn't dramatic. It's not one big failure; it's a slow accumulation of small gaps: features never turned on, small requests that took too long, nobody quite responsible for the whole picture. Ninety days is enough time to understand that pattern clearly and start reversing it, without needing to boil the ocean in your first week on the job.

If you're in the middle of this right now and want a second set of eyes on where you actually stand, we're happy to take a look, no pressure, no obligation.
