Most businesses that outsource content marketing to us expect a content calendar first. They want to know how many posts we'll publish each month, which topics we'll cover, and how soon the traffic will show up. Those are fair questions. When a content marketing agency takes over a site that already has years of blog posts on it, though, the first job usually isn't writing anything new. It's going through what's already there.
That can feel like an odd way to spend the first few weeks. You hired a digital content agency to write, and here we are reading your old posts. We get it. We'd still rather fix the pages that are holding your site back before we publish more content on top of them.
What Does a Content Marketing Agency Look at First?
We start with a full content audit. We pull every blog post, guide, and resource page on the site and line each one up against its data in Google Search Console and GA4. We look at impressions, clicks, average position, time on page, and whether the post has ever led to a sale or a lead.
Patterns show up quickly. Any content marketing agency that has done this a few times knows the usual suspects, and most sites have the same handful of problems.
Some posts get plenty of impressions but almost no clicks. That tells us the title and meta description aren't giving searchers a reason to choose that result. Some posts have zero impressions after two years online. That usually means Google has evaluated them and decided they aren't worth showing. And on almost every site that's been blogging without a plan, we find three or four posts chasing the same keyword.
That last problem is called keyword cannibalization, and it is one of the most common issues a content marketing agency finds in an audit. Each new post on a topic you've already covered splits the signals Google uses to decide which page should rank. So instead of one strong page, you end up with four weak ones that keep trading places on page two.
Why Would a Content Marketing Agency Delete Anything?
More pages don't automatically mean more traffic. Search engines crawl and evaluate the whole site, and a pile of thin or outdated posts can drag down how they view everything else you've published. If half your blog is 400-word posts from 2019 that nobody reads, that's part of the picture Google has of your business.
Deleting is rarely our first choice, though. When a content marketing agency recommends removing a post, it should be because that post has no traffic, no backlinks, no conversions, and no realistic path to becoming useful. Even then, we redirect it to the most relevant page so nothing breaks.
Clients sometimes push back on this part, and we understand why. Somebody wrote that post. Maybe it was the founder, back when the company was three people sharing one office. Most people hire a content creation agency to add pages, not take them away. In our experience, nobody misses it, and the posts that remain do better without it.
How Do We Decide What Stays and What Goes?
Every post from the audit ends up in one of four groups, and this sorting is built into our content marketing services from day one.
Keep. These posts already rank, bring in traffic, and convert. They get light updates at most. We refresh old stats, fix broken links, and add internal links to newer pages so they pass some of their strength along.
Refresh. These cover the right topic but don't deliver. Maybe the post is thin, maybe it answers the wrong question, maybe the information is out of date. We rewrite them using the same approach we use for new content, which we've laid out in our guide on how to structure a blog post for SEO. Refreshes are often the fastest wins in the whole project because the page is already indexed and may already have a few backlinks.
Merge. This group handles cannibalization. We pick the strongest URL in each cluster, fold the best parts of the competing posts into it, and redirect the rest. One thorough post that fully answers a question usually outperforms four overlapping ones that each answer part of it.
Remove. No traffic, no links, no purpose. These come down, with redirects wherever there's a sensible place to send people.
What Happens to Traffic After the Cleanup?
Sometimes it dips first. If we remove or merge 40 posts, total impressions can drop for a few weeks because those pages were showing up for searches, even if those searches were never going to turn into customers. That's normal. Any content marketing agency worth hiring should warn you about it upfront, and we always do, so nobody panics when the chart wobbles.
After that, the numbers that matter start moving. On our SEO campaigns, technical fixes and page level changes like these can start lifting performance within four to eight weeks. Merged pages climb because they're no longer fighting each other. Refreshed titles pull more clicks. Time on page goes up because people are landing on posts that actually answer their question. For our B2B content marketing agency clients, we watch organic leads closer than any traffic chart.
It also gives new content a better starting point. Every post we publish from here lands on a site that search engines already trust more. And because we're an expert content agency with real writers doing real research, those new posts hold readers longer, something we tracked in our own case study comparing human written and AI generated content.
What Should You Expect From a Content Marketing Agency in the First 90 Days?
Here's how the first three months usually go.
In month one, we run the audit, sort every post into its group, and build the marketing content strategy around the gaps we find. You'll see exactly which posts we plan to keep, refresh, merge, and remove, and why.
In month two, we carry out the merges, redirects, and refreshes. We also start publishing new posts that target topics the audit showed you're missing entirely.
In month three, new content production picks up its regular pace, and we have early data to compare against where you started.
If a content marketing agency wants to jump straight to publishing ten new posts a month without asking what's already on your site, it's worth asking them why. New content matters. It just performs better when it isn't competing with your own forgotten posts, and sorting that out is the first job of any good content marketing agency.
