When a business starts running search or social ads, the easy choice is to point them at the homepage. It already exists and it covers everything. That breadth is exactly the problem.
What a landing page does differently
A landing page is built for one audience, one offer and one action. It repeats the promise made in the ad, answers the objections that stop people acting, and asks for a single thing: a quote request, a call, a download. There's usually no main menu, because every exit is a way to leave without doing the thing you paid for.
Your website does a different job. It serves customers, job seekers, partners and the curious. It has to help people explore. Ad visitors don't want to explore; they clicked because of one specific message and they're checking whether you meant it.
When a dedicated landing page makes sense
- The ad makes a specific offer, such as a free consultation, a price or a guide.
- You're targeting one audience or industry that your main site only covers in passing.
- You want clean measurement of what the campaign produces.
- You're testing a new service before adding it to the main site.
When your website is fine
- Brand campaigns, where people search your company name and expect your site.
- You already have a focused service page that matches the ad closely: same wording, clear next step.
- The budget is small and a separate page would cost more than the campaign.
The match test. Read your ad, then look at the page it links to. Does the headline repeat the ad's promise? Is the action it asked for visible without scrolling? If a visitor has to hunt, you're paying for that hunt.
Either way, track it
Whichever you choose, set up conversion tracking before launch so you count enquiries, not just clicks. Without it you can't tell which ads, keywords or pages are earning their budget, and every decision after that is a guess.
