PPC Basics Refresher
Before getting into keyword research, it’s worth understanding the fundamental structure and mechanics of PPC. Here’s the lowdown:
1 What is PPC?
Pay-Per-Click (PPC) is an online advertising system in which advertisers pay each time someone clicks on their ad. It is a method of paying for visits to your website, as opposed to trying to “earn” those visits through organic means
2 Popular PPC Platforms
There are many platforms that can host PPC campaigns. Each has its own targeting capabilities, ad types, and audience:
- Google Ads – The most popular, including Search, Display, Shopping, and YouTube advertising.
- Microsoft Advertising (Bing Ads) – A good fallback to Google with frequently cheaper CPCs.
- Facebook and Instagram Ads – Great for image ads and behavioral targeting.
- LinkedIn Ads – Best for B2B targeting by job title, industry, or company size.
- Twitter/X Ads and TikTok Ads – Good for brand awareness and viral content marketing.
3 Must-know PPC Terminology
Understanding these terms is essential to running a campaign:
- CPC (Cost Per Click): How much you pay every time someone clicks on your ad.
- CTR (Click-Through Rate): The number of users who click on your ad divided by the number of users who viewed it.
- Quality Score: Google’s evaluation of your ads, keywords, and landing pages. Higher values result in better ad placement at lower prices.
- Ad Rank: Controls your ad position by bid amount and Quality Score.
- Impression Share: The total impressions your ads get compared to the total possible.
4 How PPC Works
- Keyword Targeting: You select appropriate keywords to show your ads when users search.
- Bidding: You specify a maximum bid you can pay per click.
- Auction: With each user search, there is an auction to decide which ads are displayed and in what order.
- Ad Delivery: If your bid and quality are high, your ad is displayed. On click, you pay.
- PPC is a balance of bidding, relevance, quality, and strategy. Being good at these fundamentals lays the foundation for successful keyword research and campaign success.
Why Keyword Research Matters in PPC
Keyword research is the key to every successful PPC campaign. Without it, you’ll end up wasting money on irrelevant traffic or losing high-converting opportunities. Here’s a closer look at why keyword research is essential:
1 Enhances Ad Relevance
When your keywords closely relate to what users are looking for, your ads become more relevant. This results in increased engagement rates, greater alignment with user expectations, and a better overall user experience.
2 Increases Return on Investment (ROI)
Targeting high-intent keywords and skipping low-performing keywords helps eliminate wasteful ad spend. Research-driven keywords ensure that you are allocating your ad spend to users that are most likely to convert.
3 Facilitates Intent Matching
Knowing the intent driving every keyword—informational, navigational, or transactional—allows you to optimize your ads and landing pages accordingly. This leads to higher conversion rates and fewer bounce rates.
4 Increases Quality Scores
Google and other ad networks favor relevant keywords and properly aligned ads with better Quality Scores. High Quality Score reduces your cost-per-click (CPC) and allows your ads to show up in better positions.
5 Facilitates Smarter Campaign Organization
With solid keyword research, you can organize similar terms into closely themed ad groups. This helps you write more targeted ad copy, control bids, and track performance at a more detailed level.
6 Avoids Keyword Cannibalization
If you are not strategic, several campaigns may end up competing on the same search terms, increasing your spend. A properly organized keyword plan prevents this overlap and keeps everything clear across campaigns.
7 Stays Competitive
Continuing keyword research keeps you informed of new opportunities, tracking trends, and getting ahead of competitors who might be bidding on the same terms.
Now that we’ve shown its significance, let’s learn about the various types of PPC keywords.
