Paid Advertising

The fundamental distinction between SEO and PPC lies in the method of acquiring traffic. SEO (Search Engine Optimization) focuses on earning organic, unpaid traffic through strategies that improve a website’s ranking in search engine results pages (SERPs). This is a long-term strategy. PPC (Pay-Per-Click), on the other hand, is a paid advertising model where traffic is acquired by bidding on keywords to place ads at the top of SERPs. This provides immediate, but non-organic, traffic.

In a PPC campaign—particularly on platforms like Google Ads—keyword bidding operates as a real-time auction. The bid is the maximum amount an advertiser is willing to pay for a single click on their ad. However, the actual cost-per-click (CPC) is determined by a complex algorithm that considers not only the bid, but also the ad’s Quality Score, which is a metric that assesses the ad’s relevance, click-through rate (CTR), and landing page experience. The Ad Rank is calculated by multiplying the bid by the Quality Score. The ad with the highest Ad Rank wins the auction.

Quality Score is a crucial diagnostic tool in Google Ads, rated on a scale of 1-10. It is a key determinant of Ad Rank and cost-per-click (CPC). A higher Quality Score indicates greater relevance and can lead to a lower CPC and better ad positions. It is influenced by three main components:

• Expected Click-Through Rate (eCTR)
• Ad Relevance
• Landing Page Experience

Optimizing these factors is essential for maximizing ROI.

A/B testing, or “split testing,” involves running two versions of an ad (A and B) simultaneously to see which one performs better. In a PPC context, this can mean testing different headlines, descriptions, or calls-to-action (CTAs). The two ads are shown to similar audience segments, and their performance is measured using metrics like click-through-rate (CTR), conversion rate, and cost-per-click (CPC). Statistical significance is used to determine which variation is the clear winner, after which the losing ad is paused and the winning ad is scaled.

A conversion is a specific action a user takes on a website that is valuable to a business. This could be a purchase, a form submission, a phone call, or a newsletter sign-up. Conversion tracking is implemented using a piece of code (e.g., a conversion tag from Google Ads or a custom script) placed on the conversion-specific page (e.g., a “thank you” page after a form submission). This tag fires when the user lands on the page, sending data back to the advertising platform to record the conversion.

A negative keyword is a type of keyword that prevents an ad from being triggered by a specific search query. It is a critical component of campaign optimization. Common examples of negative keywords include  “free,” “used,” and “DIY” (if you sell new high-products or perform services). Another example of negative keywords are nearby locations where you do not wish to do business or otherwise target for customers. These allow you to exclude irrelevant search traffic, reduce wasted ad spend, and improve the overall click-through-rate (CTR) and conversion rate by ensuring your ads are only shown to highly relevant audiences.

Lowering CPA involves a multi-faceted approach. Key strategies include:

• Improving Quality Score (lowers CPC)
• Refining keyword lists (by adding negative keywords and targeting more long-tail, high-intent keywords)
• Optimizing ad copy and landing pages to improve conversion rates
• Using bid strategies (like Target CPA to automate bids based on desired cost per conversion).
• Analyzing search query reports to identify new opportunities and exclusions

A landing page is a single, focused web page designed specifically for a PPC campaign. Its primary role is to convert visitors into leads or customers. A well-optimized landing page will have:

• A clear, compelling headline
• Concise ad copy that aligns with the ad
• Astrong call-to-action (CTA)
• A minimal number of distractions

A landing page’s relevance to the ad’s keywords and message is a key factor in improving Quality Score and conversion rates.

Bid strategies are rules that determine how bids are set in a PPC campaign. They can be manual or automated. Manual bidding gives the advertiser full control over cost-per-click (CPC). Automated strategies, like Target CPA, Target ROAS (Return on Ad Spend), or Maximize Conversions, use machine learning algorithms to set bids in real-time to achieve a specific campaign goal. The choice of strategy depends on the campaign’s objectives and the available data.

Remarketing—sometimes called “retargeting”—is a powerful PPC strategy that involves showing ads to users who have previously visited a website but did not convert. It works by placing a cookie on the user’s browser when they visit the site, which then allows the advertiser to display relevant ads to them on other websites they visit. This is an effective way to re-engage users who showed initial interest, increasing the likelihood of a conversion. It is often used with custom audience segments based on user behavior (for instance, users who viewed a product page but didn’t add it to their cart).
