PPC (Pay-Per-Click) is a digital advertising model where advertisers pay a fee each time their ad is clicked. Essentially, you're buying visits to your website, rather than earning them organically. Google Ads and Facebook Ads are popular PPC platforms.

PPC works by bidding on specific keywords or target demographics. When users search for those keywords or match your target criteria, your ad may appear. If the user clicks on the ad, you pay a set amount based on your bid and the competition for that keyword.

PPC costs vary based on several factors like the platform, industry, competition for keywords, and targeting options. On average, Google Ads can cost anywhere from a few cents to several dollars per click, depending on how competitive the keyword is.

Quality Score is a metric used by Google to rate the quality and relevance of your ads, keywords, and landing pages. Higher Quality Scores can lead to lower CPCs and better ad positioning.

Ad relevance measures how closely your ad matches the search intent of users and how relevant it is to the keywords you're targeting.

A conversion is a desired action taken by a user after clicking an ad, such as making a purchase, signing up for a newsletter, or filling out a contact form.

PPC performance can be tracked using analytics tools like Google Analytics or platform-specific dashboards that track metrics like clicks, impressions, CTR, conversions, and ROI.

Negative keywords prevent your ad from showing for irrelevant searches. This helps you avoid paying for clicks that won’t convert.

CTR is the ratio of clicks to impressions, showing how often people click on your ad after seeing it. A high CTR indicates that your ad is relevant and engaging.

A landing page in PPC is the web page users are taken to after clicking on your ad. It's essential for converting visitors into customers.

Results from PPC can be seen almost immediately after a campaign goes live, but optimising for the best performance may take a few weeks of data gathering and adjustments.

To improve PPC Campaign ROI, you can focus on optimising your ads, targeting the right audience, refining your keywords, and improving your landing pages to increase conversions.
