I reduced cost per conversion simply by removing broad keywords that weren't producing results. Less traffic actually meant better performance.
 
One of our campaigns achieved an 11% CTR on Google Search. Highly relevant ad copy and keyword grouping played a huge role.
 
One of my most memorable PPC campaigns was for a local plumbing company. The client had tried advertising before but wasn't getting quality leads. We rebuilt the Google Search campaign from scratch, focused on emergency service keywords, added location-specific ad copy, and improved the landing page. Within six weeks, the cost per lead dropped by around 45%, and the client started receiving calls almost every day. It wasn't a huge account, but seeing a small business grow made it one of my favourite projects.
 
One campaign I'll always remember was for a new eCommerce brand selling handmade products. We had a limited budget, so every pound mattered. Instead of targeting broad audiences, we focused on previous website visitors and lookalike audiences. Sales slowly increased week after week, and after three months the business was consistently profitable from paid ads alone.
 
I once managed ads for an online course creator. Instead of pushing people directly to purchase, we offered a free webinar first. That small change increased trust, generated thousands of email sign-ups, and produced far more sales over time than our original direct-sales campaign.
 
During last year's festive season, I managed Google Shopping campaigns for an electronics retailer. We spent weeks improving the product feed before launching. Better titles, clearer images, and more accurate descriptions made a huge difference. Sales exceeded the client's expectations, and the campaign became their best-performing holiday campaign ever.
 
I had great success with a Meta Ads campaign for an online store. Video ads performed much better than image ads.
 
My best campaign taught me to never stop testing. Every improvement helped increase conversions.
 
I had great success with Dynamic Search Ads after cleaning up the website content. It brought in valuable long-tail traffic that we hadn't targeted manually.
 
We combined Search Ads with remarketing, and the overall conversion rate improved much more than running either campaign on its own.
 
My best Meta campaign targeted existing customers with upsell offers. It generated excellent returns with a relatively small advertising budget.
 
A simple lead generation campaign outperformed all our expectations because the landing page was fast, clean, and easy to complete.
 
I worked with an online fashion store that struggled to make Meta Ads profitable. Instead of constantly increasing the budget, we spent time testing different creatives and audiences. One short lifestyle video suddenly took off, and the campaign reached nearly 8x ROAS during a holiday sale. That experience reminded me that creative quality often matters more than budget size.
 
The best campaign I've managed wasn't perfect from the beginning. In fact, it performed terribly during the first two weeks. Rather than giving up, we analysed search terms, paused weak keywords, improved the landing page speed, and rewrote the ad copy. By the second month, conversions had doubled while the CPA continued to decrease. That campaign taught me to trust the optimisation process instead of making emotional decisions.
 
My best PPC campaign taught me that optimisation never really ends. Regular testing, analysing search terms, refining audiences, and improving creatives kept performance moving in the right direction month after month.
 
One B2B software campaign stands out because the conversion numbers weren't massive, but the lead quality was exceptional. We only generated a handful of enquiries each week, yet several turned into long-term clients worth thousands. It reminded me that volume isn't always the best measure of success.
 
The campaign I remember most started off slowly but eventually became our highest-converting account after multiple rounds of A/B testing.
 
I learned that audience exclusions are just as important as audience targeting. Once we excluded low-quality traffic, performance improved immediately.
 
One campaign for an education client consistently delivered qualified enquiries below our target CPA for several months.
 
I once managed PPC for a dental clinic that wanted more appointment bookings. Initially, we targeted every dental service they offered, but the results were average. Later, we created separate campaigns for high-value treatments like dental implants and Invisalign. The leads became far more qualified, and the clinic eventually expanded its advertising budget because they were so happy with the return.
