In one representative breakdown, fixing landing page and form issues alone cut cost per lead by roughly half, without any change to ad spend or bidding strategy.<\/div>\n<nav class=\"bx-toc\"><strong>On this page<\/strong><\/p>\n<ul>\n<li><a href=\"#the-formula\">The formula behind cost per lead<\/a><\/li>\n<li><a href=\"#the-breakdown\">A line-by-line breakdown<\/a><\/li>\n<li><a href=\"#where-the-gain-came-from\">Where the biggest gain actually came from<\/a><\/li>\n<li><a href=\"#applying-this\">Applying this to your own numbers<\/a><\/li>\n<li><a href=\"#faq\">FAQs<\/a><\/li>\n<\/ul>\n<\/nav>\n<h2 id=\"the-formula\">The Formula Behind Cost Per Lead<\/h2>\n<p>Cost per lead is not one number, it is the output of three numbers multiplied together, working against each other. Cost per click, click-through rate on the ad, and conversion rate on the landing page all combine to produce the final figure. Most businesses only look at the final number and miss which of the three inputs is actually the problem.<\/p>\n<p>Breaking the formula apart is the only way to know whether a high cost per lead is an auction problem, an ad problem, or a page problem, and each of those has a completely different fix.<\/p>\n<h2 id=\"the-breakdown\">A Line-by-Line Breakdown<\/h2>\n<table class=\"bx-table\">\n<thead>\n<tr>\n<th>Metric<\/th>\n<th>Before Fixes<\/th>\n<th>After Fixes<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Cost per click<\/td>\n<td>\u20b928<\/td>\n<td>\u20b926<\/td>\n<\/tr>\n<tr>\n<td>Click-through rate<\/td>\n<td>3.1%<\/td>\n<td>3.4%<\/td>\n<\/tr>\n<tr>\n<td>Landing page conversion rate<\/td>\n<td>1.4%<\/td>\n<td>2.9%<\/td>\n<\/tr>\n<tr>\n<td>Effective cost per lead<\/td>\n<td>\u20b92,000<\/td>\n<td>\u20b9975<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Notice how small the change in cost per click and click-through rate was compared to the change in landing page conversion rate.
