And if you really want to know what are the most important, relevant pages to get links from, forget PageRank. Think search rank. Search for the words you’d like to rank for. See what pages come up tops in Google. Those are the most important and relevant pages you want to seek links from. That’s because Google is explicitly telling you that on the topic you searched for, these are the best.
Keyword research for PPC can be incredibly time-consuming, but it is also incredibly important. Your entire PPC campaign is built around keywords, and the most successful Google Ads advertisers continuously grow and refine their PPC keyword list. If you only do keyword research once, when you create your first campaign, you are probably missing out on hundreds of thousands of valuable, long-tail, low-cost and highly relevant keywords that could be driving traffic to your site.
Nearly all PPC engines allow you to split-test, but ensure that your ad variations will be displayed at random so they generate meaningful data. Some PPC platforms use predictive algorithms to display the ad variation that's most likely to be successful, but this diminishes the integrity of your split-test data. You can find instructions on how to ensure that your ad versions are displayed randomly in your PPC engine's help section.
If the value of a lead or engagement is a bit unclear, I recommend you take a close look at the lifetime value (LTV) of your customers. Don’t just think about how much profit they’ll bring in on the first sale, consider how much your average customer spends over the lifetime of their relationship with you. Compare this against your conversion rate and you’ll be able to better assess how much you can afford to bid.
