My conversion rate went from 2.5% to 8% just by including Facebook polls where SiteGround was rated #1, along with a few Twitter screenshots and Facebook conversations. Whether it’s Amazon reviews or Facebook polls, you NEED to include outside opinions – that’s why I don’t like collecting reviews on my website – they look biased. But you can use WP Review Pro to do this, allowing people to review the product/service on your site and get those review stars.
I expanded my SEO blog and started writing about hosting, cache plugins, and other relevant topics… while recommending SiteGround in each tutorial. I added social proof like the 34 Facebook polls where they were rated #1. Each tutorial was super detailed and tons of people found them helpful – many get 100+ visitors/day since great content = higher rankings.
