We wanted to position ourselves well in both paid and organic search, rank highly for our keywords, and improve our link building.

Multiple people recommended them to us.

Describe the project in detail.

After learning about our industry and our needs, High Voltage SEO compiled their ideas into a proposal and developed three separate implementation strategies (a four-, an eight-, and a 12-month plan). They're constantly offering us new services and currently handle Facebook advertising, Google ad creation and management, and new technology integrations.

Their company director handles the strategy, but they’ve also assigned a project manager and a coding resource, if we need one.

Compared to 2016, our website leads have increased by 48%. We rank in the first position for most of our keywords and our Google ads have certainly been successful.
