How We Determined the Best Website Optimization Companies

Selecting the top SEO agencies is not a precise science.  If we missed good SEO agencies, please contact us.

We identified the leading SEO companies by starting with their own website rankings. It makes complete sense that a good SEO agency would have their own website ranking well for the services they offer.

Next, we conduct a website audit to determine how well each SEO firm has managed their own website. The more site errors, the more likely the optimization company is not doing as much as they can to help optimize their own website.

We also take a look at their back-link profile to determine the quality of backlinks. Are backlinks from highly respected websites with related content, or are the links spammy from low quality sites?

Finally, we scan their website to see if they’ve won any awards for their SEO services. SEO honors and awards from third parties are a very good indicator that an agency’s website optimization services are effective and valued by those who nominate the firm. We do not consider customer reviews or testimonials because many SEO companies practice black-hat SEO techniques, including making false reviews and testimonials.
