SEO Expert to Troubleshoot Recent Ranking Declines

Hi all,

We've experienced some ranking declines since the recent Google updates, notably in November 2019 and the recent January broad update.

We have a selection of affiliate websites in various Home / Lifestyle niches.

We're looking for an expert with a strong track record, preferably somebody who has seen positive changes in the timeframe noted, to provide a fresh pair of eyes and look at where we might work to improve our search performance. Basically to come up with a checklist of actions that we can compare to our own evaluation.

Please reply with your experience and typical rate for a single site audit.
