Google Manufacturer Center can be most valuable for brands that: Have a lot of collateral surrounding their products such as positive third-party reviews. Convert customers mainly via brick and mortar, letting their online retailers pick up the online demand for their products. Have products that are usually part of a bigger basket. Items that are expensive to ship relative to product cost sometimes do better at ecommerce retailers since they can become part of a bigger basket. Are retailer agnostic – don’t care who sells so long as the sale happens.

It is possible for a manufacturer to participate in both Merchant Center and Manufacturer Center. Information provided via Manufacturer Center will not affect the listed retailers or the sale price of products advertised on Google via Merchant Center. If a manufacturer would like to advertise their products for sale, they can do so via Merchant Center.

Block ads to prevent sophisticated attacks that masquerade as images. Use VPN for end-to-end encryption whenever you’re working at public WiFi hotspots to prevent session hijacking and MITM attacks.

While it’s true that edits are tied to your whole Google account, it is the consistency and reliability of your edits that truly give you influence. There are a series of checks and balances that allow factual edits to grant you more trust. I have seen edits from a Level 3 guide get accepted immediately and those from a Level 8 guide go into a ‘not applied’ status immediately

Since the criteria to become a Local Guide is entirely based on the quantity of actions taken (rating/reviewing a business, suggesting business edits, etc.) rather than quality, it’s extremely common for bad actors to become a Local Guide

If you feel the link is a bad link then I'd disavow the link. I'd see if you can see the page linking to you via Google cache or via archive.org

you can't hide your disclosure on a separate page or after three screens of scroll. You have to make your disclosure within close proximity to the "triggering claim" - that is, to the statement or endorsement that causes you to have to make a disclosure.
