bookmark_borderInvoice Lambert isn’t a googler or Google Spy

The issue with the feedback on a weblog is that anyone can fake to be anyone and say something he needs. That's why most blogs have deleted feedback, aside from all of the spam that it’s a must to deal with. We’ve an issue right here with somebody claiming (not even pretending however performing as) a Googler, or a Google spy, or somebody with Google intel, who feedback right here.

This individual goes beneath the pseudonym of Invoice Lambert. He posts right here randomly, usually giving recommendation on Google-related points, suggestions that actual Google customers would by no means give. It additionally tries to foretell when Google will launch the updates. Typically he’s shut to those predictions and generally he’s off. With the prediction of fundamental updates, you do not need to be so sensible, Google has deployed them on the finish of the start of every quarter.

I've analyzed all Invoice Lambert's feedback on this website, checked out plenty of issues and I actually don’t suppose it's an actual googler or a spy. from Google. I don’t imagine it’s for a number of causes, together with that its IP addresses might be in Europe for just a few weeks, then in Asia, then in the USA. It stays with an IP tackle and it adjustments then. Sure, he can use proxies and varied strategies to cover his IP tackle, I perceive. One more reason is that it has already posted with completely different names with the identical IP tackle. The best way he talks isn’t like an actual Googler would communicate. An actual googler has no cause to spend as a lot time right here as him.

Oh and John Mueller from Google stated that he was not a googler this morning Twitter:

There are such a lot of SEOs who quote what Invoice is writing right here on varied boards, on Twitter, on search engine optimization blogs, and so forth. – it's not a great factor.

Is it potential that Invoice's character is an actual Google spy? I suppose. However when you ask me my opinion, I believe it’s simply dragging everybody and having enjoyable doing it.

My recommendation, suppose Invoice is only a troll and never a googler. Both manner, it doesn’t do you any good to imagine that he’s actually a googler.
