Nope

Sorry to hear that Jovo.

Perhaps the unknown reasons should become known reasons and should be investigated to determine why or could it be due to not keeping it simple and tried to manipulate the google algo?

I am confident with some digging around, you could find the solution.

I was just doing as you said, adding new texts on a regular basis, no tricks or manipulations and no changes of any kind, hard work only.

This is not the only example of my own, and I know that I am not the only one. Google is completely unpredictable in the past year or so, it makes all work useless overnight. I bought a house from this online business, but it becomes tricky now what to do after having such graphs.

Try to be patient. I've read numerous cases where sites have been affected just like this, but would regain their rankings after some time. It seems to happen when they do their algorithm updates which they recently had again. There appear at times to be collateral damage of good sites when Google seeks to weed out the more blackhat built sites. Then the ones that were collateral will often see their sites restored to former prominence after awhile. I wonder if the 100 day mark you mention might be a benchmark for a review by them. I've read that Youtube does something similar once one hits 300 views.

The 100 number was just the way of writing, the same is with my sites that have 600 posts or 1200 posts, all are affected but less drastically. I am in this 8 years and patience is my middle name.

The site shown above is as dead as dodo for many months, it will never recover, and I have three of them with the same situation, completely destroyed by Google.

The problem is that people assume what you assume, it will recover, or 'you must have tried to manipulate things'. Why should I? The sites were doing great, some for years, all basic teaching applied.

I see you are new here, so do not count on Google's eternal love, or you will safer.

Brutal graph. Good thing you have a portfolio of sites. Curious: Was this site mainly review-based?

Yes it looks terrible. This was "best of" type, the type that used to be very profitable a couple of years ago. But I have different sorts of sites, all are affected negatively even though some of them have never had any negative effect of Google algorithms for years. I was publishing like mad in all these years so it is natural to be irritated a bit when I hear that this is the right policy to succeed with Google. Well, it is not.

Products reviews business is dead no matter how you approach it, or at best, totally unpredictable, and only a fool can make long term plans based on it.

Yeah, Google is very unpredictable and I can understand your frustration. With the 'best of' sites, gotta be careful now! I put a lot of emphasis on question-style articles now (as per Partha's blogs), but still have a variety of reviews, best of's and info content, I'd say. And also YouTube. YouTube is a must!

800 to 1200 words

Thank you.

Keep in mind that it’s not just about the length. You need to do a great job of satisfying your readers query. That’s what Google wants to see. 😉

I know thank you.
