[Shanaki]

Hello guys,

Look i have here a stupid problem:

Can somebody tell how i can lose likes ? :))) you can check it live here: https://wo-men.ro/huse-iphone-6 i just put a bar in idea of Hello bar :))

With respect,
Shanaki

You can definitely lose likes a couple ways: users can unlike it OR people who liked it have deleted or otherwise had their profile deleted by Facebook itself. It's so few that it's likely some user cleanup on Facebook's end. I wouldn't sweat it.

Hey Erica, thank you for reply, and i am glad to hear answer from you. I usually read your posts on Moz.

But unfortunately , I have to contradict you. When we talk about a great number of likes , we can not put into account the possibility of mass unsubscribe or unlike/dislike. Chance for this to happen is too low. Even in a political showbiz likes will not acquire 0 (zero).

Somehow, not knowing how they(the likes) appeared again. You can check it here. 

I have a bar in style of hellobar.com , and i can say mine is upgraded :))

We can leave this like a mystery, but in fact i have some theory about it. I think somehow they have great connection with paid campaigns on Facebook. Maybe someone who really care about SEM, can confirm that. If a campaign stop, likes gone away ?

I've done Facebook ad campaigns and can definitely say that the likes don't go away when you turn them off.

You might try searching on the FB help community. You might be able to find someone having the same problem. (That's where I've been able to solve most of my FB problems.) There have definitely been times when FB's own reporting got screwed up, so it can be a check for that too.

I found out how you can lose social authority (and maybe more) on your website.

If you will read this post with 100% attention you will like it:

1. You need a ?utm_source 
2. You need a full page cache add-on like Lesti_Fpc

Result ? Incredible.

If you enter mywebsite.com/product1 and you like the page you give social authority to right page.
If you enter mywebsite.com/product1?utm_source.... and you like the page you give social authority to ?utm_source.... 
Well, most of us did not see that, cause facebook ads like page work good even you use a ?utm_source....
But if you use a full page cache, you have the chance that you index (cache) the page of product with ?utm_source

That why, i write there: How i can lose likes from Facebook on a category page. Mystery solved. Anyway i found out a way to explain the Facebook button to write on correct page and not on ?utm_source page and i removed the full page cache at the moment.

If you do not believe me you can check your self here: https://developers.facebook.com/tools/debug/og/object/
Like your page without ?utm_source and like it with ?utm_source

With respect,
