How to say a specific link is bad or good?

After this May Core update from Google. People are very curious regarding this. Large post pages with very long loading time are effected negatively. What's your say in this?

I have seen some blog posts regarding this. But they only expresses the individual blogger's personal POV.

In general what problems does a newbie or an advanced user can face, its not represented well.

So, please share your views on which plugins to avoid!!! And also if possible share why?

I am seeing a lot of discussions and debates regarding this rubbish type results of Google. And it not limited to closed forum groups. Now these discussions can be seen on reddit and also in social networking sites.

As my subject line tells everything. I am not going to try and explain.

I am just frustrated with Google now.

Sites which are hosted in free platform such as the blogspot or wordpress with ridiculous link profile. Their links are only from spammy sites which anyone can confirm are ranking high and our good sites are no where to be found.

Its not that these sites have very good content. They have content copied basically from other sites and pasted in their ones.

How can one successfully opt out of adchoices? Every time I do that, ads comes back after some time.

Found atleast 10 expired domains. But don't know how to choose from them!!

They are all relevant in our niche.

I am looking for any guide or tutorial. But all I have found is talks and discussions.

Hey guys!!

Is it preferable to put exact match kw's in headlines or just put some match kw's with keeping meaning of header same?

The reason I am asking this question because will putting exact kw's put you in the suspect list of Google. Won't they will look into you as you were trying to manipulate the SERP's?

Its simple now. If your site doesn't get much traffic from US then you won't get much revenue.
