Hello Everyone,
I'm a digital marketer and new in the field. While searching about SEO techniques I get some black hat techniques.
So, the question is can I use these techniques to my projects? Is it harmful?
Please share your experiences.

All I can find regarding link building and link building tactics to get real quality backlinks is by guest posting.

The internet is flooded with discussions about how guest posting can help one webmaster to get quality backlinks.

So, my query here is that is it really the only way or there are some other methods too?

Why do certain pages have high bounce and exit rates?

Recently, I am facing many problems with analytics. In many cases, as it can't even filter out bots from regular visits. And also there is the fact that Google has decided to flood the metrics (I don't know how?!) by bot-direct traffic.

So, I talked to some of my fellow site owners regarding the performance of analytics. Turns out I am the only one using analytics as a sole stat viewer.

What service do you guys use along with anaytics?

Yesterday was bad. And today is even worse. Where all the clicks are going?

I am seeing many keywords ranking well in the first pages then where is the traffic?

I am not talking about worthless or garbage comments or spammy ones. I am talking about comment that are well written and thoughtful. Will those tons of comments effect the site's SEO somehow?

How much a full site audit can cost? The site is 20 pages or so. And doesn't have much complex elements. It's a simple blog actually.

I know its a bit odd query. But I was wondering which niche would be it?

And also will most direct advertisements means more opportunities for the niche, right?

I know a great many tools to design banners. It's just that I haven't done it personally.

So, I am mulling to hire webdesigner here. What should I do?

If a site's theme is heavy and takes a lot of time to load. Does it mean that it effect the site's SEO negatively?

Many webmasters say that it has effect. But yet I see a lot of site who takes a lot of time to load still manages to rank very high.
