Going to start new blog

it all depends on you my friend and what you want to write about and build a site on. Start with your keyword research and make sure that you get search volume and low competition.

You should create your blog based on what people might need a solution or an answer for. It must be a problem solving blog to create stickiness and repeat visitors. It is up to you, but start with something that you are comfortable with, may be happy lifestyle, being wealthy, better relationship, health and fitness, parenting and trouble child etc...

The main thing is getting started right now

The most important thing, in my opinion, as to whether or not a site is successful or not is at this stage right here and I think most newbies fly right by it.

You need to learn a lot more about market and keyword research than anyone who really cares about the site's success can post in a single forum post.

You need to find a market that is both profitable and reachable by you if you want this site to ever really make you any money.

You can put the same amount of time and money in a site that makes you nothing or a site that makes you money almost immediately.

This step of the process of researching what your topic is should take the most time if you want to be profitable.

Most of the posts on this forum and elsewhere where posters state they've been working on a site for months or years and haven't made any money is because they picked a topic that either wasn't profitable in the first place or was extremely profitable but also extremely competitive and they never get anywhere.

There is plenty of advice on this forum and in Google search for picking markets and selecting keywords.

I strongly advice you find out more before you proceed.

Well, first do a very quick research on the top keywords for google and choose wisely your favourite one and write down in notepad or any other software other very related to it. Then you should create a blog with a domain name (it would be great if you can write something very similar to your main keyword -> If you can write the same, it is perfect!)... And try to optimize your homepage for this keyword... Other keywords should be for different pages (articles!)

It's the most important you have to write good contents to attract visitors.

You can start your blog on any theme like health, travel, internet etc. all these are having good traffic
