Thanks
@bae, really appreciate that

Can you tell me users you know here who post wp themes without any modification after buying or links to such wp themes?
Sorry mate, i only download stuff from innovativeSEO: http://www.blackhatworld.com/members/innovativeseo.639388/
I'm gonna be honest with you, WP sucks. It's useful for people to have a setup-ready website within a few seconds using the imported demos developers provide but you're very limited to that. For example, if you want a car insurance theme you'll download a theme someone developed with cars images and common layouts but that's it.
My best advice is to stick with only one theme and learn it very well. Learn how you can change backgrounds, fonts, colors, widgets appearance, content and sidebars widths, etc. Then use a page builder like Visual Composer (someone already posted the last version here) and use extensions to enchant it adding more shortcodes.
Take Newspaper theme as an example. Download it and install it without importing any demo. They've pre built templates for Visual Composer and implement several shortcodes for what they call blocks with sliders, grids, etc. Newstube is pretty cool but i've already developed 21 websites on this month with Newspaper and they're pretty beautiful. This is the flow with Newspaper i would recommend you:
- Install the theme
- Configure the theme: design colors, post and category layouts
- Install required plugins by theme
- Install Revolution Slider, Jetpack and Visual Composer Extensions Addon by Tekanewa, Contact Form 7, Mailchimp Widget
- If required install: Woocommerce, BuddyPress, BBpressand WP Cache
- Create pages: Homepage and Blog and set they as default on WP reading options . Terms of Use, Cookie Policy, About Us, Contact Us
If possible learn basic CSS and learn how to enchant the design when the theme you're using don't have an option for that (an example would be to add backgrounds to widgets).
That's it, you've a Wordpress website. To make it look like the themes you find in themeforest and others you'll have to get graphics: that's the secret to a successful website.
You'll need sliders with moving images and texts, you'll need banners, more sliders, more banners. I'm not a designer and i can do it only with GIMP, so install Photoshop, download free PSD already available everywhere on web, implement pretty icons.
I've video tutorials with Newspaper but only in Portuguese. But hey, you can trust me: read the documentation and learn your theme, mess it up locally and try every possible options. Get graphics and success is a matter of SEO.
