Opt-in popup is a part of the Bloom plugin from Elegant Themes. It has been exclusively made for WordPress and enables you to add popups to your web site for email list building. The best part about this tool is that it comes pre-loaded with a range of templates from which you’ll be able to choose, and then you can customize colors, text, and fonts from there.
Solutions are tailored to meet your budget and success goals as much as possible, and websites have been delivered costing just a few hundreds dollars a month or for one of payments of a few thousand... it all comes down to our discussions, if you want a website that generates millions of dollars in sales your budget will obviously be bigger, if you're a small business then your goals and costs will be more realistic, at least to start with.
In this context, I guess each post can’t be thought of in isolation, but in terms of a mini content ecosystem that comprises of a great blog post optimised for on-page SEO, an upgrade to that post tailored for that specific content, various on-page email conversion points including an exit pop-up or similar -and then you combine all this with your off page link building and outreach efforts. That could be over 5,000 words of content all in just that one package.
