What Is Single Page Application / website (SPA) ?

WHY GUEST BLOGGING?

An SPA is an application delivered to the browser that doesn’t reload the page during use. Like all applications, it’s intended to help the user complete a task, such as “write a document” or “administer a web server.” We can think of an SPA as a fat client that’s loaded from a web server.

SPAs usually do many other things besides opening and closing a chat slider—like sending and receiving chat messages. We’ll omit such pesky details to keep this introduction relatively simple and brief. To pervert a famous saying, one can’t conquer SPAs in a day.

Guest blogging is a great way of getting in front of an already existing audience (the audience of the blog you are guest posting on) and spread the word about you and your expertise to new people outside your own circles.

For some time guest blogging was also famous for being a legitimate strategy to building relevant links back to your site. Matt Cutts (head of Google’s Webspam team) declared war on guest blogging for gathering links a while ago. Still, it seems that this is still working and you can still profit from the link back to your own site.

The user benefits of a well-written SPA

How to approach a guest blog opportunity (CONTACT, CONTENT, COMMUNICATION)

(An SPA can render like a desktop application) :- The SPA redraws the parts of the interface that need to change only as needed. A traditional website, in comparison, redraws the entire page on many user actions, resulting in a pause and a “flash” while the browser retrieves from the server and then redraws everything on the page. If the page is large, the server is busy, or the internet connection is slow, this flash can take several seconds or more, and the user has to guess when the page is ready to use again. This is a horrible experience when compared to the rapid rendering and immediate feedback of an SPA.

(An SPA can respond like a desktop application) :- The SPA minimizes response time by moving working (transient) data and processing from the server to the browser as much as possible. The SPA has the data and business logic needed to make most decisions locally and therefore quickly. Only data validation, authentication, and permanent storage must remain on the server, for reasons. A traditional website has most of the application logic on the server and the user must wait for a request/response/redraw cycle in response to much of their input. This can take several seconds, compared to the near immediate response of the SPA.

Build a personal connection :-
The best way to get a guest blogging opportunity is always to meet the blog owner in person. There are blogs, which officially take guest posts where rumors tell that it is virtually impossible to get a guest post in, without a personal reference. If you have a chance of meeting bloggers from your niche in person: grab it.
If you cannot meet bloggers in person, you might still be able to talk to them in social media. Do never underestimate the power of a conversation.
It is not always possible to get to know a blogger personally before you want to apply for a guest post. Do not despair. That is by far the more common case and it is still possible to be very successful with guest blogging.

Email or Contact form :
Probably the most common way of contacting blogs for guest posting opportunities is the direct approach via email or if you cannot find an email address use the contact form provided on the blog.
In any case, you should definitely check first if the blog has guidelines for guest posts, look them up and keep as closely to the stated requirements as you can.
I recommend to write a perfect post which you want to submit and send this finished post with your application. Not all guest posting guidelines suggest this, some ask you to send a short outline of your post idea.
