How to Earn Money Blogging?

While starting a blog can be fun and help others, it can also offer you an income. But by no means is this a get-rich-quick business. If you want to create a site that makes real money, be prepared to put in countless hours of work.
As your blog gains popularity and credibility with readers, your articles will start to rank higher on search engines, which would likely result in higher site traffic. And more visits could mean more money if your blog is properly monetized.
Here are some common ways to monetize your blog.


Affiliate marketing
With this type of marketing, you can earn a commission for every product you refer a reader to. It basically works like this: let’s say you apply to an affiliate program and get approved. You’d then mention a product in a post and link to the online store featuring the product. If a reader clicks on the link and buys the item, the program will give you a piece of the sale.
One popular example is the Amazon Associates program. Once you’re accepted into the program, your commission could range from 4 to 8.5%, depending on how many products are bought in a given month (the more sold, the higher your rate). So helping to sell $4,000 worth of women’s shoes, for example, could mean $160 to $340 in revenue.

Direct advertising

If your site is getting lots of traffic, it’s prime real estate for advertisers. You can generate income by putting direct advertisements, such as banner ads, on your blog.
One way to do this is by signing up with an advertising service, such as BuySellAds, where you can sell space on your blog. How much you earn from direct ads ultimately depends on the average number of views per month that your site pulls in.

Display advertising

Or you may choose to use display advertising, which follows a different revenue model. The most popular option for bloggers is Google AdSense, as it’s relatively easy to implement and free to use.
It works like this: advertisers choose which keywords they’d like to advertise on. For example, an online florist would likely choose to buy an ad that contains the keywords “flower pots” or “gardening tools.”
After you install AdSense on your site, it automatically displays relevant text and image ads based on the topics of your blog posts. So if your blog happens to be about planting roses, the site will likely display the advertiser’s gardening tool ad, instead of something unrelated.
When a visitor clicks on the ad, the advertiser will pay you a fee; this is known as the “pay-per-click” system. The average cost-per-click (CPC) is how much an advertiser is willing to pay for a click on the ad. This depends on how valuable the keyword is to advertisers, who bid on keywords to determine the price.
Your AdSense earnings depend on how many page views your site gets, plus the ad click-through-rate (CTR), which is how often readers click on the ad. For example, if your site gets 1,000 views month and your CTR is 2%, with an average CPC of $2, you’ll make $40 in Adsense revenue a month.

Video blogs

Video blogs (or vlogs) are not only fun to make, but also potentially profitable if you get a strong following. Building a loyal viewership by consistently uploading engaging clips is vital to your success.
Joining YouTube’s partner program is a popular monetizing strategy among vloggers. Once you produce and submit a video, Youtube places ads inside or near the video, and you’ll earn revenue every time someone click or views the ad. Payments are then made through a Google AdSense account.

Electronic books

An electronic book, or e-book, displays your expertise on a topic, increasing your credibility with readers and potentially increasing your income.
With smartphones and iPads exploding in popularity, more and more people are reading content online. In fact, the percentage of adults reading e-books increased to 28% in 2013 from 23% at the end of 2012, according to Pew Research.
There are a few places you can sell your e-book. One is through Amazon’s Kindle Direct Publishing platform, where your e-book will be available to buy via Kindle devices. Other options include PayLoadz, Lulu, Smashwords and BookBaby.

So how much money can you really make blogging?

Well, in a recent survey of 1,500 readers, ProBlogger.net found that roughly half made less than $99 a month from blogging, while about one in five made between $100 and $499. Less than 10% made between $1,000 and $9,999. And those in the top income brackets have been blogging for at least four years, according to the site.
Remember, blogging isn’t a get-rich-quick business; it’s more like starting a company from the ground up. While a few people make enough money doing it to quit their full-time jobs, the majority of bloggers only earn enough for the occasional fancy dinner.

How to apply for Fun Google Adsense Raiders?

Google Adsense is the most important survival tool for Google, is the world's choice for webmasters to make money, I believe we are not unfamiliar to this.
Before very long years, many webmasters are using Google Adsense to make money, but this year, due to reasons known to all, Google's full line of products in the domestic one banned.
For ordinary people, this means that no circumvention can not use Google, and for the owners, the consequences are serious for the registration and use of multi --Google Adsense have been severely affected.
By this time, the domestic Baidu Union, Sogou Union also strong attack, the major giants have hope in this post-Google era in this industry which ad network share. For ordinary owners, we only need to see the two issues is enough: Do not use Google Adsense? If you do, how should I use?
Not to use Google Adsense?
Answer this question can not be generalized for small sections of the site - such as Lu Songsong blog, because readers are very vertical, so there will certainly be many advertisers are willing to direct advertising, under such circumstances, of course, without any ad network. The more sites - those visitors randomness larger sites, those sites traffic uncertainty, I think it should still use Google Adsense. The following reasons:

1. Price High: Google Adsense unit price is definitely regarded as one of the best in recent years, although the decline, but also the absolute rejection of the domestic league a few blocks, especially doing overseas traffic sites.

2. Do not tax deductible: Google's commission is paid by the US company, paid to you is not tax deductible, of course, give the Bank of China received some of the costs that you go to the bank, but compared to other alliances frequently ten percent tax fee, Google still kind too much.

3. Simple: Google Adsense is very simple to use, if you tried other ad networks, Google Adsense you will marvel at the ease of use and simple, such as Google Adsense does not require registration, but all domestic ad networks are a mandatory requirement record.

4. Restrict less: Many ads Alliance has certain requirements for the type of site traffic, etc., and use Google Adsense, you then do not worry as these, because it's very few restrictions. Various websites can use Google Adsense.
5. Custom: You can display ads do custom processing, in order to fully fit your website style. Many other ad networks or no custom style options.

6. Powerful Reporting: Data Report Google Adsense's best in the world, which allows you to have a sufficient basis to optimize advertising and website content.

7. Optimizer: If only the data reports, that's not much use, but Google Adsense provides some columns tools allow you to make to maximize their own interests.

8. plenty of advertisers: Google Adsense advertisers around the world with the best, which makes you able to find adequate adaptation to your website content ads. This can improve the click-through rate, even for the user experience is also beneficial.

9. Smart Adapter Advertising: Google Adsense algorithms and powerful enough advertisers to ensure that the contents of intelligent adaptation advertising. This means that regardless of the user from any countries and regions, from any industry, Google Adsense can show ads against him, which also means a higher CTR and more user-friendly experience.

10. Payment Credit: Small ad networks are often not reliable, but Google Adsense you can be absolutely assured. For home owners can take advantage of Bank of China to extract dollars.
Besides Google Adsense There commission, high speed and so on. Since there are so many advantages of Google Adsense, then, how can we use it?
The first skill is the wall.
Over the wall is a new generation of Internet users must master the skills, you can use a proxy, Goagnent, VPN, or the like shadowsocks way over the wall, specifically Baidu, anyway, many ways to pay there, there are also free.

Method
First: Apricot (surcharge)

Second: xskywalker browser

Third: http://www.freevpnsakura.com/ set VPN, more trouble. Each time will change the password
After climbing over the wall, we came to Google, sign up for a Google account, such as Gmail account, which is a pass Google services.
Once you have an account, we entered I found Union Google Adsense account registration, fill in the information.

I was previously applied, so there will be those, if you are a first application, and honestly fill out the contents on the line. Finally, click on submit an application.
Google will complete your application within one week, if the application is successful, you will own a Google Adsense account.
You might call me, this is where the new play Well, we are doing so ah. I'm talking about new ways is Google Adsense cooperation in China only authorized service providers - I found alliance.
If you're like me on Google Adsense illiterate, do not know how to use, do not know optimization. But still want to use Google Adsense, then I found the league might be helpful to you.
In an official partner of Google Adsense page (http://www.google.com/adsense/start/partners/partners.html), we search in China, to find such a site.
After understanding the trial found that this site may make Google Adsense glow of life is not the same, especially in the context of the domestic network.
I am not familiar with the search alliance could help Google Adsense Webmaster deploy and optimize Google Adsense ads, Google Adsense although very simple, but after all foreign products, localization doing enough, I found it a very good league made ​​up for it provides grassroots webmaster can understand, analyze data to use.
Moreover, under the authorization of Google, I found a website advertising in the league can also analyze various issues, complete the targeted optimization. Also said to help websites achieve free mobile browser adaptation, in the mobile phone style added advertising, but I have not tried.
The key, I found through alliances (adsense.woso.cn) platform, Google AdSense is no longer required to apply for registration over the wall, they have a professional team responsible for one of the guide, and one day be able to down the account (this is really efficient).
Use the site to make money, become more and more difficult, more and more simple, on the one hand, because of the Internet bubble, the flow more and more worthless, on the other hand, a variety of excellent products from all aspects to increase individual value traffic. This increases the traffic really want all sites, but so that each flow have played the greatest value - the user experience and select ad networks, optimizing the use of tools, but more critical.

前港督稱中國沒違反中英聯合聲明

前港督衛奕信在週四出席英國上議院辯論香港問題時,認為香港警方處理佔中措施適當,
讚揚警方維護法治,又認為沒有明顯證據證明中國違反《中英聯合聲明》。 
他又說被示威學生的熱情感動,除了個別事件,示威大部分是和平進行,認為部分要歸功於香港警方。 
代表英國政府發言的英國上議院發言人華萊士,也為香港特區政府維護社會法治辯護,形容香港警方的做法大部分適當,沒有直接提及所謂的香港警方施暴事件。華萊士還說,在政改問題上,英國認為不應訴諸於類似阿拉伯之春的街頭政治,而漸進的改革、磋商以及緩慢的進步才是較佳選擇。 (林智文 黃彩嬋)
