11 Legitimate Ways To Generate Easily Backlinks

Search Engine Optimization is a major buzz these days. One of the most vital part of search engine optimization is to generate large number of quality backlinks. The term quality refers to many factors like do follow links,the blog/website which is linking back and the anchor text used for the backlink etc.

11 Legitimate Ways To Generate Easily Backlinks

Though we should keep in mind backlinks are not only meant for improving your search ranks but it also serves a greater purpose of bringing new readers to your blog. This is why in this post we will also focus on creating backlinks that may not be dofollow but is potential enough to bring traffic.Those are the following techniques that I had figured out,in order to create backlinks to your blog

1. Guest Posts

Guest posts are perhaps the most common way,that all bloggers adopt to gain genuine backlinks. These guest posts also serve as a doorway to our blogs. Concentrate on writing good informative articles for guest posts. If the visitor like’s your post then they will surely land on your blog for more good content. There are certain points that should be taken care of while writing a guest post.

Make sure you write something related to your blog content,this is because,if people visit your blog following the link they will look for content relevant to the topic of the guest post. And if they don’t find any,all your effort will go in vain & you will loose a potential visitor.

Try to deeplink your guest post with links in your domain & use proper anchor texts to do that. But please maintain relevance, just do not put them only for the purpose of deeplinking.
Also see : Why Guest blogging wins and why you should host a guest blogger

2. Commenting

Well we also know about this technique to achieve backlinks. This process on the other hand helps us create relationship with other commenter as well as the blogger who wrote the article. This is far more easier way to scatter your blog url everywhere. But just do not end up commenting “Great Post” or “It was worth reading” type comments. Because this may please the admin to publish the comment(thereby giving you a backlink),but none other future viewers will be impressed enough to visit your blog for more.

And there is yet another concern that most of the blogs do not provide dofollow links in comments. So the url in the comment just do not serve any purpose. So make sure you are commenting on a blog that do not assign a nofollow link & if they does then make your comment useful(adding value to the post) so that at least it serves as a gateway to your blog.

3. Related commenting

This is about commenting too. But as the name suggests it is a little bit different. I personally experimented this technique to get genuine visitors & not do follow backlinks. Let me explain. Take any of your post that you consider is really great to be talked about. Now using Google search,look out for posts that also writes about the same topic as that of your post. Open the 20 top ranked articles in the search results in tabs. Now for each of them, gallop through the article & post a comment talking something on it. Something means if it had missed something or you think some part needs more explanation.

Finally add these words, “you all could also refer to this post on your-selected-post-title” & put the link of the selected post on your-selected-post-title. These comments really works in bringing visitors. But I must remind you that, please do not spam as it hurts back in the long run.

4. Social Networking

This is the best part for any blogger. Doing work & making friends on the same time. I bet that we(bloggers) all are to some extent addicted to these social networking sites like,Twitter,Facebook,Friendfeed etc. But while we enjoy these we could spend a little insight to these in order to extend our blog. Look out for people who are equally interested. Join discussion boards related to your blog. Help people there & make friends. Suggest them with some informative links on your blog. If your post solves the problem then it is sure to get praised by someone making any other future reader to follow your link. Well importing feeds is a common way to talk about your posts as soon it gets published.

But this does not generate buzz for new bloggers as they do not own large reader base neither do they have the trust of too many readers. So as it infers, personal interaction always works better than automation. So import your feeds as well as interact with people & build your brand.

5. Bookmarking Sites

As like social networking,bookmarking sites like Digg,Stumbleupon,del.icio.us,Technorati plays a vital role in bringing lots of traffic to our blogs. We are mostly familiar with the pinging services that pings those bookmarking servers whenever we hit the publish button. I am not going to say much on that. Instead I believe in personal interaction. Participate in the bookmarking sites personally thereby building your authority there. This may not help immediately,but if consistent can bring immense traffic after a couple of months effort.

6. Article Submission

This is a not-so-old technique adopted these days. There are lots of websites that has a article trading system. For the sake of this article I will not talk about the money factor. This is similar to writing guest post. But it has a multiplied effect. You write an article & then submit it to the article directories. If it is selected it will get featured in their pages. Now you get a backlink from them. The multiplied effect comes into act when someone else is interested in your post.

These article directories lets others re-publish your articles depending on some condition i.e. they have to give the author(which is you) proper credits(your name, your blog name & a link to your blog). So you write once & it gets scattered without any more further effort. Here is a detailed guide on article marketing and answers to commonly asked questions.

7. Forum Activity

Forums are real places with real people. I mean to say this is a place where you can earn visitors that will follow you for long time. This is just because, in forums you get to help people & people really stay addicted to those who solves their problem. But how does it(forum) earn backlinks ?? There are two ways to do that
Simply look out for problems that people who are looking for a solution for and which you have already covered in any of your earlier articles. Just tell them in a nutshell there & put a link to that article of yours as a detailed discussion.

But if you face a problem that you haven’t covered up earlier in your posts but you know how to solve it. I suggest create a blog post with the solution first & then do as said in the earlier step. So you hit two target simultaneously.Create a post as well as earn visitors for it. Try to help others and solve problems. If you create a good resource and provide free support to people in the forums,they are bound to visit your blog and eventually they will become your fan. For further reading read 17 ways forums help you becoming a better blogger.

8. Conditional Re-publishing

This is an extension of the article submission(point 6) concept. Let others contact you if they want to re-publish your content. Give them conditions as in step 6. This will not harm you regarding content duplicity. As your url will be first indexed as the legal one. If there is an issue, it will be with him who has copied it. So forget about it.

9. Blog Networks

Though this is a very minor factor in increasing backlinks still I feel like mentioning this here. Join blog networks with high PR. This may not give you large amount of visitors but still the backlinking goal for SEO is fulfilled.

10. Plugin Development

This is strictly for those who have knowledge in coding. This works really well to get large amount of dofollow backlinks. This is achieved by putting a dofollow link to your blog in the plugin setup page. So whenever somebody downloads & uses this plugin the plugin resides within their domain & the backlink also resides there. So you get tons of backlinks in very short time(if your plugin is worth using). But this is bad in one way. Sometimes the search engines penalize you for sudden surge in backlinks which is of course not acceptable.

11. Conditional Link Love

 “Sharing is Caring”. This technique is not something I really rely upon & hence it is ranked as the last. Communicate with other bloggers in your niche & personally request them to put you in their blogroll & in return,you also do the same. This not only creates dofollow backlinks but it also lets you spread your brand as well as making relations in your niche.

Well I’m sure that this is not all but all I tried here is to give you a idea of what earns the most backlinks for you. I am sure you could find out many such ways yourself if you give it a try. I will be greatly thankful if you could share your ideas here which you think has earned loads of backlinks for you.

Retrotechtacular: Tube Amplifiers

It’s hard to beat this vintage reel for learning about how vacuum tube amplifiers work. It was put together by the US Army in 1963 (if we’re reading the MCMLXIII in the title slide correctly). If you have a basic understanding of electronics you’ll appreciate at least the first half of the video, but even the most learned of radio enthusiasts will find something of interest as they make their way through the 30-minute presentation.
Retrotechtacular: Tube Amplifiers
The instruction begins with a description of how a carbon microphone works, how that is fed to a transformer, and then into the amplifier. The first stage of the tube amp is a voltage amplifier and you’ll get a very thorough demo of the input voltage swing and how that affects the output. We really like it that the reel discusses getting data from the tube manual, but also shows how to measure cut-off and saturation voltage for yourself. From there it’s off to the races with the different tube applications used to make class A, B, and C amplifiers. This quickly moves onto a discussion of the pros and cons of each amplifier type.See for yourself after the jump.

Controlling Cheap, Awesome Christmas Lights

[James] was wandering around Walgreens after Christmas and found something very interesting – RGB LED Christmas lights that were individually addressable. At $6.50 for a strand of 15 lights, he just had to buy a few and figure out the control protocol. After all, who can turn down a big, cheap, controllable RGB LED strip?
Controlling Cheap, Awesome Christmas Lights
The packaging for these lights – apparently manufactured by BriteStar - includes a ‘try me’ button that cycles through different light patterns. This button is what initially tipped [James] off to the fact the lights on this strand could be individually controllable. Opening up one of the lights, he found exactly what he wanted: an epoxy blob, two wires for power, and three wires for the signaling.

After checking out this light with a scope and logic analyzer, [James] realized there was a very, very simple protocol going on. Essentially, the entire string functioned as a gigantic shift register, taking the values for one light and pushing it down the string. In looking at the protocol, [James] also discovered] these lights support 16 levels of brightness. Yep, RGB LED Christmas Lights with PWM for under $7. Can’t beat that.

[James] wrote an Arduino library to control these strings and put it up on Github. While your local Walgreens has probably already hidden these lights away in the back of the store, it might be worth asking around to see if they have any left.

Homemade Polariscope is Super Easy to Make

[Abhimanyu Kumar] was watching YouTube videos one day when he came across something called a Polariscope — After learning how it worked, he discovered you can make your own using household items!
First off, what is a Polariscope? Well, put simply, it is a device that can show you the photoelasticity of a clear specimen, which can reveal the stress distribution in the material! And it is actually really easy to make one.
Homemade Polariscope is Super Easy to Make
All you need to build your own is:
  • A polarized light source (any modern LCD monitor)
  • A transparent specimen (plastic cutlery, glass statues, plastic you can bend, etc)
  • A circular polarizing filter (the cheap 3D glasses you didn’t return at the theater)
Then just place the objects in the order shown in the diagram and start snapping some photos. This would be really cool for checking stress concentrations in a project — provided you are using some Lexan or acrylic!

Paintball Pistol Turned Sniper Rifle

There’s a huge price discrepancy between paintball pistols and paintball sniper rifles. So the [Fresh-Prints-of-3D] decided to print himself an sniper upgrade kit. He started with the classic Tippman 98 Custom pistol , which is a tried and true industry standard when it comes to reliable paintball guns. Using Sketchup he designed a side loading hopper adapter, a fixed stock, a magazine adapter, various brackets, and even a bipod fore-grip.
Paintball Pistol Turned Sniper Rifle

He then printed the parts out at his local hackerspace; Innovatrix Labs, which is in Northeastern Pennsylvania. A Portabee 3D printer was used for some of the first prototypes but the final parts were all printed on a large MendleMax2 which has a build area large enough for the entire fixed stock! The best part? He’s only been using SketchUp for a few months. Once the design and build is completely finalized he might release it under a CC license. 

It just goes to show that 3D printers are really breaking down various markets of overpriced plastic components — 3D printers only print trinkets? Pfft.

Clever Reed Switch Catches Thief

When [Abhimanyu Kumar] noticed money going missing from his small bookshop, he decided to set up a little trap to catch the thief. The problem was that the bookshop’s money was stored inside a cupboard in their house (back end of the shop), which meant that the culprit was likely one of their own employees. They already have a CCTV system installed in the actual store, and although he could simply add another camera in the house, [Abhimanyu] didn’t really want to do that.
Clever Reed Switch Catches Thief
He instead devised a simple security trap: dubbed the Jugaad Security System. In Hindi, Jugaad quite literally means “hack”. He added a small magnetic reed switch to the cupboard where the money is stored—well, was stored—which is then linked directly to an intervalometer. This then connects to an inconspicuous DSLR sitting on one of the work benches. He aimed the camera at the cupboard and, in case the lights are out when the system is tripped, set it to an extremely high ISO.


Three days later, during an especially busy day at the store, the camera snagged a few images of their would-be thief. Unfortunately, it was one of their own employees. A quick call to the police later and the thief confessed, returning the stolen money. Needless to say, they fired him.

Porting Contiki to the TI MSP430 Launchpad

For many years Contiki has been one of the main choices when it came to choosing an IPv6 over Low power Wireless Personal Area Networks stack (aka 6LoWPAN). It is developed by a world-wide team of developers with contributions from Atmel, Cisco, ETH, etc… and is open source. As most platforms to which Contiki has been ported are quite expensive, [Marcus] decided to bring the operating system to the TI Launchpad. For our readers that don’t know, the latter is based on a msp430g2452/2553 microcontroller, which only have 256/512 bytes of RAM and 16kB of ROM. As a side note, Contiki typically requires 10k RAM and 30k ROM.
Porting Contiki to the TI MSP430 Launchpad
[Marcus] therefore had to remove several features from Contiki: queue-buffering, energy estimation and regrettably uIP. His test setup (shown above) uses the TI CC2500 radio that can be found for less than $2 on Aliexpress, for which he wrote radio drivers from scratch. He also coded his own radio duty-cicling layer, as the one included in Contiki was too big.

Mooshimeter: The ‘Why Didn’t I Think Of That’ Multimeter

Despite how useful multimeters are, there are a lot of limitations you just don’t think about because they’re the way electronic measurement has always been done. Want to measure voltage and current simultaneously? Better get two meters. Measuring something in a dangerous, inaccessible, or mobile place? You could rig up a camera system to show the meter’s display on a monitor, you know.
Mooshimeter: The ‘Why Didn’t I Think Of That’ Multimeter
Mooshimeter is the better way of doing things. It’s a multichannel multimeter that communicates with your cell phone over a Bluetooth connection. With two channels. the Mooshimeter makes it easy to graph voltage against current to plot a beautiful IV curve on your smart phone.

Being a wireless multimeter means you can stick the Mooshi inside a robot and get instantaneous feedback of how hard you’re driving your motors. Far from being a two-trick pony, the Mooshimeter is actually a pretty good multimeter by itself. It can handle 600V and 10A with 24 bits of resolution. Here are the complete specs. The Mooshimeter is available for preorder here for $100 USD.
