How to build a good backlinks?????

You could join Angele Edwards' backlink builder program. Essentially you get monthly packet of 30 dofollow links of high PR6- PR9 and step-by-step instructions with screen shots showing you exactly where and to how to leave your links on each site. I've had great success using her service.

join in forums, social bookmarking, socila networking,trade links, press release blogging, it will help you to have good backlinks.

I would suggest 4 methods that work well for me:

1) Article marketing. Write consistently and submit articles to directories every day. Every article that is accepted and published will gain you more back links.

2) Write good content and place them on your website or blog. If your content is good, people will share it on social book marking sites, forums, twitter... giving you more back links.

3) Comment on blogs. Visit blogs and read their posts. When you find the posts you are interested in, leave comments on it. Do not leave unconstructive comments. Respect the owners of the blogs.

4) Participate in forums. Contribute to forums and your signatures give you back links.

You're already building backlinks with each post using your signature box as above. Other methods include, writing tonnes of articles, blog commenting, and social bookmarking as mentioned by others above.

You can outsource link building to some really good "directory submission" sites. There are a few WSO's on this site that offer some link building packages that very reasonably priced.

Make sure you rotate the anchor text so that the same anchor text is not showing for every single link. Meaning, if your keyword is "humming bird feeder" you would want that text to change every so many links. ie. best humming bird feeder, humming bird feeders, feeders for humming birds, feeders humming birds and so forth. Not a lot but rotate about 5-10 of your best keywords that are similar and you will avoid looking spammy.

Oh and yes and write articles, press releases, social bookmarking, forum posting, create social profiles in social networking sites, youtube videos with links in description... to name a few possibilities

Good luck to you!

I am considering Angela links and this is the first negative comment I came across so far.

It depends on how you do it...

Angela didn't show you much details, but you should know it - whenever you put your link in the about me section or blog, put up a small article or some description about yourself (not the real you, but a virtual person), put a picture would help!

Just keep low profile and make your submission less "spammy"... this will greatly increase the stick rate and give you better result.

link at the post are backlinks is true, but if u add the "only" modifier, then it goes to not that correct. For example, the links from the do-follow backlinks are also goodbacklinks, and if they are relevent, then it will be better.
