Generally, build backlinks slowly but steadily, this is an ensured
way to improve in ranking. It takes time to get notice by Sir
Google, and at the very first you´ll experience your site dancing
like crazy.

Don´t start building 50+ links the very first week. I made the mistake
and building like 70 links a day, and this even though my website was just a
week old or so. Don´t do this.

Hi Tom,

It’s not the amount of backlinks which is important. I would focus more on where the links are coming from and how they are linking to you. Try to get your links in a way which looks natural to the engines and be careful who links to you and who you link out to.

This is just one of many factors the engines take into consideration when determining rank. A strong internal linking structure is important as well. The engines take this into consideration when ranking your site.

Hopefully your SERPs would improve. I would venture to guess that in most niches, 3000 backlinks in almost a year wouldn't get you anywhere near sandboxed.

If you can even get"sandboxed" by building tons of backlinks... (a debate for another day.)

I am on the side of guys that beleive that the number of backlinks built over time really matters less than most believe outside of highly contested niches. I think if you want results with your SEO you need to focus on

1. Keyword research
2. Domain purchase
3. onsite SEO ( overlooked by many even big companies )
4. Then build consistent and diversified streams of backlinks strategically to your site.
5. update your content regularly

Lastly just give this time and you will do fine there is no need to worry about sandboxing when you do the steps Google wants you to do properly everyone wins.
