HOW TO RANK #1 SERPS?

Get lots of referring domains and lots of clicks (through a CTR service on BHW).

While it depends on the nice and the exact keywords you are going for, as a rule of thumb I think the chances of ranking in the top 3 without backlinks is nearly impossible.

If you can allocate some time to outreach it is advisable and will likely help in achieving your goal. An alternative, if you have the budget, is to work with an SEO freelancer or agency to assist you in building quality and relevant links.

Without backlinks you will never get permanent rank but you can ranked for some time by using social media or advertising.
