You should preferably using LSI keywords. The on-site SEO and content should be well written. The link building process should remain the same. You could do some good internal link and also build backlinks to some of your high search volume pages too.
Good Luck!
The articles' length depends from the niche and if you make review (for example) you need to write it really long (for conversion rate and for Google experience).Hi, and thank you for your reply. Could you simply explain what LSI keywords are? And what length articles do you recommend ?
It does not matter with single or multiple niche, techniques are same for both. You can do some guest post and web 2.0 properties to generate backlinks, you can also generate backlinks from PBN.
Are those niches really not connected in any way? If they are, I'd try a silo structure approach.
Hi, all the niches are connected and has the same keyword for example niche1+tool , niche2+tool.
When should I start ranking the new multi niche site? Should I wait some time first, I am adding unique hq articles almost every day.
