Keyword research is a very imprortant part of SEO . I mainly consider 4 points - 1. Target Audience 2. Target Location 3. Target Search Engines 4. Business Type B2B/C2C . Can anybody tell me even more about it if u know?
You can also look for intitle and competition and the most important thing is the relevancy of the keywords towards your website because its a major factor that decides your ranking.
You may want to rely on spelling mistake keywords for popular websites (IF IT HAS RELATION, of course).
I recommend to follow people such as copy blogger and other highly reputable websites, then just second guessing. Its all about the keywords you choose before buying that domain name and making it into something. Theres something that most people dont talk about, which is semantic keywords. primary keyword: dogtraining After with semantic keyword: dog training camp, dog training tips, dog training These are topics that you can write about, to rank higher as well. Semantic keyword is end word that is attached "camp, tips, training"
