Hey Ryan Yes, keywords ranking do drop in quantity. Always do checks to update your keywords. Personally, I do a monthly to quarterly check on these keywords to update on my site. You can have a look at my site https://www.corsivalab.com I feel you should put a focus on your content too. Make use of Moz Resources as they provide very good insights and sharings for starters. Quoting from Moz Resources 'At the heart of Link Building Campaign is the **asset **that would be used to attract and earn links, often known as "**HOOK" **that makes people care about what is offered and will entice them into linking to you. Also remember to backlink to active sites relevant to your content so that Google will not penalize you. Above are some insights for you to start on. Hope it will help! Cheers!
