Need SEO advice
Hi all, I have a 3 years old website that's is currently ranked well. 20+ articles. Two keywords was #1, few other keywords ranked from #4 to #7. I get around 200 UVs daily from Google. However one of my best keyword recently falled from #1 to #3. My traffic just slightly decreased but i'm worrying that if i dont do anything, competitors will jump over me at other keywords in future. I didnt do any SEO since almost 3 years ago.
I want to get that keyword back to #1 and also want to bring some others to higher position. Do you have any recommendation ? The process must be slow and steady because this site bring 80% of my income and i dont want to risk it
