Just have a few questions as I'm entering SEO. 1. When I type in one of my websites in the tool (not really updating it anymore, just using it for CL service calls for PC tech work), it shows stuff about osTicket. I have taken this off my site approximately 1-2 months ago. Why does the keyword ideas still show os ticket stuff? 2. Where does this tool get its keyword ideas from? It shows things like "speeding up your computer" in the keyword ideas when I type in my blog's website. That keyword isn't on my page anywhere. 3. How does Google understand keywords on my site? I was told I should probably write a post per keyword (with high searches and low competition), but how will Google know what I'm using as my keyword? Not sure how it finds out. Any help would be appreciated, thanks.
