As I had been working for the past month on Riff Channel, I’ve learned so many details about SEO. We changed several times the meta tags and even considered giving up some keywords since their practicality is doubtable.
Reading the topics on the web surely helps, as well as reading the Google dos and don’ts.
Another useful hint is to check your more successful competitors. Not just the layout of the site, also what hides under the hood. Actually, compare some SEO of top ranking sites, check meta tags in the home page and single pages.
Will post some resources in a while.
