Hello friends. After learning a lot I finally spent some money to start a site. The KW is good and does not have high competition. When I started doing SEO initially saw some movement and ranked four of my KWs in less than 100 rankings but now nothing seems to be working. All my KWs dropped and now only 1 KW is ranking on 187th position. Here is what I have done so far. Created a site focusing one main KW and around 10 LSI and long tails Added 17 articles of around 500 words with images and vids. Two or three of them are amazon reviews. Focused different KW in each article Off page: Created four Web 2.0s mannually focusing different KWs Added 5 articles to them. All hand written and unique Linked to relevant post (Also linked to a related authority site). In one web 2.0 I used naked url, in rest anchor text. Then I made around 150 links each to 3 of the tier 1 web 2.0 (Using around 20 KWs, general KWs, naked urls and different variations) After doing off page SEO II saw KWs appearing in ranikngs. But when I stopped doing SEO KWs gradually disappeared. What am I doing wrong? Should I keep doing SEO to keep improving rankings? Or Is it not enough SEO to give me a stable SERP at what ever position my KWs had gained(why did they drop)?
