Hello, I run an Indian lyrics website, the two year old site results currently ranks between 1 to 5 ranks on the SERPs, but, not always on the first rank. Only one or two competitors are ahead in our niche. I had analyzed that we've have lesser links in comparable to our competitors, and I am too busy to generate content on my site, so I've no extra time to work on link building , Therefore, I want to hire you guys for improving my site's search result rankings. I want you guys to take a look on my site, analyze the content, let me know the possible suggestions to improve my site's search ranking, link building, disavow the bad links, and simultaneously enhancing the user experience.
