I don’t think abuse of the search engine is necessary for a track to gain momentum. In fact, I’d say any more than 3-4 keywords and you’re doing your track a disservice. It is most certainly not paying off. Granted I’ve experimented with 4 word titles before, but I honestly don’t think it helped.
Let me elaborate:
Buyers will often search more than one popular term. As long as your track appears in one or two of those corresponding results pages, you’re fine in my opinion. Adding a sentence-long string of keywords will NOT help you here. It will make your title harder to remember, and it will blend in with the rest of the tracks. A 2-3 keyword title is actually optimal in my opinion.
The main issue here is abuse of the automatic approval system. Authors are uploading tracks as 1-2 word titles (which get manually approved), then proceeding to change them to sentence-long word salad. Normally AJ reviewers would reject titles like this, but because “trusted” authors can pretty much change what they want with auto approval, they’re free to wreak havoc on their titles.
Notice how NONE of the top sellers’ sales changed after adding an extra keyword or two to their titles. I’m talking LumenMedia’s smash hit “Upbeat Corporate” - it did just fine with 2 keywords. Studio89’s track “Upbeat” (later “Upbeat Corporate”) managed fine as well. RedLion’s “Inspiring” is doing better than ever and it’s a single word title! My point is that that there’s a sweet spot - and it’s probably 2-3 keywords. Even my track, which used to be called “Uplifting and Inspiring Background” (only 2 useful keywords), didn’t really sell any more after adding the keyword “corporate” to the title.
Unfortunately many authors think that by adding more keywords they are increasing the sales potential of the item by upping the exposure. Wrong. In fact, by continuing to subscribe to this idea you’re not only damning your own work but you’re reducing exposure on other tracks as well.
Let me finish with this. The only way you’ll benefit from having a keyword in your title is if your track perfectly reflects that keyword. Minldlessly adding keywords will not help you. I’ve seen many authors begin to tack on words like “motivational” or “epic” to their otherwise light and inspiring corporate tracks, thinking that this will improve their sales. On the contrary, what they’ll notice is that the track won’t sell anything more (eg buyers find the track after searching epic and don’t even bother visiting the page because the track sounds nothing like an epic track) Instead, the new title only serves to confuse buyers and crowd the search results.
