How to pick a good SEO Service here?

Hey,

the last time I bought a SEO Service from here my MNS was on #1 for a few weeks but dropped
badly after I stopped using the Service.

So I want to try it again with a new site but I have a few questions:

How long should I pay for a SEO Service?
Why do some charge 300$/Month for it and others 5$? (one time)
How do I know if the SEO Service is good quality and long-term?
My site has 10 articles (+/-10.000 words) targeting 30 low comp. keywords - do you think this is enough for good ranking?

And most important question: what will harm my ranking at all?

Thanks for your valuable time reading my thread

They are a bit hit-and-miss. Some work like gangbusters for a few months, then die. Here's your best bet:
1. Keep making and posting original content on your site
2. Build new content on web 2.0 sites, YouTube, guest posts, that point back to your site (don't forget inner pages). Share it on social sites.
3. Build links to all the sites in #2

The fees are usually correlated with the amount of work required or the value of the links themselves. Ideally, you want high DA/PA sites related to your niche.

It may or may not hurt your ranking...depends on your site. I've had sites blasted by competitors with spammy keywords, and it only boosts the site. Then again, I've spend 000's on a site, all original content, manual link building, good social platform interaction, and seen it die. If there was a guaranteed method, the owner of the method would be a billionaire.

Just look for things that are sold here that have a lot of feedback and a good track record...

thanks this was already helpful to me will take action now
