Does anyone use SEO Services from WF

Quality has it's price.

A blog post for $1-$2 can never be good as there's simply no margin for written content so it's spun, often on over crowded sites.

Actually the same thing applies to blog posts at $5-$6, though those can contain written content, it would just be a short posts that rolls off so the gains are temporarily. In the end you need more and more of such links till the point it starts to leave footprints.

There are also people offering such blog posts with 100-300 words of content for $10-$12, claiming the links remains permanent on the homepage, often with 40 OBL. This is another problem as most of the sites feature the same clients, which leaves a large outbound link footprint and most of these networks end up deindexed within a year.

A good blog posts how ever, is preferably a post on a real website or as real as it can get, with few submissions per month and set up in such way that there's no linking from every single post or a permanent link on a domain shared with just a handful of others. Though those are not always natural the characteristics make sure you can hugely benefit from them. There's just one problem, such links would cost $20 upwards per post. Not really a problem one would think but when competing in a marketplace with people offering posts starting at $0,20/post up until $10/post it's very hard to sell such post for $20+.

That's why you hardly see anyone offering such links, it's simply not profitable due to the lack of volume. Funny thing is that I do offer these links and my sales threads have been alive for a couple of weeks now.

Guess how many I sold? ZERO

Actually I do sell these links on a very regular base to long term customers of mine but not through forum marketing. In the past I used to sell those cheaper posts as well, and back than they did their job but things have changed quite a bit and at a certain moment it turned out that these links became harmful so logically I changed my strategy and transformed my networks bit by bit.

So to answer your query, don't expect to find a better quality here than on sites like oDesk, Freelancer.com and such. Obvious there are some exceptions, however there are a lot of deceptive promises made in sales threads.

I can't count the number of times where I see people advertising whitehat SEO and when I look at the description of links I see the same old web2.0's, pdf/doc submissions, press releases, article directories, social bookmarks and so on. Not only have they zero relation to whitehat but such links are absurd weak that you can't rank a thing with them.

If you want long term results you have to learn SEO yourself first, and follow up with hiring a freelancer that you teach what you learned. The site backlinko.com is a great starting point for people who aren't afraid to put in some time on their own. He teaches true whitehat methods like link outreach, broken link building and these type of things. Unfortunately it's not easy to put in practice for many people as their sites are simply not link worthy. That's why PBN's (private blog networks) are so popular, but as said, most are setup in such poor way that they do more harm than good.

Lol good point. Odesk and such seems to be over crowded with Indians that gave up on SenukeX and now offer professional SEO in the shape of optimizing your meta tags and such

The funniest part is negotiating about price with such people. We all received those spam mails with an endless list of mostly onpage things and some public PR n/a links for something like $200-$300/month. A few times I made it a hobby to get it for as cheap as possible, lowest I was able to get was $35/month which pretty much relates to Fiverr gigs when you look at the work.
