Anchor texts: which versions are effective?

[dave.]

Hi,

I have a new plan for getting high pr backlinks by creating accounts at well established sites. However the problem is that I can't use spaces in my anchor, so it's hard to get a useful anchor for long tail keywords.

So if you were targeting let's say "article marketing" what do you think, how effective are the different anchor text variations for getting the highest quality backlinks for long tail keywords?

article marketing - normal anchor text, which is not possible here
articlemarketing
article-marketing
article_marketing
other ideas?

I don't know how valuable the last 3 versions are, so if somebody has experience with this, please let me know your opinion!

Thanks, Dave

Hi dave,

Google treats a hyphen the same as a space, so I would go with the hyphenated version.

Thanks for the aswer.
And how about articlemarketing? If I write the words together, could it help to rank for article marketing (beyond the "every link is a link" theory)?
