I think bolding key sentences to help readability is a great way to go. People tend to scan webpages instead of reading every word. I don't think only bolding keywords is wise since it looks really tacky and probably has zero effect on your ranking for the targeted keyword. It might even be considered spammy.

The best way to find the best opportunities is to read a ton of blogs in your industry and develop relationships with the most popular blogs in your niche by doing things like leaving thoughtful comments or engaging in conversations. The best guest post opportunities are on high authority sites that will send you significant traffic. If anyone can get an easy link from a site with minimal effort it probably has minimal SEO value. A good sign is if the articles on the site have a lot of social shares like Tweets, +1's, and Facebook Likes.

I was wondering if the authority of individual pages is diluted when you add new pages (in Google's view). Suppose your site had 100 pages and you added 100 new pages (without getting any new links). Would the average authority of the original pages significantly decrease and result in a drop in search traffic to the original pages?

Do you worry that adding more pages will hurt pages that were previously published?

I found this excellent presentation with actionable tips for networking at conferences: Networking at Conferences - YouTube http://bit.ly/12hyjAz

Great tips! Thanks Sha and I hope to meet you at Mozcon.

Thanks everyone for the tips. I believe there is a Facebook page and the video access will be complimentary for attendees again this year.

Do you have any suggestions or tips for getting the most out of attending a Mozcon conference or marketing conferences in general?

I recently developed a nice article for a career site and they agreed to publish it as a guest post.

Once they published the article I noticed they had removed the link back to my site in the byline.

What is a best way to approach this situation? Would you ask them to take down the article if they are unwilling to link back to your site?

Thanks everyone for the tips. I believe there is a Facebook page and the video access will be complimentary for attendees again this year.
