Not All Links are Created Equal
Nobody's gonna just link to your site because they're in a good mood. Your site needs to be full of great content and value for others to link to it. And people need to be able to find your site in the first place if you hope to get any inbound links at all.
So what you need to do, you need to create a link-building strategy. The main thing to think about, though, is that you want concentrate on the QUALITY of the links, not the quantity.
This means if a popular summer camp blogger provides just one link to your camp's website, that's better than getting five links from five different gas stations around town. The reason why is because Google will view the link from the summer camp blogger as a vote of confidence for your sight while seeing the gas stations as having nothing to do with your camp at all.
Now one thing you may not be able to do is control what the links pointing to your site say, but if you can, you're in really good shape. Let's revisit the summer camp blogger example.
Let's say the camp blogger provides a link to your website with the words, "check out this website." As we mentioned, just the fact the link is coming from the blogger's site to yours is a big deal for you. But if the blogger changed the link words to say, "check out this summer camp website," that's MUCH, MUCH better. The reason why is because Google is looking for the most relevant websites to return to a user when the user types in their keywords. When the users keywords match your link words, BINGO, you've hit the jackpot!
So it's pretty clear that not all incoming links are created equal. When trying to accumulate links for your site, you should be targeting popular sites that relate to your camp while trying to influence what the words in the links say, if you can. This is one of the main ways Google and the other search engines rank your site in their search engine results.
