Domain authority
The simplest way to measure the value of different sites is to look at how they’re ranked by sites like Alexa, which specialize in establishing website authority. Bear in mind that this kind of measurement looks at the domain as a whole and that not all the pages within that domain will have equal value. Some types of sites almost always have high authority and rank highly in search engines, such as those belonging to governments, major international institutions, and newspapers.
Subject relevance
To provide really valuable links, sites need more than just a high level of general authority – they need to have authority in the same area as your site. They could be dominant companies within your sector, trade journals, academic websites related to what you do, or relevant government departments. These links will tell both human readers and robots that your site is considered important and is worth prioritizing in searches about what you do.
Local relevance
Increasingly, SEO services in the US are encouraging their clients to think local, and this is no less important when link building. If you run a locally-based business that trades within a limited area, you’ll need search engines to associate you with that area, and this kind of link building helps with that. Useful sites will have strong local connections and include a reference to multiple places nearby.
Site links
When you’re assessing the quality of a site for use in link building, it helps to look at its links. See what it links to and then track back to see what links to it. If it has a substantial proportion of poor quality links in either direction, it could be problematic for you to be associated with it, even if it looks promising in other ways.
Update frequency
Good quality sites can also be identified by the frequency with which they’re updated. No matter how impressive it is in other ways, a site that hasn’t been updated for a year or more might as well not exist as far as search engines are concerned, and if it is to retain a high position in the rankings, it will need to be updated at least twice a week. By analyzing these simple metrics, it’s possible to find the ideal combination of sites for any specific link building project. Every site’s linking needs are different, and it takes expert skill to establish the best connections, but with this approach, you should at least be able to determine whether or not your SEO experts are doing a good job.
