With constant updates on Google’s algorithm, it obviously states that your website can get into major trouble if it has the wrong type of backlinks. Knowing this, the question remains: How do you judge the quality of a website? From which pages should you get links from?
To help you find good links that will help your Google rankings, follow these tips:
1. Always remember: All automatic backlinks are harmful
Automatically generated backlinks have no positive influence on the ranking of your website. So in case you tried to generate backlinks in bulks automatically, you should try to get rid of them to avoid a penalty.
2. You get lesser benefits from links that can be obtained easily
If getting links was as easy as uploading an image in some image hosting site and adding your link in the comment section or in the description section, it may not have an effect on your rankings.
3. You don’t need special metrics
New pages appear in google every day. So while it’s good to get links from pages with particular PageRank, having links from high-quality websites with a low Google PageRank is still acceptable.
If a high-quality website adds a new page, the new page will have an initial PageRank of zero. Nevertheless, the page can still be very good.
4. For lasting results, ask yourself these following questions:
- Does the linking page appeal on the average web surfer?
- Does the page have relevant and interesting content?
- Does it make sense if the web page links to your site?
If yes, then no matter if the linking page has low PageRank, you should try to get a backlink from that page.
