External links are a very important factor in improving search engine rankings. If your site doesn't have enough external links, it's hard to get a high ranking for some competitive keywords. Getting the right external links at the same time is also very important if you have 20 good external links that will get a better ranking effect than the 100 bad external links. So what is a good external link to Johnny? The following points will make one link better than the other.
1, external links should be used in the anchor text keyword
If you want to get a high keyword ranking, such as "Buy brown shoes," the external link to your site should include the keyword "buy brown shoes" in the anchor text. Be sure that your external link anchor text contains the high ranking keywords you want to get.
2. External links should be from related pages
External links to the content of your site are usually better than external links that are not relevant to your site's content. Unrelated external links won't hurt your ranking, but Google prefers related external links.
3. Link external links to your most relevant pages
You typically point an external link to the home page of your site, but it's better if you point an external link to the most relevant page, such as a link in the anchor text containing the "buy brown Shoes" point to the page that sells the brown shoe content.
If the external link matches the content of the linked Web page, it is likely that your page will be related to the keywords contained in the anchor text to get a higher ranking of search engines.
4. External links from authoritative sites are better
External links from authoritative web sites will help increase the degree of trust in your site. If the external link has a high PageRank value, it will have a more positive impact on your site rankings.
Unfortunately, the PageRank of Google's Green toolbar is not used in the ranking algorithm, and the Green toolbar PageRank is usually outdated and can be misleading without practical help. You may find that some PageRank site pages are more likely to be in search results than those with high PageRank values.
5. External links must not have nofollow property
Nofollow properties tell search engines that they should not access a link. This property will make the external links no help to your search engine rankings. Unfortunately, you need to check the HTML code for the external links to see if they use the attribute to link to your site. You can use this tool to detect nofollow properties.
