SEO external measures and precautions

When it comes to SEO external measures, the acquisition of external links is often the main measure.
That's because Google used PageRank-centric algorithms as a ranking determinant in the past, but in reality it's not just about adding external links.
On this page, I will explain the points when taking external measures.

  • PageRank is just one of many algorithms
  • Using an IP distributed server carries the risk of penalty
  • Be aware that the anchor text is also natural

Understand PageRank

PageRank(Page rank)Is Google's algorithm for determining the importance of a web page.
It is a core technology related to external links. Basically, the more links from external sites, the more important the linked pages are, the more links are made from pages with a higher PageRank than those with a lower PageRank. increase.

The basis is likely to be an index to measure the importance of academic treatises.The more important a treatise is, the more citations are made, so when evaluating an academic treatise objectively, the number of citations from other treatises is one of the indicators... That gave rise to PageRank's idea that pages with more links are more important.

Don't stick to PageRank

In the past, PageRank was an important algorithm among Google's ranking determinants, so in order to capture PageRank and aim for higher display on search engines, measures to increase external links (backlinks) = SEO measures It has been regarded as important as it is said.
However, artificial external links such as pay drinks that require you to pay to set up links and artificial external links such as building your own satellite site and setting up links on your own site are now subject to penalties rather than evaluation. ..
Keep in mind that naturally occurring links are valid.

By the way, as of 2020, there is no way to check PageRank.
Previously, you could check the PageRank by installing the Google Toolbar in your web browser, but the PageRank on this toolbar is no longer updated.
Google stopped publishing PageRank because of the prevalence of pay drinks and self-made links, which I mentioned earlier, and the loss of health of the entire Web, because of the belief that the higher the PageRank, the higher the ranking.

Sure, PageRank is still part of the algorithm, and while it's an important algorithm for Google as one of the determinants of ranking, it's only one of over 200 algorithms.
Even if you stick to PageRank and only acquire external links, it does not necessarily mean that you will be ranked high in the search results.It is.

Domain distribution and IP distribution

Words that often appear when considering external measures for SEO are "domain distribution" and "IP distribution". A domain corresponds to the address of a website, but distributing the domains of the link source site by pasting links from websites of different domains is called domain distribution.

In addition, IP is a unique identification number assigned to computers and communication devices, but distributing the IP address of the link source site by attaching a link from the website of a server with a different IP address is called IP distribution. increase. Both have been regarded as effective measures when raising the display ranking on search engines by external links.

Risk of domain / IP bias

When artificially constructing a large number of external links in an attempt to increase the number of external links, it is likely that you will often ask a vendor, for example. In that case, the limited websites used by the vendor will often link to your site. In other words, there will be more links from websites with the same domain and IP address.

However, if external links are built naturally, the links should come from websites with different domains and IP addresses. Search engines such as Google, which dislike building artificial external links, are naturally aware of this. If an external link is built by a large number of inbound links from the same domain / IP address, but the search engine evaluates it, it is easy to unfairly build a large number of links. Will be.

Therefore, search engines such as GoogleIf it detects that a large number of links are installed from the same domain or IP address, it may impose a penalty on that website...

To avoid this situation, try to distribute domains and IPs instead of artificially building links with ease. If you want to artificially build a link, you should have a unique domain for all 1 link 1 link.
We recommend that you have an IP address. However, that would cost a lot of money.

Beware of IP distributed servers

I think you can understand from the explanations so far that domains and IP addresses need to be distributed. Against this background, many SEO companies have tried various methods to acquire domains and IP addresses in a distributed manner.

One of them is called an "IP distributed server". An IP distributed server is a rental server that provides different IP addresses as a package. This is generally a package of some IP addresses borrowed from different hosting server companies. It was decided to bring it to external measures that require a large number of IP addresses, and it was actually used by many SEO countermeasure companies.

Problems with IP distributed servers

Link from IP distribution server
But I want you to think about it here. Where is the need for such an IP distributed server? In conclusion, there is only a need to build SEO-aware artificial external links. In other words, it is very likely that most of the other websites that live with the IP address provided by the IP distributed server service are also websites for building external links for SEO purposes.

From a search engine's point of view, artificial link sites built for external links are probably worthless. Other websites that live with the IP address of the IP distribution server are also likely to be such worthless websites.

After all, the IP address provided by the IP distribution server is very likely to involve a large number of worthless websites for external links, so the IP address itself is spamming from search engines. There is a high risk that it will be recognized as an IP address. Websites that receive links from websites with such IP addresses may be the first to be noticed and penalized as websites that are artificially linking.

For this reason, using an IP distributed server should be avoided as much as possible. If you ask an SEO company to build an external link, we recommend that you check if you are using an IP distributed server.

Importance of anchor text

Anchor text is the text that is the link on your website. Called an anchor tag<a>The URL of the link destination is specified by the tag,<a>When</a>Anchor text is written in the part surrounded by. If the anchor text properly points to the linked web page, it will be easier for both users and Google to understand the linked content. Anchor text, like a road sign, points to what&#039;s ahead.

Because of these characteristics, the measure to include keywords that you want to be evaluated by search engines in the anchor text is considered to be one of the basics of SEO measures. If the anchor text for linking to your website contains the keyword, the search engine will recognize it as a web page related to that keyword. As a result, it leads to an improvement in the display ranking when searching with that keyword.
Search results for "No"

As proof of that, let's look at the search results for keywords such as "no" and "exit" on Google. "No" or "Exit"
If you search with, Yahoo! Japan will be displayed at the top. It may seem strange because Yahoo! Japan is not a website that deals heavily with "no" and "exit". This phenomenon occurs when Yahoo! This is because there are many cases where Japan is set. In other words, as a result of collecting many links with the anchor text "No", Google received a rating with the keyword "No", and Yahoo! Japan is displayed.

Be aware of natural anchor text

You should understand the impact of anchor text on search results. However, we do not recommend mass-producing anchor text that contains too many targeted keywords. Even if it is a proper noun, such keyword-covered anchor text is unnatural. Because search engines focus on natural links, they can penalize websites that collect such unnatural links and even lower their search rankings.

To avoid this, try to make the anchor text itself natural. As with domains and IP addresses, the content of the anchor text should also be distributed. Note that you don't just have to pay attention to keywords to build a natural link for anchor text. Variations are also required for the character strings used in the title tag and URLs. Natural links often have a wide variety of them, so the risk of penalty is lower as you get closer to the situation.
