teliad cannot guarantee that PageRanks will remain unchanged during the performance period. For this reason, the PageRank is not part of the booking, but always just up-to-date information alongside the additional offer data! PageRank changes are fundamentally risky for both sides; the seller bears the risk in the case of revaluation and the buyer in the case of devaluation. For this reason, bookings at teliad run from month to month, so that existing bookings can be either adjusted in regards to prices or also terminated very quickly if desired.

Price changes only apply to future performance periods that have not yet been invoiced for. teliad does not issue credits in the event of PageRank devaluations within a performance period, nor can claims be made for extra payment in the case of PageRank revaluations within a performance period.

teliad is aware that a PageRank change is annoying when it occurs shortly after a booking or extension. However, it is necessary to extend bookings in good time and changes to extension invoices do not make sense for several reasons. This risk applies to both the seller (revaluations) and the buyer (devaluations). teliad has no advantage from this! In this case, termination is first possible at the end of the performance period that has already been extended.

In general, we recommend that you are not too quick to terminate backlinks (for example in the case of PageRank changes). It is very important for Google (and also other search engines) that backlinks are set for long periods. Frequent changes in the backlink structure, i.e. a constant, unnatural changing of backlinks is more likely to be evaluated negatively. For this reason, price fluctuations for bookings should therefore also be viewed from a long term perspective.

The content relevance of the links now plays an important role in Google's evaluation. We inform our customers of this fact in many places on the marketplace and in our e-mails. The content relevance of two webpages is much more important than PageRank. Content relevance means that there is a relationship between the target URL and the offer URL in terms of content. This does not mean that the target URL must deal with exactly the same topic, but merely that some reference can be found between the two pages.

If a page contains thematically-irrelevant backlinks, Google often reacts very rapidly to devalue the page, particularly if pages have a very high PageRank. Please read our comprehensive "Link Buying Guide" which provides full information about these issues and offers tips for buying backlinks. The guide also contains valuable information about content relevance and about the PageRank.

On the subject of PageRanks, we would comment as follows:
If the PageRank of a page has been devalued, this does not mean that its ranking in Google is lower, as far as its own ranking or the benefit of backlinks to this page is concerned.

Inbound backlinks are the decisive factor for the Google ranking. The theory behind this is as follows: the more inbound links a page has, the greater the probability that the page contains "valuable" contents. The Google algorithm not only evaluates the number of links that link to a webpage, but also their quality, which can essentially be measured in three ways:

·    Is the page that links to your page thematically related to your page?
·    How popular is the page that links to your page (How many inbound links does it have? How high is its PageRank? How is the site’s ranking on Google?)?
·    How many outbound (external) links does the page have that links to your page?

The first criterion to consider when purchasing backlinks is the relevance of the link website to the target site. It is really not worth buying backlinks based on PageRank only. There are many factors that contribute to the ranking and simply going by PageRank is not sufficiently focused to offer long term success. This is also the reason why there is hardly a relation between a high PageRank and rankings on Google anymore.
