An online agent has claimed that the big players in his market are making it all but impossible for newcomers to establish themselves.

He claims they are doing so by driving up the cost of Google Ad words as they bid against each other to be listed on page one of searches.

The agent – who has asked for his identity and that of his business to be withheld – said the cost of a Google Ad word is escalating sharply.

He explained: “I run an online/hybrid estate agent model.

“We are enjoying building up a good reputation locally and online. However, a way of advertising is Google pay per click, which generates quite a bit of revenue.

“It appears the big ‘cash-backed’ online estate agents are forming a monopoly and trying to cut off the market to newcomers.

“It is now £5.85 per click on Google for the term ‘online estate agents’.

“This is a lot higher than many key market terms and bids by the online estate agents are driving up the prices to get on the first page of Google. Two months ago, it was £1.20. At this rate of escalation, it might soon hit £10 per click.

“This makes it impossible for newcomers offering alternative choice to realistically compete in the marketplace.

“Yes, we can build up a business, but are established online agents trying to squeeze others out?

“But this is not just hurting smaller, newer online agents but also driving up costs for high street agents.”

He went on: “I was approached by a specialist business that can run your Ad word campaign for you on Google, and was advised that it would me £3,000 a month for just one set of search criteria.

“There is absolutely no way that a new business could find £36,000 a year – but clearly it is no problem to the well-funded online agencies that have recently raised enormous sums.”

On Google pages, a number of paid-for entries are at the top and bottom, marked “Ad”.

These ‘pay by click’ spots are bought after bids have been placed, while all the other listings on Google are organic and cost nothing.

We carried out a number of searches and found that it is not just a search for “online agents” which shows how the wealthier online agents are dominating Google property pages.

The Ad spots can and do change, but on Saturday afternoon, a search for “estate agents UK” showed Purplebricks, Rentify and Tepilo having the first three spots on the first page.

A search for “online estate agents uk” showed HouseSimple, eMoov, hatched and Purplebricks with the first Ad spots.

The second set of Ad spots at the bottom of the first page were taken by Rentify, Settled and Tepilo.

Searching for estate agents by town or city also shows how active the online agents are in using Google Ad words.

For example, a search for “estate agents Leeds” on Saturday showed Ad spots for Purplebricks and housenetwork at the top of the first page.

A similar search for Manchester showed the first Ad spots taken by Yopa, housenetwork, and hatched.

Searching for “letting agents uk” showed that rentmyhome, rentify and Purplebricks took three of the four top Ad places.
